Rub the zest of the lemon with a fine grater and squeeze the lemon. Mash the juniper berries and the cinnamon stick with a wide knife.
Put all other ingredients together with the lemon juice, lemon peel, juniper and cinnamon in a well-sealable glass jar. Pour the double grain over. Let this herbal mixture steep in a dark place for about 10 days and shake occasionally.
Then filter the mixture through a cheesecloth and fill it into glass bottles.
Variant:
Put all ingredients (except the grain) in a saucepan and bring to the boil with approx. 200 ml water. Let the brew simmer for about 5 minutes. Let it cool down overnight. The next day, filter off the herb stock and mix with the grain. Finished!
