BD Preparations

Nine numbered biodynamic preparations (500–508) made from cow manure, silica, and six medicinal plants, applied in tiny doses to soil and vines on a fixed schedule.

Concept

Biodynamics

An agricultural system developed by Rudolf Steiner in 1924 that treats the farm as a single living organism, prescribing specific preparations and a cosmic-rhythm calendar.

Concept

Demeter Certification

The international biodynamic certification, founded in Germany in 1928. Stricter than organic and stricter than Demeter USA, with whole-farm rules and mandatory preparations.

Technique

Lunar Calendar (Maria Thun)

A biodynamic planting and tasting calendar that classifies each day as root, leaf, flower, or fruit based on the moon's sidereal position against the zodiac.

Concept

Natural wine

Wine from organically or biodynamically farmed grapes, fermented with indigenous yeasts, with no or minimal sulphur added and without fining or filtration.

Style

Orange wine

White wine that turns amber to orange through extended skin maceration and develops tannin; the typical outcome of several weeks to months of skin contact.

Concept

Organic vs Biodynamic

Organic farming defines what you avoid (synthetic chemicals). Biodynamic farming adds a fixed set of preparations, a cosmic calendar, and whole-farm logic on top of organic.

Style

Pét-nat

Sparkling wine bottled before primary fermentation finishes; the remaining sugar ferments inside the bottle and produces the bubbles via the méthode ancestrale.

Concept

Rudolf Steiner

Austrian philosopher (1861–1925) whose 1924 Koberwitz lectures founded biodynamic agriculture, the framework behind Demeter certification and biodynamic wine.

Technique

Sans soufre

Wine made without any added sulphur dioxide during vinification or bottling; small amounts always remain as a natural by-product of fermentation.

Technique

Skin contact

Vinification technique where white grapes macerate together with their skins for days to months, adding tannin, colour and texture to white wine.

Concept

Vin vivant

Living wine: unfiltered, unpasteurised wine in which yeast and bacteria remain active after bottling, without additives that suppress microbial evolution.
