Centennial AIPA

[Underground Joe]

I've used this this grain bill before but with different hops. I'm thinking of putting a silly amount of hops in to produce something special. I want the IBU to be around what I have it as, but anyone has suggestions on how to better waste 240g of centennial please let me know.

And what grain bill might that be?

Looks good to me. Personally I would cut the crystal down to 250g or 350 at most but thats just my taste and as you say you have used that grain bill before.

Just one thing - your boil volume says 27.5l for a 25l brew length. Is that post or pre-boil? If its pre-boil I would have thought you will lose more than that in evaporation alone let alone to the hops, trub and boiler deadspace...

That is something I'm still learning and trying to figure out. Obviously my equipment will differ slightly from yours but what would you say would be a more realistic boil volume?

Just plugged your recipe into brewmate which I use for recipe calcs and it came up with a volume of about 35l befroe the boil based on a 90 min boil with 12% evaporation and 3l lost to hops, trub and deadspace in my boiler (YMMV)

How much would that change for a 60 minute boil?

Looks good except that I'd go with a light crystal like a caramalt. Try something 10-15L but definitely lower than 20L so that the caramelly taste stays out of the hops way. Bump up the sulphates

Volume changes to 33l before a 60min boil.
