Biodynamic wines are wines made employing the biodynamic methods both to grow the fruit and during the post-harvest processing. Biodynamic wine production uses organic farming methods (e.g., employing compost as fertilizer and avoiding most pesticides) while also employing soil supplements prepared according to Rudolf Steiner's formulas, following a planting calendar that depends upon ...

Brettanomyces produces an array of metabolites when growing in wine, some of which are volatile phenolic compounds. Together, these compounds are often referred to as "Brettanomyces character", and are often described as "antiseptic" or "barnyard" type aromas. Brettanomyces is a significant contributor to wine faults within the wine industry. [75]
Tannins are mainly physically located in the vacuoles or surface wax of plants. These storage sites keep tannins active against plant predators, but also keep some tannins from affecting plant metabolism while the plant tissue is alive. Tannins are classified as ergastic substances, i.e., non-protoplasm materials found in cells.

Vines store sugar in grapes through ...
