Plum works with any standard 750ml bottle of wine with any standard closure – including natural cork, engineered cork, artificial cork, and even metal screw caps. Plum does not work with glass closures.
If your bottle has a wax seal, the wax must be removed prior to placing the bottle in Plum to avoid clogging the needle.
Plum supports bottles up to 3.5″ in diameter, and between 11-13″ in length. That means it works with more than 98% of commercially available wine.
