Cold soaking: Difference between revisions

Created page with "'''Cold soaking''' is a pre-fermentation winemaking technique in which harvested and destemmed grapes are kept at a low temperature before the start of fermentation to enhance colour, flavour and tannin extraction<ref>Jackson, ''Wine Science: Principles and Applications'', 5th ed., Academic Press, 2020, ISBN 978-0128161180.</ref>. The process is also known as pre-fermentation maceration. == Background == The practice of cold soaki..."

The main objective of cold soaking is to enhance colour stability, particularly in lighter-skinned varieties, and to extract aromatic compounds without excessive tannin<ref>WineMaker Magazine, “Cold Soak Explained”, winemakermag.com.</ref>. It can promote the development of more intense fruit character and a rounder mouthfeel, especially in wines made from Pinot noir, Merlot and Syrah.

However, the technique requires careful hygiene and temperature control to prevent spoilage organisms from developing during the soak<ref>Jackson, ''Wine Science: Principles and Applications'', 5th ed., Academic Press, 2020, ISBN 978-0128161180.</ref>. Some winemakers opt for a shorter soak or use sulphur dioxide to mitigate microbial risks.
