You don't need vinegar (although some recipes call for it). A dry white wine will provide all the acidity you need. You control the acidity by the amount of reduction of the wine. To get very controlled acidity, reduce almost to dry and then add a spoon-full of water so that your butter can emulsify. My classic proportions are (metric but can be transposed ...

If it were originally vacuum-packed but then gas developed from putrefaction then that would be a bigger concern... but there would be absolutely no question whether that was the case once you smelled it.

I know everyone wants to quote FDA regulations or whatever here, but they are a one-...
