Hello everyone,
I am brewing on a three vessel 30hl brewhouse (mcv, lt, kettle/wp) and I am experiencing low efficiencies. The highest one I got was an all pilsener malt beer (1.036) with 90%. With such a system I would expect at least an efficiency in the mid 90s.
I mash in at 1:3.5 run a step infusion program with a mashout at 77C (mash ph 5.45 at the last brew), transfer into the Lt, start vorlaufing for 15min and once the wort is clear I start collecting. Once I start sparging I cut in 2cm steps from 22cm up to 12cm into the bed. My run off takes about 75min. Last runnings are below 2.0 brix....for a 1.040 beer about 1.8...for a 1.036 I've seen as low as 1.3. We buy our grain pre crushed and it is definitely not a Lt crush. It is very coarse. Do you think a finer grind would help? I am getting quite frustrated because I laid out the Lt for 95% and now we are only getting 90% which results in more grain that is needed and therefore a deeper bed which lowers the efficiency....vicious circle. We are getting quite clear worts with some bits....sometimes more sometimes less. In the wp we lose about 50l.
I think the culprit is the coarse crush. I am thinking about getting some Weyermann malt pre crushed which should be finer due to them crushing for german breweries and therefore Lts whereas the english maltings crush all for mash tuns.
The brewery I worked before got 99% with a wet mill and Lt but this was a Krones kit ;-)
Looking forward to your answers.
