Hi all,
I’m currently trying to get my head around Beersmith, and how to adapt a recipe to my equipment. I’ve followed drsmurto’s guide to setting it up, but I’m having trouble understanding how it handles some of the volume variables.
It seems that when different values are entered into the deadspace field in the equipment set up, the only thing that changes is the volume of sparge water. For example: a 22 L batch made with a lauter tun deadspace of 1 litre and 4 kg of malt requires 30.19 L of water in total, of which 20.99 is to sparge with. The same recipe with 7 litres of deadspace requires a total 36.19 L, 26.99 to sparge. But, this 6 litre difference makes no difference to the predicted pre-boil SG, which comes out as 1036 in both cases (using the default efficiency of 75%).
That doesn’t seem right to me… surely that extra 6 L of water dilutes the wort and affects the SG, and presumably the efficiency?
Once I’ve figured that out, I’m considering doing TL’s latest iteration of his SNPA clone for my first attempt at AG: viewtopic.php?f=11&t=4839&start=160
TL has achieved 83% efficiency, hitting an SG of 1050. I’m assuming that if I hit 70% efficiency on my first attempt, I just need to up the grain quantities, keeping the proportions the same, until Beersmith tells me I’ll hit the right pre-boil SG. Is that right?
Cheers all,
Matt
