Don't fight sulfites.

You say that you previously showed the "Aeration Oxidation" method. Which episode was that in?

Thanks for this great video. I'm so done using a color based test kit. It's almost impossible to match the color exactly. I'm going to order this test kit tonight. Thanks again Rick for sharing your expertise.

You are much appreciated. I have learned a great deal by watching your video’s. You mentioned a chart that shows PH to free SO2… do you have a link to that? Also, I have started malolactic conversion on a few varsity’s of wines this year and am wondering if you have a chart that recommends PH and free SO2 levels for pre-MF ? I have heard you speak of MF often in your videos but wonder if you have made one walking through all the steps ? Thank you again.

Very nice, thanks! Just wanted to add that it's a good idea to keep a box of sodium bicarbonate (baking soda) handy to neutralize any spills of the Acid Solution or of a wine sample with the Acid Solution added to it; also to neutralize the spent reaction for safe disposal. – Rich from Vinmetrica

Can you discuss why you choose the unit you did vs the cheaper unit or others that may be on the marketplace?
