🍇 Vineyard Ripening and Fermentation Lab: Growing Degree Days, Brix, Acidity and Ethanol Yield

Grow grapes on Blender-built vineyard terraces through a season: growing degree days (base 10 C) drive sugar (Brix) up and acidity down, and you choose the harvest date. Press the grapes, then follow yeast in a cutaway tank: sugar to ethanol (0.511 g/g stoichiometry), temperature-dependent kinetics, heat release and predicted alcohol by volume. Food chemistry and agronomy, with closed-form numerical checks.
