no it does not fit bottles only cans sadly, bit of a faff i washed out a can and transferred to that as said allowed the sediment to remain in the bottle.
Came out smoother and the head on stout at lest was creamer and lasted longer.
In essence did what is says on the box tastes more like draught than a can or bottle does, would I use it with say a can of Guiness draft probably not, but my stout was slightly over carbonated could feel the bubble on the tongue when first poured from bottle via this was gone and tasted much better
