I started my first brew today, 1.75 kg coopers wheat beer, 500 grams spray malt wheat & 12 grams brewferm blanche wheat dry yeast, which I proofed.I added 25 litres instead of the instructed 23, will this make a big difference to the finished beer?it's fermenting in a room that is 68 f. I plan on leaving it there for 2 weeks, put it in bottles for another 2 weeks. Any advice on improving on what I'm doing would be appreciated.
