Just to clarify Maris Otter is a 2 Row grain, Crisp call their Amber malt Biscuit as well so I used Biscuit. I use a yeast at 82% attenuation so I have to keep the OG low to achieve 6%ish beer.
Today I brewed 20 litres of Dogfish Head 60 minutes IPA
4500g Maris Otter
400g Biscuit Malt
20g Simcoe @60
20g Amarillo @ 15
30g each of Simcoe and Amarillo for 20m whirlpool at 80C
CML Five yeast
OG 1056 BHE 73%
