The first statement I've quotes is a potential issue - Oxisan, which is considered a one-step cleaner/sanitizer, is better for cleaning than it is sanitizing (being primarily H2O2 makes it similar to PWB) . I would strongly reccomend you switch to either Star-san or iodafor - opinions vary, but I believe the general consensus on one-step cleaner/sanitizers is that they are typically good at one task, the other, or mediocre at both. Anyway, it's definitely something you could try.GasMD30 wrote:All of my materials end up in a Oxi-San (H2O2) soak in the brew kettle while I mash my grains on the stove. All of my water is pre-boiled to try to remove chlorine.
I usually slightly overpitch my yeast, as I use dry yeast. Probably 3-4 g of yeast for the gallon of wort.
I have questions about the second statement. Do you rehydrate your yeast in water before pitching? If so, do you first boil the water and let it cool? Do you keep it carefully sealed while cooling? Over pitching can lead to some issues as well, though likely not the flavours your describing (https://www.wyeastlab.com/com-pitch-rates.cfm see the bottom of the page), but 4g in a 1.050 batch is close to double what you need (unless you're direct pitching, in which case that's probably about the right amount).
