    Confusing pH and TA numbers

    I wasn't sure about it as I hadn't added acid before unless it was not within range. Now i know to preference pH over acid and go with that adjustment. Brix was 25. and Yes i log my data every year I've never had it at 8.3 either.

    Confusing pH and TA numbers

    I ended up not doing anything to it. It has a high pH, oh well. It'll have low free SO2. I bottled today. The wine tasted damned good, so maybe it will go fast in two years. Some of the corks I bought (duo Disc) were exceptionally hard to get into the bottle. None of them made it flush. It's all...

    Confusing pH and TA numbers

    i reached out to an old contact who i used to buy grapes from and he said while not legal in commercial winemaking, sulfuric acid could be used. i had not read this, only phosphoric. I'm trying to think of ways to add acid that don't affect taste. Adding tartaric, malic, etc will be perceived

    Confusing pH and TA numbers

    I'd like to not have to guzzle it all down in a few years, so i think i will try lowering it. Not sure how just yet

    Confusing pH and TA numbers

    no other ideas about ph? or should i just let it be?

    Confusing pH and TA numbers

    ok redid it with fresh .2N NaOH and syrah was 5.6, merlot/cab blend was 5.8. Way better than the 6.2/6.9 numbers i got. I also microwaved the sample for a few seconds to heat it up to degas then cool before testing. Got that tip from someone. pH was still 4.3 and 4.05 I oaked yesterday but...

    Residual Sugar Testing

    i was able to get those aimtabs today. Really easy, both were .01-.05%. I didn't have a test tube so i just used a shot glass

    Residual Sugar Testing

    it was suggested to me by a more experienced winemaker to ensure everythings done. I used to just taste and do before and after SG but that's not as precise for % I'm expecting to get aimtabs but the place was closed monday so i have to wait

    Confusing pH and TA numbers

    I do let it sit in the cups for about 20 minutes while i'm gathering supplies. And as for phosphoric I have 25% since I use that for my reagents testing. I'm about to head out to grab those chemicals now and when i get back I'll retest TA first. if it was accurate then...i have to figure...

    Confusing pH and TA numbers

    https://winemakermag.com/technique/1650-monitoring-adjusting-ph he mentions (Pambianchi) phosphoric acid as well as calcium sulfate. I knew the pH was higher than I wanted but i hear mixed feedback on messing with must/wine levels early on. Some add things to make it exact and others don't want...

    Confusing pH and TA numbers

    I'm going to buy a new bottle of .2 NaOH tomorrow. Mine's pretty old. Wonder if it's giving me weird TA readings. that doesn't affect the SO2 numbers i'm getting but I need to get more phosphoric acid for that as well speaking of, I found a blurb online about using Phosphoric acid 30% to lower...

    Confusing pH and TA numbers

    it is also the first year i added yeast nutrients with calculations. In the past i've just added yeast and let it me. I've made good wine so I'm wondering if I'm starting to try too hard and overanalyze things. More nutrients added means more spoilage potential. The wines tasted good and fruity...

    Confusing pH and TA numbers

    I'm getting ready to oak my two red wines and testing today threw me for a loop Syrah - pH 4.29 which is too high, TA was 6.2 which is slightly high (before ferm it was 3.87/9.4) Merlot blend - pH 4.06, TA 6.9 (before ferm it was 3.87/5.8) Both underwent MLF and malic acid test today shoes no...

    Residual Sugar Testing

    I've never tested in years prior but I'm trying to be more precise as time goes on. All my materials show people using Clinitest tablets and using a color chart. But Bayer discontinued these and it seems urine analysis home kits are going to dip sticks vs tablets. I can't fine Accuvin Residual...
