Pelforth Brune is a great beer...I've been after a recipe for a long time.
This is what I've found out about Pelforth.
Pelforth is a Bock, which is closer to lager than ale.
Pelforth, was first brewed in 1935 using two different types of malt and English yeast
Alcohol Content 6.5 %
Bitterness 21. EBU
Colour 70.0 EBC
It takes 43kg per hectoliter, that's a lot of malt
An hectoliter = 100ltr so that into gallons is 21.99 gallon, but 43kg div 4 = 10.75kg per 25ltr brew (5gal)
Which comes out @ 1.100 which sounds high!!But you need to scale it down from those figures as their mash eff's are different to ours.
23.5 ltr and 75% efficiency = 6.5kg of grains giving 6.2% abv
I do now have a recipe from a fellow brewer, it's AG if your interested?? I've not made it yet as I only got hold of the malt last week and have not had the time to try it. The guy is sending me a bottle soon to try, but he did say that it's very close to the beer.
