My homemade wine is fizzy, What happened?
Answers:
Some winemakers actively encourage re-fermentation, namely producers of sparkling wines. If you bottle the wine with a small percentage of residual sugar and bottle the wine with crown caps like a beer bottle, then you capture the carbon dioxide in the bottle itself as opposed to having it dissipate in the carboy. With the right base wine this extra fizz can make a ho-hum wine sizzle. If your wine was dry at the time of your first filtration, then what you are most likely experiencing is carbon dioxide released by malolactic bacteria.
