I want to have a crack at this method but I'm a bit sketchy on calculating gravity's.
The idea was to start with a simple IPA made up of Pilsner, crystal and perhaps a little Rye, then from the second running's, an APA of sorts, then basing the hop additions on whatever the OG winds up as.
The batch size around 25L for the first running's.
So, with that in mind, can someone give me an idea of what numbers I need to hit on the first batch in order to to get around the 4-4.5% mark from the second? or at least how to calculate it.
I really don't want to go with LME or sugar additions to prop up a flaccid gravity from the second running's, nothing wrong with it of course, just not what trying to achieve.
For the sake of simplicity, lets work on two 25L batches.
My rig is about as simple as I am, but now I use a 50L keg to mash with rather than my trusty 40L Coleman. So big (er) grain bills and step mashing are no problem.
Love
Dave
