The bere line – rhymes with hairline

Rhymes with hair line …..

In Landrace 1 – bere the query arose as to whether there was a bere line from the neolithic (late stone age), a line of transmission of bere (barley) seed from the first settlers in these regions to the present day. Another question was when bere and barley became  distinct – they are the same plant species, but just look a bit different, close up.

So since bere is our most famous and still-grown-in the-wild-but-only-just cereal landrace, the Living Field will explore the bere line as a fairly random walk through time, backwards and forwards that is,   putting facts and photos on this web site as we find them.

At some point in the future, we might order them into a chronological list, starting with the earliest and ending with the most recent, but ‘random’ suits us for now.

As an introduction, here are some photographs of bere barley on the left compared with a 2-row barley on the right.

Bere in Lawsons’ Synopsis 1852

Lawson and Son’s bere and barley varieties, 1836 and 1852. Bere and two-row barley clearly distinguished. Several extant bere landraces, attempts at improvement. Types like bere grown across northern Europe.

In their Synopsis of the Vegetable Products of Scotland (1852), Lawson and Son list the names and characteristics of all varieties of crops and other useful plants known to have been grown or tried by them or their correspondents in Scotland. The 1852 Synopsis built on their earlier Agriculturist’s Manual (1836). They must have been growing all these different types of plant in their experimental gardens and plots near Edinburgh throughout the 1830s and 1840s if not earlier. Their Synopsis was a major achievement. It has not been surpassed.

Was bere listed?

Under barley, ‘Common Bere’ is listed among the four-rowed barleys (see note below on four- and six-rowed barley), but of particular interest are several other types that appeared very close to bere. Since most of these types were kept and grown from saved seed, they made a set of landraces, certainly not pure and probably overlapping in many characteristics.

So was common bere a distinct type? Lawson and Son frequently used it as a standard, comparing others to it in terms of structure and timing. For example, there were types that looked the same as bere growing on mainland Europe, one of which was ‘probably the same variety’. Then there was the higher yielding ‘Victoria bere’, and several naked forms (the ‘husk separating from the grain in thrashing, as in common wheats’), including ones said to be superior to the ‘Old Scottish four-rowed naked’. There were also several four-rowed types originating from other parts of the world, outside Europe.

Was there more than one bere landrace?

Their account, while not mentioning separate landraces within the bere grown in Scotland, suggests a situation more complicated than a single class of northern barley landrace that was generally called bere.  The name ‘Victoria bere’ suggests bere could be of different forms. The Living Field has not yet found evidence from subsequent records of what happened to the various bere-like barleys. Did any become more widely grown? Were they all classed as bere in some future time?

In the Lawson’s time, and for another century, oat was the main cereal here, but as barley increased in area and overtook oat to become the most widely grown crop today, it was mainly the two-rowed barley that came through. Certainly, most of the four-rowed recorded by Lawson and Son seem to have disappeared.

So – from the Lawsons’ books and records – bere in Scotland in the 1800s was structurally distinct from two-rowed barleys, but was not   that distinct from a range of bere-like forms grown on mainland Europe and beyond.

The Lawsons’ books also give evidence of the wealth of international connexions in the seed trade and in the desire of farming to seek improved crop varieties wherever they could be found, whether from a few unusual ears in a field in Scotland or from occasional samples from Nepal, Morocco or … the list is endless.

Further details of bere and other four-rowed barleys

Lawson and Son distinguished four-rowed, six-rowed, two-rowed and an usual type named ‘fan’ or ‘sprat’ barley.

Presumably reflecting the usage at that time, they classed bere and several other barley types as four-rowed. In their earlier Agriculturist’s Manual (1836) they write of Common Bere and types similar to it – ‘middle grains on each side forming a distinct straight row; lateral ones forming a kind of double row towards the base, but uniting so as to form one row towards the extremity of the spike; so that instead of being named four or six-rowed, they might with more propriety be named four and six-rowed barleys.”

Common bere is described as ‘ear about two and a half inches long, containing about 60 grains … and ‘awns or beard about three and a half inches long, adhering to the grain’. In their Agriculturist’s Manual, they state the bere grown in 1835 in trial plots in Edinburgh was sown 7 April, in ear 27 June (81 days) and ripe 12 August (127 days).

The description of the type referred to as Victoria bere suggest attempts to improve the existing landrace. This type ‘produces longer straw, is longer eared, often containing 70 to 100 grains”. Where did it come from? A Mr Fulton, in Ayrshire, is credited with ‘bringing the Victoria bere under the notice of cultivators in this country’. He obtained a few ears of it from the Belfast Botanic Gardens in 1836 and he must have bulked seed for extensive trialling from those ears.

Several others are compared with common bere. Winter white has ears thicker and longer than bere, and its grain sample is coarser. Sown in the autumn it acts like a modern winter variety, ripening earlier than the spring types, but it can also be sown in spring, ripening later. Winter black also had ears larger than bere, but of a ‘black or dark bluish colour’ best sown autumn because if sown late in spring it will not mature the same year.

The variety Square is evidence of similar varieties to bere grown on mainland Europe, being cultivated in France and Germany. It differed from the common bere by being ‘three or four days sooner ripe, and having a thinner skin’. There authors suggest it is probably the same variety (as common bere).

Also, the variety Naked (also known as Siberian barley), which superseded the ‘Old Scottish Four-Rowed Naked‘, which is ‘still a favourite in many districts of Scotland’. Naked’s ears are similar in shape to the common bere but rather more distinctly six-rowed, containing a much greater number of grains. It was grown extensively in the north of Europe, and even in parts of France, and despite ‘its cultivation now almost abandoned … it certainly deserves a fair trial in this country, particularly in the north of Scotland, where it might form a valuable acquisition on account of its earliness, being ripe about a week before the Common Bere’.

Of the 11 other four-rowed barleys listed, some are from overseas, for example African also known as Tangier or Morocco barley (stated as no longer cultivated), Bengal, Nepaul or Himalayan introduced 1817 and Peruvian (described as a superior six-rowed).

Note on Six rowed barley

Entries on six-rowed barley include only two types, one of which is imported from China, but appears the same as the other listed, True Six-Rowed Barley. They describe the awns of this adhering to the grains ‘with great tenacity’ and ‘the coarsest in sample of any of the barleys, but hardy and prolific’, sown as a winter or a spring type, and nearly a fortnight longer to maturity than bere.

Thorburn’s diagrams

The bere line – rhymes with hairline

Thomas Thorburn used diagrams to get a point across: for example, diagrams  in the form of  squares to represent large numbers of things. If the reader was no good with figures, then they might get a better idea by comparing two squares of different size to see which was larger and which smaller, and by how much.

His “Diagrams, Agricultural Statistics of Scotland for 1854” was based on agricultural census data collated by the Highland Society and gives areas grown with various crops and output in total bushels of grain and in bushels of grain per acre, including those for barley and bere.

Title page of ‘Diagrams’ by Thomas Thorburn, set by the Living Field on a greyscale image of an Orkney bere field (Living Field)

Bere (or bigg) and barley are clearly distinguished in the pages of Diagrams as different crops.

Summary

The agricultural census in Diagrams tells us much about bere and barley in the 1850s.

  • Bere was grown mostly in the north and west, but occurred in most agricultural census regions. Farmers throughout Scotland would have been familiar with it.
  • The area in Scotland sown with bere was just less than 10% or one-tenth that sown with barley.
  • Yields of barley and bere, when expressed in modern units were both 1.5-2.0 tonnes per hectare (t/ha), compared to present national average yields of 5-6 t/ha for spring barley.
  • In Scotland as a whole, bere yields were a bit less than those of  barley (about 80% or 90% depending on how yield was calculated), but where they were both grown in the same area, as in some northern and north-eastern regions, their yields were similar.
  • Bere has now almost disappeared as a commercial crop, whereas barley is the most widely grown corn in Scotland, going mainly to malting and animal feed.

Where was bere grown in the 1850s?

The area grown with bere in 1854 was about 9% of the area of barley. So in the whole of Scotland, just over ten times more barley was grown than bere. And while most bere was grown in the north and north-east, in places such as Aberdeen, Orkney and Shetland and Caithness, it was grown in a small area in many other places, including areas such as Haddington which are considered to be high-yielding. (The names Aberdeen, Orkney and Shetland, Haddington, refer to census areas.)

Here are some figures. The area grown with bere in census regions was, at the top end, Aberdeen 5322 ac, Orkney and Shetland 2922 ac, Caithness 2710 ac, Argyll 1888 ac; and at the bottom end, Perth 502 ac, Haddington 40 ac and Roxburgh 6 ac. The abbreviation ‘ac’ refers to acre, which is about 40% of the hectare, the present metric unit (1 acre = 0.4047 hectare; a hectare can be visualised as a square of 100 m by 100 m).

For barley, the figures at the top end were Fife 27,938 ac, Forfar 25,222 ac, Perth 23, 710 ac, Berwick 16,576 ac; while figures in the north and west were Orkney and Shetland 149 ac, Caithness 265 ac and Bute 389 ac.

What did it yield

Thorburn gives yield in bushels per acre, bushels being a measure of dry volume, used for grain, and acre being a unit of area widely used until recently, and still used locally. He gives the total bushels produced in each census region (from which bushels per acre can be calculated by dividing bushels by the area of the region) and in a separate diagram, he gives bushels per acre for each region. The two estimates are not always the same, so here we use Thorburn’s bushels per acre figures rather than our calculated figures.

Using standard conversion factors and our estimate of 1 bushel of bere = 21.8 kilograms (see Light on bushel), the national average yield of bere was 1.77 t/ha (tonnes per hectare) and of barley 1.93 t/h, so the yield of bere was just more than 90% (nine tenths) of the yield of barley.

The yields vary between regions, but where both barley and bere are grown together, especially in the north and west, the yields are not that different. In Caithness, for example, barley is 36.0 bushels per acre and bere 36.5 bushels per acre.

Caution

In Diagrams as it appears online, there is no description of the methods by which the census was conducted. It is presumed the Highland and Agricultural Society of Scotland did the work and handed the information to Thorburn who constructed his diagrams.

The yields of crops would have been difficult to measure consistently in the field or on the farm. Harvested grain differs in water-content depending on the weather, the locality and the variety of the crop. And grain also will differ in how ‘clean’ it is , how free of the bits and pieces of plant material that may be harvested with it. Today, yields reported in the annual census are given to a stated water content; so if the actual content measured in the combine harvester or in the grain store differs from this stated content, then the mass has to be corrected to allow comparison of near-dry mass between fields, farms and regions. No indication is given in Thorburn of how the dryness and cleanliness of the grain were standardised across regions.

The way the bushel was measured also probably varied. Perhaps some farms used a standard bushel measure (e.g. a barrel or basket) whereas others might have used a container, such as a cart, that they knew held a given number of bushels.

And then the areas sown with the crops were stated very precisely, sometime to several hundred thousand acres and three quarters. But were all fields measured so precisely? What if crops were grown in strips or parts of fields – was the area grown with each strip or part measured? It is difficult today to measure accurately the area of all fields in Scotland sown with a particular crop – and that is with all the official demands to record what was grown where and when.

Despite these uncertainties, the census was a major achievement. It must have taxed the Highland Society’s officials and local organisers. And they probably did have a very good appreciation of areas and outputs. But in some regions they appear to have come up against difficulties that were too great – for example, the yield of bere in Orkney and Shetland is omitted from Thorburn, despite much bere being grown there.

Bere and barley at the Living Field

Bere, bear, bair, beir, bygg

Now here’s an informative article by Iseabail Macleod on the occurrence of names for corn from the 12th century to 1700.

The article starts with: ‘What does the terminology of cereal crops and their products in the Dictionary of the Older Scottish Tongue (DOST) tell us about the language and diet of Lowland Scotland in the period? Her review of the records leads to the statement “Cereals … after 1550 became dominant, as the most economic way to feed a growing population. The earliest staple crops were oats and bere.” Wheat is stated as a “the food of the privileged, a cash crop and not normally consumed by ordinary people.” The author says that the best sources of information are “administrative documents, including court and burgh records, and the Treasurer’s Accounts.” (Ed – agreed, conventional histories the world over hardly mention what feeds the people.)

Wheat the food of the privileged then? Not so true today – many people eat imported wheat as white sliced or cereal nibbles,  while bere is becoming a gourmet delight.  (Just think) bere bannocks,  made from Orkney bere-meal and pure water, cooked on a cast iron griddle wood-fire-heated, drizzled with home-grown cold-pressed lime-infused rapeseed oil and enjoyed with a glass of micro-brewed Colonsay or Arran (Source: gourmet trials in progress, Living Field).

Bere and barlie

Barley and oats have kept northern people going for thousands of years (north of the sub-tropics and mediterranean, that is) and both of these cereals appear together in DOST. But do the records tell us anything about the difference between barley and bere.

Macleod writes that in DOST, bere also occurs as bear and bair, also beir. Big or Bigg (from Old Norse Bygg) “does not seem to be in the DOST record” “though it occurs in Northern English” and more recently in Scots after 1700 (see SND).

So bere, bear and bair (also beir) were used before 1700 in Scotland, but what about barley? Macleod writes that the word barlie was used as early as about 1500 but that barlie and barley are both rare before 1700.

But were bere and barley different in those days? Hard to tell. Macleod cites the use of the term ‘barley beir’, but (we ask) was this a form of barley or a form of beir, or was it just that people sometimes used both words to mean much the same thing or simply just got confused?

Conclusions

The various forms of bere and barley were found in the DOST records, but the forms of bere were more common. The forms of bere were used a couple of hundred years before the Scandinavian bigg was first recorded. The article gives no firm evidence either way that bere and barley were regarded as being different things.

Landrace 1 – bere

Barley Hordeum vulgare has been grown here as a crop for many thousands of years. Some of the earliest charred remains of seed found in neolithic settlements were of barley.  It has not always been the most widely grown corn – oat had that status a century ago – but now barley covers more acres than wheat and much more than oat, its main products whisky and animal food.

Most modern varieties of barley are supplied by seed merchants. The seed for each variety is grown and bulked under controlled conditions that minimise impurity and keep the line genetically uniform, so each has a particular ‘look’ and growth characteristics and suitability for different uses. At one time however, all our crops were maintained as landraces, as seed from one harvest saved for the next. (See What are landraces?) Few landraces remain and one of those is bere barley.

Where did bere come from?

Like all our corn, or cereal, crops, barley started life in the eastern Mediterranean or west Asia when crops were domesticated from wild grasses around 10,000 years ago. From there it came west and north reaching the croplands around 5000 years ago, well after the ice retreated.  The earlier Living Field web site had the following paragraph –

“Imagine the small bags of seed, carried overland step by step, century upon century, from its site of domestication to the east of what is now Europe, and then by small boats to Iberia, then Brittany and north to the stone age settlements of the north-east Atlantic coasts, or else by other routes through central Europe and across the North Sea. How many times must those bags have perished and how many times must the boatman have reached dry land to see the seed rotted and the crops fail. And yet, 5000 years or more later, we still have a landrace of barley, known as bere (sounding in the north more like bear than beer) and still grown for special food and drink.”

When you see or experience the seas around Orkney (images above) and the other islands, you wonder how our early settlers managed to get here carrying bags of grain in their small boats.

Does any of that ancient barley remain?

Is there a continuous ‘bere line’ from the stone age? There can be no certainty. Landraces can be erased by natural calamities, or by peoples moving or changing their way of life. When a seed stock was lost, it might have taken centuries for new seed to be brought in. Later, waves of migrants from south and east would have brought their own seed with them.  Where the new seed came from  is not clear.  What we can say is that the bere still grown today is very different from modern varieties.

In Lawson & Son’s catalogue of 1852, bere or rough barley, was listed among the four-row barleys. Most of the barleys at that time were two-row.  The number of rows refers to the alignment of grain on the ear, obvious when you see it in two- and six-row types.

The four-row types, as Lawson and Son suggest, are probably better classified as structural variants of the six-row types. But the four-rows look different from the six-rows, so on the Living Field site, we will continue to call bere four-row. In the rough and tumble of subsistence agriculture over the millennia, the bere landrace, maintained as harvested seed saved from year to year, must have contained at various times, as well as the four-row, two- and six-row types within it.  Purity is not a feature of landraces.

Bere has now almost disappeared except in some remote corners and most commercial fields you will see are two-row. Yet bere has great significance as a traditional crop, a true heritage and a possible source of genetic material for future crops.

The Orkney bere

A landrace of barley is still grown and used in a few places, notably in Orkney, where fields are gown each year to supply grain to the Barony Mills, near Birsay (images above). When the grain starts to fill and ripen, it has strong, characteristic red bands on the outer husk of the grain (images below) and long, tough awns.

As in most barleys, the protective coating around the grain does not fall off after harvest (as it does in modern wheat, for example), so the husks and awns have to be removed to get the bere meal (flour).  Once, bere grain and other corn was ground between stones, then in stone saddle querns and later by hand-turned stone wheels, one on top of the other, and then by great mechanised grindstones powered by wind or water.

The Barony Mills in Orkney grind local bere grain into flour by great water-powered wheels. The Mills sell bere meal to the public (web link below). Bere grain is also sold to a few distilleries to add that something to the malt whiskey.

Barony Mills is an excellent place  – an essential visit for anyone interested in rare grain and flour and living industrial heritage; and if it’s spring or summer, ask for directions to the bere fields.

The Living Field’s bere crops

The garden has grown bere for several years. The crop is grown in the Garden as a landrace – seed is harvested, saved over the winter and sown the next spring.

The bere seed germinates quickly, after just a few days, and once outside is vigorous in its vegetative phase and then flowers and seeds profusely. As a seed stock it does not give any problems and requires no special treatment. As with all seed, it has to be kept dry between harvest and the next sowing.

The red striping on the outer husk, or covering of the grain, is visible upper right and lower left below. The seeding ‘ears’ tend to bend and together the awns form an asymmetrical fan, visible in the image at the top of the page and in the one upper left below.

Each year, a few two-row plants emerge in the bere. They could be impurities introduced from commercial varieties grown in the garden? We take them out to preserve the general bere character.

Growing bere and other landraces in the Garden has been  rewarding for the team and brought great interest among visitors. We start it off in April, it begins to flower in early June and is ready for harvest usually in August. It does not seem to have changed much in the last 180 years: Lawson and Son, in their experimental trials of 1835, record they sowed it on 7 April and it matured on 12 August after 127 days.

The Living Field’s original bere seed was given to us by the Agronomy Unit at Orkney College. For which, many thanks. Barony Mills, Birsay, Orkney, also gave us a couple of bags of grain. We have bought flour from them for demonstrations at various open days. Thanks to miller Rae Philips for advice.
