I'm following this stout recipe for the second time (it's a good one). I had planned to double the recipe to make ~ 40ltrs instead of 20ltrs.
The recipe calls for:
(2.7KG) 6 lb. Dark Liquid Malt Extract
My supplies just arrived and my homebrew store substituted 3 x 1.5 Kg Cans of Dark LME with Amber LME.
Does anybody know what the effect might be on my stout if I use the amber instead of dark? Would it turn out mostly the same except for colour? Just trying to figure out if I should kick up a fuss with my supplier.
