I cracked the grain for my barleywine today, 15kg of Joe White Trad Ale. For revision, this is the recipe I posted a couple months ago:
Blunt Force Trauma
OG 1.100
~100 IBU
~30 EBC
20-23L
Joe White Trad Ale 15kg
Pacific Gem 14.4%, 20g @ 60
Simcoe 13.3%, 20g @ 60
Pride of Ringwood 9%, 20g @ 60
Cluster 7.2%, 15g @ 30
Fuggles 3.8%, 7g @ 30
Goldings, 5.6%, 20g @ 15
Pacific Gem 14.4%, 20g @ 15
Simcoe 12%, 20g @ 15
Amarillo 8.5%, 20g @ 15
Chinook flowers, ~20g @ flameout
Coopers pale ale yeast, slurry.
66°C mash
20°C ferment
I have decided on a few alterations/addendums:
I will mash at 64°C to help the attenuation a little more, and probably stretch it to 90 minutes if I can wait that long.
After much deliberance I [edit]
almost decided to drop the Coopers yeast. Last year I brewed an aussie strong ale (Old Regret) that produced some heavy fusels thanks to a high ferment temp and right now I am drinking a coopers sparkling ale that is producing a ghost of similar flavours which made me worry about high gravity ferments and the yeast's ability to deal with them. However, I have decided to be a true brewing pioneer and see if I can get the yeast to work for me.
I am going to throw maybe 300g of Thomas Fawcett crystal and 200g of chocolate malt into the second runnings and draw it off for a small beer. The beer I make with that will be purely a spur of the moment decision, however I am going to aim for a starting gravity around 1.040. This small beer will provide the yeast starter for the barleywine while the wort sits patiently in a jerry.
I am going to try to keep the barleywine ferment between 15-20°C by the strip thermometer on the fermenter until it reaches approximately 50-70% apparent attenuation (ie from an OG from 1.100 to 1.050-1.030. Then I will allow it to raise to a maximum of 24. I am hoping this will help the yeast finish without allowing any dodgy by-products.
Something I am also considering, but ultimately will probably dismiss, involves saving extra yeast slurry from the small beer. Then, periodically waking sampes up with a fermenting barleywine injection and adding it to the fermenter to give the ferment some fresh yeast. My main concern over this is adding too much yeast, and ultimately I think I will skip the idea, though it is one I will consider in future.
Finally, the hop schedule might change slightly thanks to the consumption of old stock and the gathering of a kilo of new over the last month. It's all good.
