I'm interested in the replies here. We've been open for a year successfully making clear spirits to pay the rent up to now, and finally we're starting our brown spirits. I'm a Rye fan, so that was a logical start for me. This week was our first stab at it. Our mash is essentially 2.5 lb fine rye flour per gallon of water. We start with bioglucanase and fermcap (glad to learn of a cheaper alternative!), add hightempase at around 140f, raise to 170f and hold for 1/2 hour, cool to 140 then add amylo 300, rest for another 1/2 hour, confirm conversion with a few drops of iodine in a small sample, then cool to 85f. This is where we adjust the pH, and I see some are adjusting at other points along the way? Then we transfer to the fermenter and pitch yeast (Safspirit M-1). Our starting gravity was 1.085 which was a little lower than I expected, but workable. However, the distilling run was A) slow as can be - as stated above, seriously barely a trickle for like 6 hours - it felt like our vodka spirit run!!, then B) only gave about 1/2 of the proof gallons we expected. The good news is, what we did get tasted GREAT!! just not nearly as much of it as expected. Here's a part that might explain my low proof gallons - and that's about the method of checking the OG, and FG. It's way too viscous before conversion to get a good OG reading with a hydrometer (it basically just sits on top of it), so we use a refractometer. But at the end, as it ferments and thins out, a hydrometer reading is possible... and zeros out to 1.00 after ~4 days, but the refractometer still reads 1.035? Which one is correct? Did we still have 4.4% potential (unfermented sugars)? Or was something else, "a-rye"?
