Recipe made for Arsegan 50L all-in-one kettle (Hopcat, Robobrew, BrewDevil, etc..)
Mash in at 45 for 15 minutes.
Mash at 55C for 15 minutes.
Mash at 67C for 90 minutes.
Mash out at 75 for 10 minutes.
My experience (>50 brews) with the kettle suggests that starting at 45C provides for better flow and efficiency through the mashing process.
Fill kettle to 41 litres.
Remove 6 litres for sparge. (warm slowly on stove)
At mash in temp (45) add milled grains slowly.
Mash per above.
Two hops drops. At -60 minutes then at -15 minutes. 2nd hops is more "flavour" than aroma.
Steep final hops 15 minutes then remove and cool.
Aerate and yeast.
Initially used S-04 English Ale yeast with a big starter. Now using reclaimed S-04 from previous batches. Used 5x already from one yeast starter.
Doing initial fermention at 15C. (Have used 15-17C) Raising to 20C after a few days.
This is the 5th brewing of this recipe with tweaks. Each brew used a significantly different malt bill. I'm trying to find a stable recipe with far less colour but still very red. This time using recommendations from Weyermann.
Also my first brew with 100% RO water. Building the water back with gypsum, epsom and calcium chorlide. First guess based on Palmer/Raminski. 75 ppm Ca, 100 ppm Cl, 100 ppm SO4
