Now, I don’t often find myself putting away an open bottle of beer, but I am still surprised that I have never seen a product like this before.  Beersavers are bottlecap-shaped silicone covers for your beet bottles.  They are discribed as a way to keep your beer “fresh and safe,” not sure what they mean by safe, I suppose from falling beer-seeking debris or something.  I guess i could see myself using these when I am serving from a bomber or wine bottle, though.  There are a number of other tips on the website, but I am not so sure i would ever use these to “help keep your beer safely identified when in clubs, bars and restaurants.”
