AG#49 – Sickboy Scottish Ale


This is essentially a re-brew of my Krooks Pale Ale, the first partial mash recipe I did. This time I’m doing a full all-grain brew and using a different yeast strain to get a beer that more resembles a clean tasting Scottish ale. I don’t think I’ve ever done a beer before that had only one single hop addition, so this is new territory for me. I’m looking for a nice, Winter eas drinker, a malty beer that will go well with food. I remember my Krooks ale was particularly good with a sharp, salty cheese.

22/11/2015 – Mash and boil in one day, which should be the new norm for me, to see if it doesn’t sort the clarity problems I’ve been having lately. Brew day went perfectly, wort possibly a little darker than I had anticipated, but still within the style parameters. I’ve got the fermenter in a pretty cool position, but the weather is so cold at the moment, I hope it doesn’t stall.

10/12/2016 – Bottled with 104g of corn sugar (18 litres at 2.3 vol). 8 x 750ml bottles and 24 x 500ml bottles. Taste is extremely promising, toasty and malty.

12/01/2016 – Should be tasting great at this stage, but it’s not. It’s got a fair bit of astringency which detracts from what otherwise seems like a nice toasty, malty beer. Very disappointed with it. I think my sparge temperature must be to blame.
