AG#72 – Toasted Oatmeal Stout
Posted January 21, 2012on:
Toasted Oatmeal Stout – Its about time I made a Roasted Barley based Stout so the other week I toasted some oats in the oven, checking every 5 mins and turning them, they just began to catch so I stopped at this point (Slight oven-smell to them, hope this doesn’t come through to the finished beer).
Nice solid bittering from Northdown and a little Challenger thrown in at the end too. The Malt bill is just an altered Guinness recipe splitting the 20% Flaked barley between Caramalt & Flaked Oats (should be better than Guinness).
Pale Malt – 70%
Flaked Oats, Toasted – 10%
Roasted Barley – 10%
Caramalt – 10%
Northdown – 6.2 % @ 60 mins – 42g (FWH)
Northdown – 6.2 % @ 30 mins – 42g
Northdown – 6.2 % @ 0 mins – 15g (15min Steep at 100c)
Challenger – 7.6 % @ 0 mins – 15g (15min Steep at 100c)

Copper filling onto First Wort Northdown hops:
I managed the protafloc all by my self:
Flameout hops going in:
Malt Recycling, she turns it into poo amazingly well:
One division in the meniscus, 1046 on the nail at 20°c:
Pretty slow but no fuss brewday, left the copper to clean later, in the fridge set at 19.5°c
According to BeerEngine I just topped 90% Mash efficiency on this brew, I shall put this down to the Oatmeal which simply disintegrated in the mash and the extended mash rest.
