Yeast is a micro-organism that promotes fermentation. It is a key component in the production of alcoholic beverages such as beer and wine. That doesn't mean there isn't a way around the addition of yeast. Just collect about 1.36 kg (3 lbs) of fresh blackberries and follow a series of steps to make a delicious red wine at home that won't need yeast to bring out the alcoholic qualities you seek.
Wash the blackberries to remove any dirt, and place them in a large bowl.
Boil 4.5 litres (1 gallon) of water in a pot.
Pour the boiling water over the berries. Stir with a wooden spoon, then cover the bowl with a towel.
Set the bowl aside for 10 days in a dry place at room temperature.
Remove the towel after 10 days and gently peel off and discard the mould that will have formed on top of the berry juice.
Place muslin or a cheesecloth over the bowl. Pour the juice through the cloth into another bowl to strain the liquid.
Add the sugar to the strained blackberry juice and stir it for at least one minute.
Pour this liquid into old wine bottles and cork them.
Wait at least three months to uncork the bottles and sample the yeast-free wine.
Wait at least six months before sampling the wine.
During the initial soak, add citrus peels, clove or even cinnamon to imbue your wine with unique flavours.
