I've stressed about SO2 in the past but from advice I received on this forum- 1/4 tsp of kmeta every 3 months during bulk aging. 1/4 heaping tsp if racking (air exposure). Until I make a spoiled a wine, this will be my go by. AFAIK, following this is being conservative anyway. More is acceptable but less would probably also work. This takes some stress off my shoulders. Making wine should be enjoyable, right?
If heard more experienced winemakers mentioned at one point that wines (albiet maybe not good ones) have been produced for centuries without lab equipment.
