Recipe for coffee stout
Preparation:
Important: Thoroughly disinfect the equipment used to make the beer. For this purpose, use e.g. potassium metabisulfite.
1. Remove the yeast from under the lid. Dissolve the contents of the cans (or the concentrate and the glucose) in about 2-3 liters of warm water, stirring constantly.
2. Rehydrate the yeast – pour the yeast into a glass of water at about 25°C, gently stir, and leave for 20-30 minutes.
3. Pour the dissolved concentrate and Coopers extract (or the concentrate and glucose) into the fermentation vessel, top up with water to 20 L. The overall temperature should be about 25°C.
4. Add the rehydrated yeast.
5. Close the fermentation vessel and fit an airlock (half-filled with water). We also recommend measuring the extract content (°Blg).
6. Start fermentation. Carry it out for 7-10 days, until it reaches 0-2°Blg.
7. On the fourth day add 500 ml of brewed coffee to the batch – filter it 3 times to obtain a clear brew.
8. After fermentation, rack the beer into bottles. To each bottle (0.5 L) add 4 g of glucose for refermentation.
9. Cap the beer and set aside for at least 2 weeks.
