No, it has not arrived yet but I'm pursuing the subject of vacuum storage with great fervour, spurred on by je ne sais quoi?
Anyway, I've just found the following review on the Amazon UK website about the Vac-U-Vin kit, and I quote: "I bought this set mainly for helping red wine last longer. Sometimes I'll leave half a bottle for up to a week - with this easy to use pump it doesn't go 'vinegary' and off colour like it used to. I've also found the food savers helpful - the smallest one is good for storing multiple bags of spices, which smell so strong they'd otherwise taint the other items in my cupboard. The larger ones get crammed with half used bags of sugar and ground nuts - the vacuum storage stops my brown sugar going so hard, and the nuts stay fresher longer."
I find that last sentence of great interest, it "stops my brown sugar going so hard, and the nuts stay fresher longer". Indeed! Now, I would like to ask any mad scientists who may read this group to explain to me in non techy terms why brown sugar and nuts do not apparently dry out, yet perceived opinion here thinks bread will?
According to another reviewer this kit is very handy for anglers as it can double as a "branded pellett sicpump", whatever that is.
(Oh, I'm so bored today... )
