They are very good employees, I took the tremor from them, but I forgot the certificate. I came to get it. It turned out that they are very friendly in their store across the street and without unnecessary reproaches, etc. they help if you ask something.
The shop at the yeast factory is a very interesting place. In addition to the freshest yeast, you can buy everything you need for baking here. Flour, malt, spices, flour additives - all of good quality and at reasonable prices.
