There are some old folks in my neighborhood, who have restored a fascinating old 18th century farmhouse.
The farmhouse has its own malt loft, that has also been brought back to a working condition.
I help them by converting their pilsner malt into beer for a yearly event at the farmhouse.
The yield of their malt have been somewhat unstable, but over the years I've been able to adjust the potential of their pilsner malt to 1023 (compared to 1036 for commercial 2 row pilsner malt),
which when added with smaller amounts af commercial malt gives a fairly predictable result.
This year I thought I would be more scientific about the process so I made a sample mash in an ordinary pot on my kitchen stove.
I added 400 grams (0.882 lb) of grain to 1 liter of water and mashed for a little over an hour at 65?C (149?F) and heated up to 78?C (172?F) for the last 10 minutes.
I sifted 700 grams litres of 15.2 Brix (SG 1060) from the mash and added another half litre of water, which was succesively sifted out as 530 grams of 5.1 Brix (SG 1020)
When mixed, I now had 1230 grams of 10.8 Brix (SG 1042)
I guess the 1230 grams converts into (1230/1042*1000=) 1.180 lires or 0.3118 us gal.
How do I convert this to a potential to enter in BS to properly calculate my recipes?
