What is the maximum utilisation one can expect from your kettle, lets say the hops are fresh(pallets,no loss in alpha) ,plato of around 11 ,pH 5.2 .Evaporation around 7% for a 90 min boil. Our utilisation will generally be around 35%, this can occasionally go up 38% (ie lower wort volume ,better boil),the hops are added at kettle up.
Is it possible to get utilisations of over 40%?.
I have read a lot about first wort hopping,we have found it to have a similar utilisation to that of hops added at kettle up( start of boil),we do notice a different preceived hop flavour. Does anybody else out there have experiances with first wort hop utilisation.
Also what would be the maximum utilisation one would expect in the whirlpool,ie hops added 20 minutes into 30 minute transfer, 15 minute stand then 60 minute transfer.We have utilisation of around 5-8 %.
Any thoughts would be welcome.
Cheers.
