Is the garlic grown in California or China?

Bottle information, small print on the back, says Product of China. Kirkland granulated garlic is a product of California, USA, and it says so on the bottle label. I dumped, unopened, my bottle of McCormick granulated garlic after I got it because it was from China, and ordered the Kirkland..

Hello...No, McCormick does not use irradiation on any of its consumer products. ~Tina

The label says: "Packed in the USA" but nothing about country of origin. Their website doesn't even list this product (instead they only list 2.62 & 4.5 oz "onion powder"). I have to say that I do like it, and it has good taste and texture. Congress removed the "constraints" of country of origin labeling due to "good" lobbying efforts. Wikipedia mockingly states that: "The repeal was a part of the omnibus budget bill" so it was hidden in there with all the junk Congress does.

What is the expiration date? How long does it stay fresh and shelf-stable?

No expiration date. Stays years (I'm really not kidding). I always bought my granulated onion and garlic at Costco; however, they don't carry the onion anymore. The last bottle I bought had to be 21 to 3 years old. Hope this helps.
