Just out of interest, is there anyone who wants an Amber Ale instead of an Amber IPA?
The thought occurred to me that we could be over engineering this to cater for 2 options when maybe everyone is happy with the single option.
In terms of output volume (the original/primary reason we went down the dual path) we could still boost the OG with some dex and DME in the boil, so the mash size isn't a limiting factor.
So we still make the beer like an Amber Ale, then add in 5% dex & 5% DME. This takes a, say, 5.5% Amber to a 6.3% Amber (eg: 5kg grain per 22L cube, at 75% extraction eff).
I'm just thinking that if everyone wants the IPA version it might be easier to chuck the powders into the kettle rather than everybody have to do it individually later on. Also makes the hops a little more straightforward.
If there's still some who prefer an Amber rather than the IPA then that's fine and we continue on with that strategy. Just thought I'd check were not over complicating things.
