Bread kvass with malt. Kvass from rye malt

By color, taste and aroma, properly made homemade kvass from malt cannot be distinguished from natural store-bought drinks prepared in accordance with GOST. We will look at traditional technology that has been proven for decades.

Theory. Kvass made from fermented rye malt is considered classic, but in the proposed recipe, you can use any other malt in the same proportions, for example, barley or wheat, although the taste will change. Next, let's look at the difference between fermented and unfermented malt.

In the preparation of spirits, we use unfermented malt, which we split into sugar, and then through fermentation we process it into alcohol. But for kvass, it is better to take a more aromatic fermented malt used in bread baking (after sprouting and drying, the grains undergo additional heat treatment at 50-70 ° C in an airless chamber).


Ground rye fermented malt

Fermented malt does not participate in fermentation, since high temperature destroys the enzymes in the grains that are responsible for the breakdown of starch into simple sugars, but it makes kvass more aromatic and tastier. To saturate the drink with carbon dioxide, added beet sugar will ferment for several hours.

The minimum amount of sugar (according to the recipe) to obtain carbon dioxide is 100 grams, then be guided by taste. The drink can be further sweetened before bottling. In extreme cases, instead of dry yeast, pressed ones are suitable, but they can give kvass an unpleasant yeasty taste, so it’s better to take dry ones.

After the first preparation, a sediment will remain, which is called "thickness" and is a natural leaven that replaces the yeast. To get kvass from malt without yeast, during the next preparation, add a handful of kvass from the first batch.

Ingredients:

  • ground rye fermented malt - 50-80 grams (a little more than half a glass);
  • water - 2 liters;
  • sugar - 100-150 grams;
  • dry yeast (baking) - 5 grams (only for the first batch).

Recipe for kvass from malt

1. Bring water to a boil, remove from stove, cool to 50°C.

2. Slowly add the malt to the hot water, stirring constantly to avoid lumps. You should get a homogeneous mixture, resembling choux pastry. Leave to infuse for 2-3 hours.

3. During the first preparation (if there is no starter), after the kvass wort has cooled to 26-28°C, pour 100 ml of liquid into a glass separately and dilute the yeast in it according to the instructions on the package. If the temperature is above 30°C, the yeast may die.

4. Add diluted yeast or a handful of sourdough (“thick”) to the wort, add sugar.

5. Stir until the sugar is completely dissolved. Cover loosely with a lid, leave for 8 hours to ferment in a dark place (cover) at room temperature (18-26°C).

6. Filter malt kvass through 2-3 layers of gauze.

The sediment can be collected in a separate container and stored in the refrigerator for no more than a day. This is a natural starter that replaces dry yeast in the following servings of the drink.


Thick at the bottom of the jar - yeast for the next batches of kvass

7. Try a drink. Add sugar to taste if desired.

8. Pour kvass into storage containers - plastic or glass bottles, jars. Leave 3-5 cm of free space in each container. Close hermetically.

9. Before use, put the bottles in a refrigerator or cellar at a temperature of 2-10°C for at least 3-4 hours to cool and carbonate (carbonate).

The shelf life of kvass from malt is up to 5 days. The drink is obtained non-alcoholic or with a minimum alcohol content (up to 0.5%).

In the summer heat there is nothing better than a glass of cool. It will quench thirst, help the body endure the high temperature of the environment and give energy.

Interesting: there is evidence of the ability of kvass to stimulate the immune system, increasing the body's resistance to viruses and infections!

At the same time, homemade is definitely more useful than purchased. Let's try to master the intricacies of making kvass from malt by doing "production" at home.

Malt is sprouted grains of various cereals: barley, wheat, oats, buckwheat, rye and even corn. It is in the sprout - the embryo of the future harvest that all strength and energy of the seed. Scientific studies have shown that the percentage of vitamins increases several times compared to what was in unsprouted grain.

This is especially true for vitamins PP, group B, as well as E, which can only be obtained from sprouted grain, it is not in a sleeping grain.

Everyone has heard about the benefits of eating sprouted grains. But all the power, energy, healing properties are transferred to both malt and drinks made from it, especially “live”, not pasteurized or distilled. Kvass is the best of them, it has a positive effect on many body functions.

Which one should you buy?

On sale you can find various types of malt. But you should know that not all of them are suitable for kvass:

  • barley- an excellent raw material for beer;
  • wheat also used in brewing and;
  • corn we have a less popular, but also found on sale, raw materials for (corn whiskey);
  • oat used to create Chateau beer or in mixtures with other types of malt;
  • buckwheat- exotic for us, called Chateau Buckwith. Also used alone or in a mixture with other species is used in;
  • rye has a wide range of applications: as an additive to the wort for whiskey, beer, in bakery. It is also considered the best for kvass. It provides a wonderful dark color, sweetness in aroma, refreshing taste.

Peculiarities. We will not argue that only rye malt is suitable for kvass. You can experiment (especially if there are other types). But still take as a basis rye.

Recipe at home

Making malt at home takes a lot of time and requires precise compliance with the requirements at every stage. But if there is such a desire, then there is nothing particularly difficult in this.

Attention. It is unlikely that you will be able to get a fermented product at home.

This is a verified and robotic production process, in which already germinated grain ( green malt) before drying, they warm up for a long time with exact observance of the temperature and time of each stage.

Homemade unfermented malt will produce white () kvass. If you want to paint over it, add a couple of handfuls of crackers from well-fried rye bread to the wort. Note: the taste will also change!

The most delicious and healthy "live" rye kvass in the old days was prepared from rye malt. But the process of preparing such kvass was quite long and laborious. To obtain malt, rye grain was first sieved and thoroughly washed. Then it was soaked until it germinated. After that, the germinated rye grain was dried, steamed, ground - and only after all these procedures was the rye malt for kvass ready. But in Russia there was also an easier and faster way to make rye kvass - from dried rye bread.

Here we have collected for you the most interesting recipes for making rye kvass from malt, rye bread and rye flour.

Kvass recipes based on rye malt

Due to the fact that it is usually very problematic to buy rye malt for kvass in any store, we suggest you prepare the malt yourself as follows:

It is necessary to sift and wash the grains of rye and soak them in an enamel pan for 25-30 hours. Every 7-10 hours, the grains should change the water, leaving them periodically without water for 2-3 hours (this is necessary for the access of oxygen, which activates various biological processes in rye grain). After soaking, rye should be placed in low enameled dishes (or low plastic trays) and germinated for 3.5 days (it is best to germinate rye grain at a temperature of 20 - 22 ° C.). During germination, rye grains must be periodically moistened and ted. For 2-3 days, roots should appear in the grains. Germination can be completed on the 3rd-4th day, when the length of the roots reaches 0.75 of the size of the grain itself. The rye malt obtained in this way can be stored for no more than 2-3 days. But you can also prepare malt for a longer period. To do this, it must be dried at a temperature of 60-70 degrees for 24 hours, then it must be cleaned of sprouts and ground. Dried and crushed malt is best stored in a closed container in a cool place.

In some kvass recipes below, in addition to rye malt, barley malt is also used. It is prepared in the same way as rye, but there are some differences. In the manufacture of barley malt, the soaking of barley grains should last 50-60 hours, the time of germination at room temperature of barley grains is 6-7 days. In addition, at the end of germination, barley grain sprouts should not exceed 1.5-2 the size of the barley grain itself.

Recipe for kvass from fermented rye malt

For the manufacture of fragrant kvass at home, fermented malt is taken (the one whose grains have been germinated, dried and heat-treated at a temperature of about 60 degrees). True, for a drink with fermented malt, yeast will also be required, since such malt has lost its fermentation properties due to high temperature. However, it is from such malt that the most aromatic and tasty drink is obtained. You can buy fermented rye malt at a retail price of about 150-250 rubles per kilogram.

Ingredients

  • Malt - 100 g;
  • Sugar - 200 g;
  • Water - 4 l;
  • Dry yeast (for baking) - 10 g.

Cooking process



If desired, ready-made kvass can be made sweeter by adding a certain amount of sugar to it at the end of fermentation. Such a drink is stored in a refrigerator or cellar at a temperature not exceeding 10-15 degrees for 5 days.

According to the specified recipe, the first sourdough for homemade kvass is made. For the second and subsequent times, you can make a drink in which kvass sediment is used instead of yeast. It is added at the stage when the malt-water mixture cools down to a temperature of about 25-28 degrees, it is thoroughly mixed, sugar is added and set for fermentation, repeating the same steps as in the indicated recipe.

Recipe for kvass from unfermented malt

If desired, you can make kvass from malt that has not undergone heat treatment. The cost of unfermented and fermented malt is about the same.

Ingredients

  • Malt (unfermented ground) - 100 g;
  • Flour (wheat) - 100 g;
  • Water - 3 l;
  • Raisins - a small handful (20-25 pieces).

Cooking process


This recipe is closest to the old, traditional ones. Traditionally, malt, berries and fruits were used to make kvass. There were no other sources of sugar, because refined sugar appeared in Russia only in the 17th century, and it was not cheap. Later, in cities where access to malt was limited, bread was used in the preparation of kvass as a substitute for malt. So gradually bread kvass replaced malt kvass as a traditional drink.

Ingredients for "Traditional Malt Kvass":

  • (non-fermented wheat (700g) and fermented rye (300g)) - 1000 g
  • 5 l

Cooking time: 1440 minutes

Servings: 10

Recipe "Traditional malt kvass":

Before preparing kvass, it is necessary to prepare the sourdough. I will not publish the sourdough recipe, there are a lot of them on the site. You can use any. For example: "Sourdough for bread "Eternal"" by a-lesa cook or "Bread kvass and eternal sourdough" from Mary Stone
Any malt can be used in this recipe: barley, wheat, rye, buckwheat, etc.
For this kvass, you will need 2 types of malt - white (non-fermented) for saccharification and black (fermented) for taste and color.
I have white - wheat and black - rye.

Grind malt. Pour into a saucepan with a thick bottom. To fill with water.

Let's start mashing the wort.
With continuous stirring, constantly monitoring the temperature with a thermometer, heat the wort to 72 gr. WITH

Temperature control is extremely important. After all, this recipe does not use additional sugar, except for the sugars contained in the malt starch. Therefore, it is necessary to properly activate the enzymes that break down starch into simple sugars. Saccharification begins already at 64 gr. C. When the temperature exceeds 75 gr. With enzymes "cooked" and will not be able to work.

When the temperature reaches 72 gr. C, remove the pan from the burner, close the lid, wrap it in blankets for a couple of hours (most conveniently at night).

If everything is done correctly, at the end of the mash, you can immediately see that the wort has become much thinner.

You can verify the complete saccharification of the wort by conducting an iodine test. To do this, pour a teaspoon of wort on a plate and drop iodine on it. With complete saccharification, the color of iodine will not change. If the wort contains starch, the iodine will turn blue or black.
In this case, the wort will need to be heated again to 72g. C and wrap for a couple of hours.
