In viticulture, two separate processes are involved, growing the grapes, and making the wine.
Grapes: The same rules of growing biodynamic grapes are followed as for growing organic grapes. A biodynamic wine-grower must also treat the vines and the soil with biodynamically produced compost [LINK TO WHICH BLOG POST?] and use biodynamic field sprays.
Wine: To make biodynamic wine, the grapes must be fermented into wine according to Demeter’s (biodynamic) processing standards. These are similar but stricter than those for organic, and focus on encouraging winemakers to make their wines as naturally as possible and with minimal environmental impact (water and energy use etc).
For example, less added sugar and fewer additives are permitted; and only natural yeasts are allowed to ferment the wine.
A vineyard that is certified Demeter (biodynamic) will also automatically be a certified organic vineyard. But though the grapes will be certified biodynamic, the wines produced from Demeter vineyards may be certified biodynamic or organic, depending on whether they have been produced to Demeter or to organic processing standards.
In the UK, we are fortunate enough to have 7 Demeter biodynamic certified vineyards,including well known award winning vineyards; Albury in Hampshire, Sedlecombe in East Sussex, and Ancre Hill Estates in Monmouthshire.

Many are open to visitors, hold regular events, and in some cases have online shops.
