    I opened a bottle of my 2017 merlot. It was good when I bottled it, degassed with all in one wine pump, added k metta. I have a had a few bottles and all was good. The last 2 bottles I opened were gas city. If I place my hand over the bottle and give a shake it blows of pretty good. Any idea on what might be happening here?

    Is it refermenting? That can be one cause of excess gas, if it was all gone at bottling.

    This was one of the only times I didn’t put potassium sorbate in but it was measuring .990. I just checked 2 other batches I did the same exact way and one tasted perfect and the other like the merlot.

    If you didn't add additional sugar, not adding sorbate shouldn't cause it to get gassy. I never add sorbate to wines that ferment dry, that I don't add sugar to.

    When you shook your wine and degassed, how did it taste?

    When I tasted after I shook it and aerated, it tasted a little funky...

    If you degas and let it settle, it should taste better. It may be something other than co2...

    Do you recycle your bottles? Did you sanitize? Maybe it's just those two bottles.

    MLF in bottle can cause the gas, and the funky taste or smell.

    “When in-bottle MLF occurs, carbon dioxide becomes trapped in the wine, resulting in an unpleasant fizziness. A consumer opening a wine that has accidentally undergone in-bottle MLF may think the wine is continuing to ferment as the bottle releases carbon dioxide. At the same time, uncontrolled, in-bottle MLF may impart off flavors and aromas to wines, such as cured meats or fetid milk.”
