Ask Wine Wizard
Jeff Griffin — Felton, California asks,
For the last two vintages, my Chardonnay, fully dry and through partial MLF (stopped with SO2) went into the bottles after a few months of settling and a couple of rackings. I Add inert gas while aging as well as keeping it topped up in the carboys and now my new variable volume tank. At bottling it always smells fine, but in about 3 months, it develops swampy, reductive odors. A day sitting in open air resolves the smell, but it’s awkward to give a bottle away and have to tell the recipient why it smells bad and how to fix it. Any advice on how to prevent this next year?
