- It's owned by Smucker's. I normally dislike anything from Smucker's, but Adams is a nice exception.
- If you get the giant jar from Costco, the oil separation is a significant issue. There's a simple solution: dump it all into a big mixing bowl (with the help of a silicone spatula), mix it, and pour it back into the jar. I did it last time I bought it and it was worth the 10 minutes I spent.
- Once it's mixed well, if you give it a quick stir every time you use it, the oil doesn't separate again.
