Biodynamic viticulture is increasingly associated with some of Bourgogne’s most ambitious domaines. It builds on many principles of organic farming but takes them further, viewing the vineyard as a complete, living ecosystem rather than simply a place where grapes are grown. It is also one of the more debated approaches to viticulture. Some practices have an obvious agricultural rationale; others are based on ideas that are difficult to demonstrate scientifically. Understanding that distinction makes biodynamics much more interesting.
What is biodynamic viticulture?
Biodynamic agriculture developed from ideas presented by the Austrian philosopher Rudolf Steiner in 1924. In the vineyard, synthetic herbicides, pesticides and fertilisers are avoided, much as they are in organic viticulture. Growers instead focus on soil life, biodiversity, composting and maintaining healthy vines with as little external intervention as possible. The vineyard is regarded as an interconnected system involving vines, soil, microorganisms, plants, insects and the surrounding environment. For many Bourgogne growers, this attention to the health of the vineyard is the most important aspect of biodynamics.
Preparations and the calendar
Biodynamics also introduces practices not found in standard organic farming. Special biodynamic preparations are applied to vineyards or compost. One of the best known is preparation 500, made from cow manure that is fermented in a cow horn buried in the soil before being diluted, stirred — or dynamised — in water and sprayed over the vineyard. Another preparation, 501, uses finely ground quartz. Biodynamic growers may also time vineyard activities according to lunar and astronomical calendars, distinguishing between root, leaf, flower and fruit days. These practices are an important part of traditional biodynamic philosophy, although their claimed effects are scientifically controversial and evidence for some of them remains limited.
Why biodynamics in Bourgogne?
Bourgogne is particularly suited to the philosophy behind biodynamics because growers already place enormous importance on individual vineyard sites. A producer farming tiny parcels wants healthy soils, deep root systems and balanced vines. Supporters of biodynamics argue that reducing chemical inputs and encouraging active soils allows vineyards to express their individual character more clearly. Whether biodynamics itself produces greater terroir expression is difficult to prove. What is clear is that practicing it generally requires intensive observation and hands-on vineyard work. And in Bourgogne, where tiny differences between vineyards matter enormously, that attention can be valuable.
Is biodynamic wine certified?
It can be. Organisations such as Demeter and Biodyvin provide biodynamic certification. Their requirements go beyond standard organic certification and cover both vineyard practices and, to varying degrees, winemaking. However, not every domaine using biodynamic methods seeks certification. Some follow selected practices, others farm entirely biodynamically but prefer not to place a certification mark on the bottle. As always, the producer matters.
Does biodynamic mean better wine?
No farming method guarantees a great bottle. Some of Bourgogne’s finest wines come from biodynamically farmed vineyards, but that does not prove that biodynamics alone makes them better. These wines are also produced by highly skilled growers working exceptional vineyards, often with extremely meticulous viticulture. Conversely, biodynamic certification cannot compensate for poor vineyard work or winemaking. It is therefore better understood as a farming philosophy rather than a quality classification.
Beyond the label
Organic and biodynamic viticulture are closely related, but they are not interchangeable. Organic farming provides a regulated framework restricting synthetic inputs. Biodynamics starts with similar principles and adds a broader philosophy involving preparations, soil vitality and natural cycles. Not every element of biodynamics has strong scientific support. Yet many of the practical ideas surrounding healthier soils, biodiversity, careful observation and reduced dependence on synthetic treatments have become increasingly influential in Bourgogne. Ultimately, biodynamic tells you something about how a grower chooses to work. Whether those choices have produced a great Bourgogne can only be answered by opening the bottle.
