That’s what I’ve noticed. And I have to read individually labeled onions to see if they are “sweet” or “yellow”. The loose ones seem to often be “sweet”.
I’ve also noticed the big, loose onions appear dark or dusky for about 1/4 of the surface near the stem end. I sniff, through a mask, in the store looking for “rot”, but it turns out they are not rotting, nor moody.
