In what type of vessels is grappa typically matured?

Grappa is typically not matured in wood barrels, as its production process generally involves distilling grape pomace and then aging it in inert vessels such as stainless steel tanks or glass containers. The purpose of using inert vessels is to preserve the fresh and fruity characteristics of the grappa without introducing additional flavors or tannins that come from wood aging.

While some artisanal and premium grappas may spend a short time in wooden barrels for additional complexity, the standard practice focuses on maintaining the spirit’s clarity and the natural flavors of the grapes. Inert vessels prevent any interaction that could alter the original taste profile of the grappa, which is key to its identity.

Thus, the aging process for grappa emphasizes freshness and purity, making inert vessels the most suitable choice for its maturation.
