Add dried juniper berries to a narrow-necked glass jar, carafe, or jug.

Cover the dried juniper berries with water.

Wrap a layer of cheesecloth around the stop of the glass container. Secure with a loose knot.

Let the juniper berries ferment for one month at room temperature, or until they eventually sink to the bottom of the container.

Serve smreka cold or at room temperature, with or without the addition of sugar and/or lemon.
