The most recent grain bag I got (WHS) seems to be a rather fine crush and both the mash and sparge were a bit problematic. Should have used rice hulls, but being wise after the event rather seems to define human existence.
Anyway, today's brew was a Saison, with a very straightforward grain bill:
4.5kg Pale Malt
0.5kg Vienna malt
0.5kg Cane Sugar
The mash was one of those where the the flow through the grain was so slow that the pump picked up more air than wort, so much foam on the top and some angst from the brewer. Did not do the usual stir of the grain at 30 mins, because the grain was too deep in water/wort. So 30 more mins into the mash, up the temps go to 75C for the "mash-out". Temps at the bottom of the GF go up, then down and basically consistent with low amounts of wort below the grain basket.
On to the sparge - which took around 100-110 mins. The flow through the grain pipe was so slow that I resorted to adding around 1/2 litre of water and stirring the grain after each addition, trying not to repeat the "worst ever disaster" which is briefly described on another thread. Eventually, got to a point where I could get on with the boil, so, as the book (well one book anyway) says that Saison shows Citrus notes and I got a1kg bag of Citra pellets for Xmas 2023:
10g Simcoe @ FW
30g Citra @ 5mins
Very tedious brewday, though when I shove the numbers into BrewMate, I get insane efficiencies - 85 or 86%, after months of normal 75-80%, with nice, easy mash / sparge experiences.
Looking forward to doing some different Saisons in the coming weeks - Special B, Carapils, etc additions.
