Lonte,I entered the recipe into Beersmith last night and it hit all the specs for a 20L batch size BUT the way my system works is that batch size figure is my post-boil volume. I know from experience I lose around 3L in cooling shrinkage, trub and chiller/tubing. So I will only get ~17L into the fermenter and then following further evaporation and yeast cake losses would likely get ~16L into the keg. For my own recipes I would counter this by going to a 23 or 24L batch size but given the kit's we'll be given are a fixed size I can't do that without dropping the OG. How are others planning to handle this??
In the equipment setup in beersmith, once you know what your losses on your system are, you can edit the Mash tun and Boil kettle losses etc and it will be taken into account for you as Ben suggested.....The 1L or so you lose in the fermentor - well that's goooone :unsure: , but probably the reason Beersom made it a 20L batch...(19L fits in the keg).
I also reckon some of us might struggle to get 75% with all that grain in a system designed for single batches...plus sometimes things don't always go to plan.
I normally get around 70% efficiency in my cylindrical 36L MT when I have more than 7-8kg of grain in there.
Just to make things difficult, I'm still running in a new system (only brewed on it twice) so I'm not exactly sure what efficiency I'll get on the day......exciting isn't it.
We could all get a kg or so of LDME (if we don't have it already) and use it if we don't quite hit the numbers on the day.
That's what I was planning to do anyway - I hope that strategy is OK.
Can't wait.
