Beer recipe - Raspberry Sour Ale
| ABV | 4.5% | Bitterness* | 8 IBU |
Description
Sour beer produced by the technique of "kettle souring" where bacteria is added to filtered wort, before boiling and any hops addition, to trigger acidification of the wort through the production of lactic acid. This beer has a light body with a clean acidity in balance with the sweetness, flavour, and aromas of raspberry. With a moderate-high carbonation, this refreshing beer is a great summer drink.

*The bitterness depends on the alpha acid content of hops, boiling conditions and other parameters.

Step 4: Fermentation and Maturation
Cool down the wort to 18°C and pitch the yeast. Ferment at 18°C for 1 day then rise to 22°C. After 4 days, add crushed raspberry. Once the fermentation is done (FG reached and off flavours removed – about 7 days), drop the temperature to 8°C and rest for 1 day and then harvest the yeast. Drop the temperature to 2°C and rest for 7 days. Please note that the ABV can be affected by the raspberry addition due to its volume and sugar level.
