Description

Having a nice fruity sour beer is lovely but with traditional method such as kettle souring or sour aging it can be a laborious and time consuming process.

However using Lallemand’s WILDBREW Philly Sour Pitch yeast  you can make the process a lot simpler. Basically as it ferments there is a production of lactic acid which sours the beer, and the sour pitch utilises free sugars well to produce this lactic acid.

Now here comes the really lazy bit, Lowicz Raspberry Syrup  is basically just fruit concentrate and sugar, so rather than faff about with fruit pulp I simply stir 2 bottles in at the end of the boil.

The syrup is 78% sugar so 2 400ml bottles will give you about 624g of sugar in the recipe, plenty for creating a good level of sourness.

If you enjoy this with the Raspberry Syrup why not try it with other flavours!

Comments:

Philly sour is a slow fermenting yeast, which can be fermented at 27°C with no adverse effects, to speed it up. The free sugars in the Lowicz Raspberry will help produce a good level of sourness. You can find these syrups in most super markets and Polish shops.
