Recently switched over from bi carb to calcium carbonate - chalk for adjusting or raising pH. ... residual salts/beer brewing reasons mainly.
Found that extended ferment time for the same Rye/corn washes no other change. These two washes are 3 weeks old, sitting at 26c on EC1118 and still powering along like it would on day two. It's normally done in two weeks.
Current Gravity is approaching 1.000 with no signs of slowing down. I expect it to take an estimated 2 more days... at least :think:
Could be a minor yield gain, expecting a couple of low FG's 990's here. Certainly chalk is better for repetitive gens not creating a sodium build up as bi carb does. EC1118 clearly getting on with chalk.
In a nut shell, longer strong ferments, with an expected yield gain
