I've been having very significant drops in Ph after my last nutrient addition at 1/3 sugar break. Until then the pH only drops slightly.
I just moved 2 one gallon mead batches to secondary. Both above 3.6 until after that last nutrient addition, then they jumped down to 2.9 and 3.2 in a couple of days. I added 1/2 teaspoon of K-bicarb and one read at 4.2 the next morning (I should have checked both, but assumed they would both be higher).
Tonight the 4.2 mead was back down to 3.7 and the other one was at 3.2.
Any reason these meads would keep moving down?
My best thought is that the 1/2 teaspoon of wine tanin I added to each batch is somehow binding with the carbonates in the water and dropping them out.
