I know the standard for a 1 gal batch is 1 campden tablet. I was trying to find what people do if they just have a bag of kmeta. I did a search and came up with a few different ways. Just curious for future reference.
I don't do small batches but if I did, I would take a small bottle measure in 5 tsp. of water and mix in 1/4 tsp. meta. Put one tsp. of meta water mix in each gallon of wine. Dale.
