1 x Wine Yeast Nutrient DAP 10g: An essential component supporting yeast during the fermentation of wine. 1 x Oak Chips Sachet (20g): Medium toasted French oak chips adding notes of caramel, toffee, vanilla, and sweetness to the wine. Wine Yeast Nutrient DAP is an indispensable addition supporting yeast in achieving full and rapid fermentation. Recommended for all fermentation processes, it provides yeast with the necessary source of nitrogen. Grape must often lacks sufficient nitrogen, which can lead to slow fermentation and the formation of unwanted fusel alcohols, negatively impacting the taste of the finished wine.
