Hi Brewers
Can anyone help me out with a head-scratcher? I recently brewed a contract Red IPA for another brewery, 1400L batch with 280KG base malt and 86KG of various crystal malts. Water additions were our normal for a pale ale. pH was about right, Conversion was normal or maybe a bit above average. Mash temp was 67'C. We used 600g Safale US-05. It has stopped dead at 1.027. We extracted a sample and over-pitched with US-05 and it went nowhere.
I personally think that there's too much crystal in this recipe but nowhere near enough to explain this under-attenuation.
Does anyone have any ideas?
Cheers and Beers
Karl.
