I started a FWK Bordeaux In Jan 2022. I have made dozens of wine kits over the last 5 years and I carefully followed the FWK instructions - I did add 1/8 tsp PotMet after initial fermentation was finished. Initial SG was 1.104 ended at .994. I did not test the PH when I started the kit (do you normally do this for wine kits...?). I have been bulk aging this wine since Feb 2022. I racked it a couple of days ago and tested the PH and SO2 and was surprised to find the PH at 3.67 and SO2 at 8 PPM (according to the SO2 table that I have the SO2 should be about 38 PPM). I then added 10 ml of a 10% sulfite solution and tested it a couple of days later. It is now still a PH of 3.67 and SO2 of 12 PPM (I ran the tests twice to be sure). According to the WineMaker.Mag calculator 10ml of a 10% sulfite solution should have brought it up to 35 PPM SO2. I am not sure what to do next - add tartaric acid - or add more 10% sulfite solution. It tastes okay.... I am afraid if I bottle it now it will spoil... Or blend it (I do have another FWK Bordeaux kit (and 5 other FWK kits) in process as well). Any thoughts? Please help... Thanks!!!!
