I never have and never had an issue…but many of the packages say to put in fridge after opening.
It’s not a bad idea for flours in general as the oils will go rancid after a while at room temp, and rancid oils not only give an off flavor but are quite unhealthy to consume.
Any flours that touch raw meat gets bagged and frozen/ labelled dated. For later reuse. Otherwise no.
Came back months later and reliked my own comment. Lol I was like this person is exactly like my process. 😅😂
The only flour we refrigerate is the America’s Test Kitchen blend. Other flours I like to keep inside of tupperware but we do store in our cabinet pantry. I’m sure it’s great to refrigerate if you have the space.
I freeze high-oil-content flours like almond and flax, and the ones I use less often. Those that I go through fast stay in the pantry.
