You are overthinking it!
If you see my set up you would laugh
Anyway,
Bottled my tamarind concoction today. Darker than my "standard" cider, but no longer ugly. Just the remaining foam looks dirty.
Started adding my tinned apple juice, till I suddenly decided to check the label.
It got potassium sorbate as preservative unlike the vitamin C of my other batches.
I poured 2 litres, will see tomorrow if it ferments OK.
Added complication: our temperature dropped. Hope kveik still likes it!
Now having the first bottle of the batch that went into cooling yesterday.
It's too early. It always tastes better after 2 days. But I have done it with all batches, and I'll just continu.
One more badhabit won't make a difference
