On the contrary. Had a Taiwanese roomie. He’d buy the 50# or whatever bags, and just about had rice with every meal.
The cooked rice would occasionally begin to grow something if he got distracted from his routine.
Don’t remember it otherwise being a problem with storage, dispensing, or insects.
He LOVES it.
The largest amount I ever bought was 25 lb and regretted it, had to throw out the last 10 lb in the FL summer. Nowadays, I buy haiga, in a brand that comes in a large bag with three 5lb bags, each sealed in nitrogen. I open up one, pour it into a large cleaned-out 5lb plastic container (that was sold containing birdseed), and find it very convenient, also knowing that the rest of the rice isn't going to go bad waiting for the 2-3 weeks it will take for me to eat the open 5lb bag.
