Tried a Rye bitter today, was a bit concerned over stuck mask stories so went a little conservative a modified a std bitter recipe reducing crystal from 350g to 250g and adding 350g of Rye Crystal. Pale reduced slightly from 3375g to 3300 & skipped 25g Black malt altogether. so total grain bill moved from 4100g & OG 1040 OG to 4250g & OG 1042. It did behave differently in the grainfather, normally there is initially an overflow into the er overflow and later settles down but still a good centimetre of wort above the top plate. Today no overflow at all and drained straight through plate no build up of wort over top plate at all. Looking forward to see how it turns out.
