Should bilberries be frozen before infusion?

Expanded Explanation

Freezing bilberries before infusion can be helpful, especially when the berries are firm or freshly picked. Freezing breaks some of the fruit cell structure, so the berries release juice, color, and flavor more easily once they are covered with alcohol. This can improve extraction without heavy crushing.

Frozen bilberries are also practical because the fruit is seasonal and delicate. They can be stored until enough berries are available for a full batch. After thawing, they become softer and juicier, so they should be handled gently and added to the jar with any released juice.

Freezing is not required, but it is useful. Fresh ripe bilberries can be infused directly if they are clean and flavorful. Avoid repeatedly freezing and thawing them, as this can damage texture and create dull flavors. Whether fresh or frozen, remove leaves, stems, insects, and spoiled berries before maceration.
