I am making a RJ Spag EP Sauvignon Blanc. I went thru entire 8 week initial process and cold stabilized for another 2 weeks. I am bulk ageing for 6 months next and ran the Accuvin SO2 test and got what I guess is a 90. It went beyond green cap range and that was my best guess for red cap. I expected to add k meta. I did not taste or smell sulpher. The wine was great. But can the SO2 test number be that high? The only k meta addition was in the kit during clearing/degassing stage. Appreciate any advice.
