The fermentation vessel material significantly affects heat transfer and wine flavor development. Stainless steel tanks are known for their excellent heat transfer properties. They quickly conduct heat away from the fermenting must, allowing for precise temperature control. This is crucial for maintaining optimal yeast activity and preventing excessive temperature spikes that can lead to stuck fermentations or the production of undesirable aroma compounds. Because stainless steel is non-porous and inert, it does not impart any flavors to the wine, allowing the grape....
