What You Need to Know
Concentrated grape must undergoes Maillard reactions and enzymatic breakdown of sugars (invertase activity) while acetic acid bacteria (Acetobacter spp.) and wood-derived compounds create complex flavor matrices. Evaporation (up to 10% annual 'angel's share') increases viscosity.
Develops syrupy texture and balanced sweet-sour profile with layered umami characteristics, transforming simple grape must into a premium finishing ingredient.
