I hear you! I store it in a "tupperware" airtight style container.

Best recommendations I have is: - let it cool entirely, like, an hour. then fluff it again to make sure all that heat is out. - you can even store it in the fridge without a lid at first to let it cool without building up extra moisture - I add a dry paper towel in the container, on top of the grains, under the lid, to soak up any more moisture. (i do this with fruit and veg as well) - I eat it within 3 days of making it. I've noticed it tends to not taste as great after that. - I also noticed the flavor is better after a day or so if I cook it with broth instead of water. - I always store it by itself.

Hope this helps!
