Wine yeast home use
Wine yeast (wild) – living cells of yeast fungus, they are used to make wines, which, through their fermentation, convert sugar into alcohol and give the drink a special taste.
Many winemakers believe that it is the wild yeast that gives the wine good quality and special aroma.
Wine yeast is added to make homemade wine
To prepare wine yeast, it is necessary to prepare the fruits, calculate the required amount of sugar, and create conditions for the fermentation process.
Homemade wine yeast is divided into several types, has different taste properties and affects the characteristics of the wine. Fruits are suitable for sourdough:
- grapes;
- strawberries;
- raspberries;
- plums;
- rose hips;
- gooseberry;
- currants.
The berries should be picked in the morning, in dry weather, and not washed. Mash two cups of fruits into gruel, add 0,5 cups of sugar, pour 250 g of purified water. Mix everything thoroughly, pour into a bottle, plug with cotton wool. Place in a dark, warm room for 3-5 days, until the yeast works, and a characteristic sediment forms at the bottom of the bottle.
The yeast bacteria required for fermentation are found on the surface of the fruit and should not be washed.
You can use figs or raisins for sourdough. Boil sugar syrup: from a glass of water and 100 g of sugar, add 200 g of unwashed raisins, pour the resulting mixture into a bottle and cork with a cotton wool stopper. Leave to ferment for a few days.
The formation of foam, fizzing and a slightly sour smell indicates that the starter is ready to use. The resulting juice is filtered through a gauze filter and used for making wine for 8-10 days, as it has a short shelf life.
The wine yeast sediment is useful for using as a starter raw material for the next batch of homemade wine. It contains the necessary fungi for making dry yeast, which have a longer shelf life.
Drain as much of the liquid as possible from the remaining wine sediment and spread it in a thin layer on a baking sheet. It is necessary to dry in the sun or on a stove below 30 degrees so that the yeast does not die. Scrape off the resulting dry mass and put in a paper bag. Such a powder is stored for several years.
To prepare the starter culture, you should use a teaspoon of dry yeast in a bottle, pour a glass of warm water, add 50 g of sugar. Plug the bottle with a tight cotton cork, let it ferment for 3-4 days. When foam and sizzle forms, the starter is ready for use.
To increase the activity of the yeast, add a few dried fruits (prunes, dried apricots) or a spoonful of raisins to the starter culture
Brewing alcoholic beverages using wild yeast facilitates the wine making process. Homemade wine yeast will give the drink a special soft taste and delicate aroma of sweet berries.
