I stated breing in April and seem to be getting on well with Ale's, no probs. But I have made two Porter's and I am getting high FGs. the first I made back in May , and it was a hot weekend, and the fermentation only lasted 24 hours. So I put the high FG down to that. However, I have just made a Porter using T58 yeast. OG was 1.059, but when I racked to secondary after 1 week it was only 1.026. Any ideas? Should I add two packets of yeast for Porters, do they need more?? Or, it is just a slower fermentation and hopefully I will have a lower FG when I bottle.
