First time doing chromatography for Malolactic on reds - it’s been going for a few weeks (since 10/16) - I have the ever so slightest hint of a showing for malic acid on my cab franc - obviously still more to go on the cab sauv - not sure if people can tell from the photo but I’m trying to decide if what I’m seeing in the cab franc is just a ghost of the lactic acid being pulled upward and if I should add sulfites. I’m leaning towards yes.
