We have two fridges...one at 3C for all the usual "cold" stuff, and one at about 10 to 12C for things that are best kept cool...bread, potatoes, veg, fruit, beer and wine (of course). Works fine.
I keep mine in a potate sack hanging out in the shed, they last weeks. I'd never put them min the fridge and this is the first I've ever heard of them being refrigerated
