Brewday 31/01/2017 - Scottish 100 Shilling Ale

William Younger 1879 100/- Scottish Ale

This is a historic recipe provided by top beer writer Ron Pattinson whose blog Shut Up About Barclay Perkins is a great source of old ale recipes. I'm brewing this 100/- ale as part of a homebrew event where members of Manchester homebrew club and my group Chorlton home brewers are brewing several of these 19th century Scottish ales to bring to a tasting with Ron at Beer Nouveau in Manchester on April 2nd. I'm not sure how we'll know if they taste authentic but hopefully they will all be great beers.

Recipe

This is a very simple recipe!

Pale Malt (I used Golden Promise for extra Scottish authenticity) 5kg

Cluster 90mins - 58g

Goldings 30mins - 58g

Yeast - WLP028 Edinburgh Ale Yeast

OG should be 1.070 and I'm aiming for 17lt into the fermenter.

Results

Not brilliant, I got 16lt in the fermenter but an OG of only 1.060. That's only 62% efficiency, I usually get about 75%. Hopefully the yeast will achieve 70-75% attenuation resulting in an ABV of 5.8% which is close to the original recipe specification. The difference between my recipe and the brewing record is the level of apparent attenuation, the historic recipe has apparent attenuation at 63% which is low for this yeast strain.
