What materials are typically used for inert vessels in spirit storage?

Inert vessels used for spirit storage are essential for ensuring that the flavors and characteristics of the spirit are preserved without any interaction that can alter its composition. Stainless steel and glass are commonly used materials for this purpose.

Stainless steel is non-reactive, meaning it doesn’t impart any flavors or contaminants to the spirits, which allows for clean storage. It is also durable, easy to clean, and resistant to corrosion, making it a practical choice for both short-term and long-term storage. Glass, similarly, is inert and doesn’t affect the taste of spirits. It also provides a barrier to oxygen and light, which can be detrimental to spirit quality.

In contrast, other materials such as wood or concrete may allow for undesirable interactions that can change the profile of the spirit. Wood, while often used for aging certain spirits like whiskey, is not considered inert as it can impart flavors and oxidation over time. Concrete can also react and is not commonly used for longer-term storage of high-quality spirits. Similarly, copper, while traditionally used in distillation, is not inert for storage as it can catalyze unwanted reactions.

Thus, stainless steel or glass is the optimal choice for inert vessels in spirit storage.
