I was discussing my plans for this brew recently - thanks for the suggestions. Full details on Brewers Friend here I got a starter on a couple of days ago using yeast/trub of Wyeast 1275 from my AG#4. The plan was very much about using up odds and sods hence odd amounts in the grain bill: 1394g mild malt 100g brown malt 53g dark crystal 293g Caramalt 83g Munich 42g Pilsner 200g flaked barley 2.16kg in total Mashed 6L Tesco Ashbeck @ 67degC for 80mins Dunk sparge 8L @ 80degC for 15mins Added 2L boiling water to the brew kettle 16L Tesco Ashbeck in total 9g simcoe @ 13.1%AAU for 60mins 10g EKG @ 6.8%AAU for 10mins Half a protofloc tablet for 10 mins 5g First Gold @ 9.16%AAU for 5mins BG 1.038 OG 1.046 Seems whatever I do I cannot get Brewers Friend to match my BG, but my efficiency seems pretty consistent from brew to brew that the OG is pretty much bang on. Wort was quite dark, maybe similar to N.Brown, but smelt and tasted very rich and malty. Excited now to see how this turns out.
