I was given a Brewers Best kit for a Nut Brown Ale, it includes the malt extract, hops, grains, yeast, etc... The person that gave it to me was going to get into Homebrewing but never actually did. He said he got it last year for Christmas so it's at least 8 - 9 months old. Nothing has been opened but it wasn't stored in the fridge or anything like that. Is it still good? Should any of the kit components been refrigerated?
