How to store garlic?
I always store mine in the pantry. I use it frequently enough that sprouting is rarely an issue. If you need it to last longer you can freeze garlic, though I have never needed to.

Shelf Life

An unbroken bulb of garlic can last 3-5 months in a cool (55-60 F) dark place. Once broken, the remaining cloves last only about 7-10 days. 

Frozen, you can store garlic 10-12 months.
