Description

Beverage Maker{Beer Maker}

The present invention relates to a beer production apparatus, and more particularly, to a beer production apparatus for producing beer by fermenting beer materials.

Beer is an alcoholic beverage made from malt (malt) made from sprouting barley, filtered, added hops, and fermented with yeast.

Consumers can purchase ready-made products manufactured and sold by beer makers, or they can make house beer (or craft beer) made by directly fermenting beer ingredients at home or in a bar.

House beer can be manufactured in a variety of types rather than ready-made products, and can be manufactured according to consumer tastes.

The material for beer production may be water, malt, hops, yeast, flavor additives, and the like.

Yeast can be called yeast and can be added to the malt to ferment the malt and help produce alcohol and carbonic acid.

Flavor additives are additives that enhance the taste of beer, such as fruit, syrup, or vanilla beans.

Typically, house beer may include a total of three steps of a wort production step, a fermentation step, and a maturation step, and it may take 2 to 3 weeks from the wort production step to the maturation step.

For house beer, it is important to maintain the optimum temperature during the fermentation stage, and the easier it is to manufacture, the more convenient the user can be.

Recently, a beer manufacturing apparatus capable of easily manufacturing house beer at home or a bar is gradually being used, and it is preferable that such a beer manufacturing apparatus is configured to be convenient to use while maintaining the optimum temperature for beer fermentation. .
