Well I threw in the bag of rasberries and will bottle it tomorrow morning.
I took a small sample after only 1.5 days and it was already tasting strong of the fruit so I guess 4 days will be long enough.
Hopefully all the additional sugars are fermented out by then too.
Well I would say this has been a success.
6 days in the bottle and I gave one a go.
Has the right amount of sourness for my taste and the raspberry flavour is there too.
Only thing missing is a bit of head retention but maybe that will come over the next week.
If not I can understand as it was made from a pure second runnings which can be thin.
Anyway a great way to get something different as a second beer from a big grain bill with minimum fuss.
Makes the brew day easier than doing a second full boil and hop schedule.
Next time I will look into adding more fruit and capping the mash for the second runnings with wheat flakes and/or some crystal wheat to help with the head retention.
