Syrah Malo and Oak into the Barrels

syrah in towels It’s been about 4 weeks since I added fresh malolactic bacteria to the syrah to try to get MLF going again.  I’ve been stirring it once or twice a week and keeping a heat pad on it overnight and in the cool parts of the daytime to keep the temperature between 70 – 80∘F.  I tested the malic acid levels today, and levels have not changed at all!  I’ll check again in 2-4 more weeks, but it looks like I’m going to have to treat this wine with lysozyme and give up on MLF.

I also stopped by the office winery today to check up on the barrels.  Dave added some sulfite last week, so I wanted to check the free SO2 levels.  He also commented that there isn’t much oak in the wines this year, so I wanted to check that out for myself and see if we needed to add some oak cubes to our barrels.  Indeed, both the merlot and petite sirah are loaded with big fruit-forward flavors this year, but there is really no oak detectable at all.  I went ahead and dumped in about 15 ounces of a mix of heavy and medium toast American oak cubes into each 30-gallon barrel.  We’ll need to check on these wines again in 8 weeks, that is the minimum time the wine should be exposed to this new oak. merlot PS free so2The free SO2 for both barrels is about 27 ppm, which is right on target — 25 to 35 ppm is a good range for free SO2 at this stage of winemaking.

  1. Gisela,
    It would be a shame if you can’t get mlf to finish on your Syrah. A couple of questions:
    –Did you use any mlb nutrient? If not, check the Morewinemaking.com website for a good protocol.
    –How are you testing the levels? Paper Chromatography? I’ve read that other methods aren’t as reliable.

    You might give a shout out to the folks at Winepress.us about this. I’m sure we can get this through malo for you!

    Cheers,
    Steve

    I think I might throw this one out to winepress.us, as I’m exhausting all of my other options. I did follow Morewine’s protocols for MLB inoculation, and got my supplies from them. I used the Acti-ML and “Bacchus” dry MLB; I think at the time I needed to order it most of the other options were not available. This syrah does have pretty high alcohol, the “wine committee” decided to leave the must at 26.5 brix when the yeast was inoculated.

    I’m using the Accuvin quick tests to test for the malic acid levels, and my experience with this test at least is that the results are very obvious and accurate. I have no doubt that the malic acid levels are not dropping at all!
