A tip to forestall the fuzzy berry issue: after buying and before storing berries, rinse them in cold water and then give them a short vinegar bath. Use 1 part cider vinegar to 10 parts cold water, dump the berries in and let them play for a minute or two before pulling them out. Drain in a colander for a few minutes and then store in the fridge. This should prolong their life quite significantly. It's a tiny bit of a pain but nothing compared to finding an expensive bunch of berries wearing fuzzy green coats just when you were all ready for one. Works for all kinds of berries.
