The glasses, actually recyclable plastic, come pre-filled with 187ml (6.3-ounces) of Shiraz, Chardonnay or rose and have a peel-off foil lid. They cost £2.25 each ($3.37), which makes them more expensive than buying the same wine by the bottle (four glasses add up to £9, whereas the bottle is £4.50).

[Edit] : Reader Meghan H writes: I recently had a single serve wine in Washington at the Gorge Amphitheatre and it was really good!  I had to look it up, and I found your website on my way there.  It’s called Copa Di Vino www.copadivino.com  This product is really, really cool.  The glass is a little different, but is a lot more stable than the UK version looks- you could set it on a table and not worry at all!  I think they’re from Oregon, you should check it out.  (also recyclable)
