Your Plum can accept the vast majority of 750ml wine bottles. Plum will work with bottles from 11”-13” in length, and from 2-3.5” in diameter. Some wines (i.e. certain German Spätlese) will be too long to fit and are not for use in your Plum.
Almost all closures will work with Plum including natural cork (up to 55mm in length), artificial cork, engineered cork, and even metal screw caps. Plum will not work with other types of closures including glass stoppers. Please do not put these closures in Plum as it may damage your appliance.
If you have a closure with wax over it, remove the wax before inserting into Plum.
