SO2 Testing Question for Masta and others

[Hal Maulden]

Bill,


In most cases you are correct. In one case, where I am today, SO2 knowledge is very important. MLF. I am working on 4 wines that I will put through MLF (apple, muscadine, blackberry and scuppernong). I need about 20 ppm SO2 to protect during fermentation, but anything over about 25 ppm will inhibit MLF and waste the money for the MLF bacteria.


There is one more option, although expensive, but very similar to titrets pricing. Accuvin makes a test strip, very simple to use, but around $2 per test. Valley Vinters has them.

Aha - the magic work "simple"! In spite of more expense, maybe this is
what is needed for every-so-often testing.

Thanks Hal

Scott et al,


I found a very reasonable source for chemicals and reagents.

Thanks to Hal and Joesph for all the great info and links

For most wines and winemakers testing free SO2 is not critical and will be covered by standard practices but there are times you want to test and it is nice to have a reliable, efficient and cost effective way to do it.
