How long should bilberries infuse in vodka?

Expanded Explanation

Bilberries usually infuse well in vodka within two to four weeks. Their color extracts quickly, often within the first few days, while the fuller fruit flavor develops more slowly. A shorter infusion gives brighter acidity and fresher berry notes, while a longer infusion gives deeper color and more rounded intensity.

For most homemade bilberry liqueurs, three weeks is a reliable starting point. Taste the infusion after fourteen days, then continue only if the flavor still feels thin. If the berries are crushed heavily or very ripe, extraction may happen faster and the infusion may need less time.

Leaving bilberries in vodka too long can pull out excessive skin dryness, seed bitterness, or earthy notes. Once the flavor is strong and balanced, strain the fruit and filter the liquid. Sweetening after straining gives better control over the final balance and helps avoid covering mistakes with too much sugar.
