Farming a new
approach to spirits

NO FUNGICIDES
NO HERBICIDES
NO PESTICIDES

At the very heart of our spirits is the seed we plant; the seed that grows the grain we distil, that with time and skill (and more time) becomes the spirits we sell, the dram we drink and the moment we share with friends.

And our seed isn’t just any old commercially-grown, bought-in-bulk seed. We are the only distillery in the world to use populations of ancient heritage grains to produce our full range of spirits. It might not be the economical way to produce spirits but the flavour profile these grains produce, and the environmental benefits, pay it back in spades. Our commitment to soil quality, land regeneration, community and the environment goes beyond our passion for spirits.

It was our chance encounter with Oxford-based archaeobotanist, grain expert, and now our farming partner, John Letts, of Heritage Harvest Ltd, at a farmers’ market which, if you’ll excuse the pun, gave our idea its roots and established the fundamentals of our farming.

So what about these ancient heritage grains. Why do they matter? And what does John do that’s so special?

First we must begin with a brief lesson in botanical history

Hunter-gatherers living in the Middle East over 20,000 years ago were the first humans to grind the seeds of wild grasses into flour to make flat breads. The first domesticated wheat (einkorn) and barley arrived in Britain over 6,000 years ago, and later settlers brought emmer wheat which fed the communities who built Stonehenge. Spelt wheat brought over from the Continent was the staple grain of Provincia Britannia during the Roman period, whereas the Saxons who came after them preferred what is today called ‘common’ bread wheat and rye. The Danes, Normans and countless generations of Medieval travellers who followed also carried seeds to Britain from Europe and beyond. Those that grew well mixed in with existing crops which slowly evolved into locally-adapted ‘landraces’.

A landrace develops over centuries when a mixed population of crop plants adapts to local growing conditions. It is evolution at its most elementary: varieties that do not grow so well produce less seed and are gradually outcompeted by better adapted lines. This improves the crop’s resilience and its yield. Because growing conditions change from year to year, a landrace also retains a lot of genetic diversity which allows it to adapt to longer term climate change. 

In Medieval England every valley, village and manor grew its own unique, genetically-distinctive, landraces of wheat, rye and barley for baking and brewing.

In 1994 John discovered over 200 almost perfectly preserved examples of traditional wheat and rye landraces in the bottom layers of thatched buildings dating from the late Medieval period (1375-1550 AD). His work showed that, in spite of poor soils, these ancient crops grew to over 1.5 metres tall. and that if these fields had been manured crops would have grown much taller and fallen over in the wind and rain, ruining the harvest.

Feeding a newly industrialised nation

Until 1994, no one actually knew what ancient English landraces of wheat or rye had looked like ‘in the field’ because none had survived in cultivation. They were lost when farming in England was industrialised in the early 1800s. Rye was all but abandoned, and demand rose for purified and higher yielding varieties that produced a lighter, whiter loaf. The landraces that had evolved in farmer’s fields over centuries were gradually replaced by a handful of purified ‘heritage’ varieties selected from the old landraces by seed merchants.

In spite of these changes, and the invention of artificial fertiliser in the 1840s, wheat growing collapsed in the 1880s as Britain was flooded by cheap, high protein (gluten) grain imported from hotter countries such as Canada and the Ukraine. To save the industry the British government hired scientists to create new ‘hybrid’ varieties that could produce higher quality flour in UK conditions. The release of ‘Victor’ (1906) revolutionised grain production in England, but these new varieties produced bumper crops only when grown with artificial fertilisers. In the following decades, and particularly during the so-called ‘Green Revolution’ of the 1960-70s, biodiversity disappeared as crops were dosed with ever-increasing amounts of herbicide, pesticide and fungicide.

Today, our fields are monocultures of uniform ‘dwarf’ wheat varieties that are only a third of the height of older heritage lines, which can be seen in artwork from earlier centuries. The tall stems of older cereals are matched by their much larger root systems, which allows them to absorb moisture and nutrients from deep below the soil surface. This means they are better at surviving drought, but will also grow very tall and fall over if grown with fertilisers or in rich soil.

Situation normal

The Plant Varieties and Seeds Act (1964) sets the rules that govern the characteristics of the varieties that farmers are permitted to grow in the UK. The Act mandates that, in order for its seed to be sold, a new variety must be genetically ‘distinct, uniform and stable’ – characteristics essential only for varieties developed for use in high-input production systems. Plant Breeder’s Rights legislation gives patent protection for the developer of a new variety so that royalties can be collected on the sale of seed to farmers in order to cover costs and generate profits. Because creating a new modern variety is so expensive, the legislation ensures that plant breeding is done only by large seed companies, and that all new varieties are designed for intensive, high-input, production systems.

John Letts, and a growing number of ‘alternative’ plant breeders, think there is another way of farming that produces the grain we need while minimising the use of fossil fuels and enhancing biodiversity. Truly sustainable farming depends on maximising genetic diversity within the crop as well as biodiversity within the field. This was the driving force behind the creation of the genetically-diverse populations of heritage grains that we now use for our unique distillations.

The difference between growing commercial grain and ancient heritage grains? No one can put it better than John:

“A modern wheat field is the opposite of a natural ecosystem. First, you spray the land to eliminate every species growing there. Then you plant one variety of one species (wheat) that is genetically uniform and do everything you can to keep it that way. You spray pesticides to kill the aphids, herbicides to kill the weeds, and fungicides to prevent disease. You also spray the crop regularly with nitrogen so that it grows as rapidly as possible. All of these chemicals are made from fossil fuels, and more is burned every time the tractor drives up and down the field to spray. Weeds and crop tissues form the bottom of the food chain, and without insects and larger animals, such as birds, have nothing to eat. A modern wheat field is the opposite of a natural ecosystem.”

It is a founding principle of our distillery that grain farming can and should be better; that kind, thoughtful farming methods regenerate the land, encourage biodiversity and make really excellent spirits.

Rye and fields.

And so to Organic

The modern organic farming movement began in Germany in the late 1930s, and triggered the formation of the Soil Association in the UK in 1946. It developed in response to the destruction of soils due to the overuse of tillage and agrichemicals, as well as consumer demand for healthier and more nutritious food. Instead of using artificial fertilisers, herbicides and fungicides, organic farmers use natural methods to increase fertility and minimise pests and diseases, such as mulching, fallowing and rotating field with legumes. Modern cereals do not yield well in soils with ‘natural’ fertility, however, and yields are capped in organic systems because cereals can be grown only once in every 4-5 years of the rotation.

Recreating the natural order

The ancient wheat and rye John discovered in Medieval thatched roofs provided direct evidence of the hardy landraces that once grew in English fields. Thatchers sought out his straw for rethatching works leaving high quality ‘heritage’ grain as a by-product. Guided by the ancient thatch, he collected thousands of samples of wheat and rye from gene banks, traditional farmers and collectors from around the world, and bulked them up on farms and gardens in Buckinghamshire and Oxfordshire.  Most of these samples arrived in packets containing only 25 seeds, which he painstakingly planted, harvested, threshed and bulked up by hand over 15 years. He blended the most suitable varieties together, eventually creating populations that performed well in UK conditions, and which mimicked the diversity that once occurred in traditional landraces. His modern heritage populations are reliable, adaptable, and produce top quality grain for baking and brewing - and since 2014 for distillation.

Although John’s populations can be grown in standard rotational organic systems, he has developed a new way of growing them that can triple grain output from an organic holding while also sequestering carbon, maximising biodiversity, and minimising the use of fossil fuels. At The Oxford Artisan Distillery, we think his method of ‘Restorative Grain Production’ (RGP) is the most sustainable way we know of growing grain. The only thing that leaves his fields after the harvest is the grain. The crop is harvested high on the stem leaving most of the straw standing, the next crop is drilled or broadcast into an understorey of short white clover, and the tall stubble and weeds are then chopped over the seed providing a mulch that slowly releases nutrients as it decays which feeds the new crop. Using this system, grain can be grown in the same field year after year with no reduction in yield or quality. The permanent agro-ecosystem that develops, combined with low levels of nitrogen and high genetic diversity within the crop, minimises problems with pests and diseases. These crops are productive and resilient and perform particularly well in drought. The maximum annual yield is a little lower than in rotational organic system, but because grain is grown every year the overall output is much higher.

Recreating the natural order

Working together

Here at The Oxford Artisan Distillery we want to support research into new ways of growing grain without agri-chemicals and that enhance biodiversity. The climate is changing, and the way most grain is grown today is not sustainable.

With every bottle we sell the demand for John’s grain grows, and more land is turned over to his innovative and restorative production methods. We are proud of our work together, and by using his grains we are demonstrating with actions - and not just words - that cereals can be grown profitably, using environmentally friendly methods.

And not by lucky coincidence but by design, organically farmed ancient heritage grains can be distilled into truly special spirits with the signature maltiness, caramel undertones and silky-smooth mouth feel that make our spirits what they are.
