What Is Kbac Drink

Every country in the world has a staple drink, something that is really so unique to them that it embodies the culture as a whole.

In the Baltic and Slavic countries, there is a drink called Kbac(traditional drink) and if you have never heard of it, take a look at what the Kbac drink is.

Kbac or kvass is a traditional fermented rye bread (Russian-style bread) Russian drink. 

It typically has a 1% alcohol level and would be considered non-alcoholic.

Variants can include fermented wheat or barley and a range of fruits or birch sap.

Kbac is used in a lot of traditional dishes and is considered to have some health benefits.

Kbac is very similar to a dark beer or beet kvass stout but with almost no alcohol content.

Apparently, when you leave it in the fridge longer and ferment more, it will become a more alcoholic beverage because of its alcohol content.

The Base

Kbac has a base product that is usually rye bread.

The traditional type of Kbac usually uses dark or black bread or Russian-style bread which tends to give it a richer flavor other than fruit juices. 

You can also use croutons if you cannot find traditional rye or Russian-style bread or brown bread

You can use barley or rye for the lighter varieties, which gives it a less wild taste.

The Flavoring

Several different fruits are used to give Kbac its flavor.

Popular fruits or fruit juices include apples, berries, and raisins for fermentation.

There is always a yeast starter added for the fermentation to start.

If fruits are used, then cane or other sugars are usually left out.

The Procedure

Traditionally Kbac or traditional drink would be made by heating the ingredients until it forms a mash and then subjecting it to heat for several hours.

After it has been heat-treated, it is then diluted with warm water or warm tap water.

The yeast and flavoring are added and then left in a warm place for several days to continue the fermentation process.

It is lautered like beer once ready.

And a portion of the mash is kept as a starter for the next batch.

Kvass is never boiled, and it is this critical aspect that distinguishes it from traditional beers as it contains microorganisms that are responsible for Lacto fermentation.

The darker rye bread kvass tends to be on the more accessible side, while the lighter wheat or barley-based kvass is fruitier, yeasty, and has sweet or brown sugar content.
