Hello all. Yes I'm new here and to winemaking. I was told by my local store and was given a book but it seems everyone has their own ways and disaster occures unless you take only one path. My problem; I clean my carboy with pot-mete-sulphate. I'm told don't rinse afterward. Then add 1/2 tsp to 5 gal. Well after 2 racks my wine is way too salty. Now what do I do? I heard test kits are not recommended or accurate. Can anyone advise me if & how to test to correct. Thank you.
