a question that i think fits into this thread- i make a lot of ginger beer with a ginger beer plant, 1.5L batches that contain the fresh juice of 1 lemon, and the gbp tucks right in and has no problem fermenting, but i just tried to ferment the same recipe with some leftover ale yeast (s04), to ferment dry to 6% and then backsweeten to the same sweetness as my ~1% gbp batches. fermentation has not really kicked off after >24h, although i haven't re-checked the gravity (started 1.045), there is not much action in there. could this be due to the acidity of the lemon? could check the pH but i haven't. i just threw in the dry yeast, no starter.
