As a matter of fact, I have one.
I usually get 3 heads of garlic for $1 at Downtown LA's farmers market. Sitting in my little garlic cellar, those puppies seem to last just about forever. Never once sprouts green on me.
Now, over at F&E, heads of garlic came in a mesh pack of 3. The brand is Spice World. A week into the cellar, I popped one open to find the cloves started to sprout. Huh. The other heads soon followed.
The second attempt I didn't even pick any up. There were 2 bags of garlic left and both of them were already sprouting. The third try pretty much yielded the short life span just like the first one.
Where every F&E is getting their garlic from, they've got to fire their purveyor. Unless they're doing this on purpose to push folks to buy the pre-peeled or ready-prepped garlic in the refrigerated section.
Amended Verdict 9/8/08: Earthbound.
Note: After the original posting, I actually bought another mesh pack of garlic because I didn't want to hop to another store. That batch, and the batch after that, turns out to keep quite well. No sprouting after the first incident. Good for F&E!
