Hi all, Been a long time since I used the 3 tier AG system... But unfortunately my memory is shot! And learning dificulty set in. After contacting Fil who I bought the system from for all the losses etc. But tbh I struggled til now, piecing the info into what made sence to me.. Thx Fil for your emails & pm's. So looking how I should work out it: AG losses boiler - 1l dead space hops - ~0.5L (for 100gm of hops) Boiler off- ~2L mash tun- 1l (with manifold) grain - grain bill amount 5.19kg (grain -5.19l ) HLT - 3.5L (dead space again) = 12.74l = amount to have at the end..(23l) + losses.thats strike water + sparge water. = 35.74l The boiler was a PITA could put 5l as usual...had to put 20l then the water run out!!! Due to the type of the manifold.. I knew I had 27l post boil before cooling... Cooling was approx 4l lost, ending up with 23l in the FV. Is there anything wrong with my working out? Lol recipe I'll use. Centurion Ghost Ale clone 23l 3kg Marris otter 360g crystal 90l 970g choc malt 850g roasted Barley = 5.19kg grain bill 8g fuggles @ 60 mins 10g challenger @ 60 mins 5g Bramling cross @ 15 mins 8g fuggles @ 15mins 5g Bramling cross @ 5 mins =34.02g hops bill Irish moss @ 15 mins English Ale Blend WPL085 Compton tablet, Gypsum in the HLT. Mash @ 68C Est OG 1.048 Est FG 1.015 Est ABV 4.4% I've spent been days like a jigsaw getting the info how I made my brews all them years ago! And I've thinking I'm confident to use the kit again, for notes and when my pal wanted the system.. It'll be a week or so once I finalise the set up and the recipe. One thing I would have transfer the post boil Into the GF for cooling as my wort chilling is still up Scotland.. Any pointers in this setup and recipe I'll be really apreciate it.
