Just taken a hydro reading of the brew number 3, English IPA and again just like brew no 2, the Porter, i'm 0.7% over the predicted ABV. I'm guessing this is due to not topping up the wort with water to the predicted volume I had in my calculator spreadsheet?
I was expecting 9.61L into the fermenter but actually got 8L. Does that difference sound about right to raise the ABV by around 0.7% ?
Should I mess with my method? I don't mind a stronger beer! My OG always seems higher than the recipe and FG about spot on.
I think 0.7% is less of an increase than the reduced volume should provide, without doing any calculations.
I think it's a good idea to work towards getting what you aim for. Then you will gradually learn to make beers exactly how you want them to be. Increase your water next time. Extra sparge water, if you sparge. About 1.5 litres for a similar grain bill if the target volume is the same. If you like a stronger beer, add more base malt!
