hot break come and gone. 1st hops in.
Wez, i think this is why i've been struggling to work out my efficiency you know. cos what's been coming out of the boiler has always been about 15-20L, but usually way above the 1.050 mark. so i've been having to top up with water to bring to volume and get the OG down. TBH i've always hit my target OG, mostly because i've had that control at the end where i just add water till i reach my gravity hehe. cheating but hey.
ok well next time i'm going to run it down to .995 (uncorrected) leaving it still above tanin extraction level and see how that turns out after the boil at least then i've got a clear idea of my efficiency without having to try to work it because i've added water etc
