Hello team, I am on my 3rd gen of rum wash in a 200l olive drum, I used this size as I could get a 44gal drum heat belt to keep it warm during winter. After 3 days at 28° it stoppped bubbling so I figured it was ready. I checked the FG and it was only half way through the fermentation (5%sugar left) ... (I didn't check the SG...) Anyway, I checked the PH and it was like 3.8, so I added some bicarbonate soda to raise it and continue chugging along. 1x500gram bag later it hadn't risen much at all. 2 days later and another kilo it went up to 5.2 oh but no moment on the air lock.
I think back now and maybe the fermation was done and I've just added a heap of bi carb. Any advice? Just run it and see if it tastes good?
