I'm bending towards doing a 14.5 Litre batch of this AG for my first AG ever.. Now, reading into it, 52 litres for the original recipe,
1) how many litres of water should I use to start mashing?
3kg of grain @ 3L / Kg would be 9 liters. Asuming you will be mashing in an esky add you 9 liters @ 71 to 72 deg c for a 65 deg mash.
Sparge with 15 liters of water to get your final volume of 14.5 liters with a 60 min boil accounting for 6L/kg evaporation rate. If you come up a bit short after the boil you can top it up in the end.
2) How much yeast do I need? 1 Packet of US-05 rehydrated or is that too much? I have some washed US05 saved up from the last yeast cake, ~30 ml I think.. I can always try stepping that one up
one pack of dry US-05 will shit it in! No need to rehydrate it....... just sprinkle it in the fermenter and rack your cooled beer onto it.
Your saved yeast should be fine too, but prove it first... make sure its kickin!
3) Reduced to 14.5 Litres, I would need exactly 25.1 grams of each hop as per recipe. I bet the hops I get in the shop are bound to have different Alpha acid%, Now, should I only adjust the 45 minute and 20 minute additions for the aa% difference or should I change the amount of 0 minute additions as well?

Sorry to ask such noob questions in advance, trying to clear up some of my unasked questions here. And thanks in advance
PS: I plan to tweak the batch size (upto 17-18 litres max) depending on what figure lets me use entire hop packets in one go.
