I have two handy-dandy buckets I use around the house for measuring out gallon-quantities of liquid (as they're graduated on the side). I'm wondering if there is any way to tell if they're food-grade. They say made from HDPE on the bottom, and I believe that's what standard fermenters are made from...
...I ask because I want to use the bucket to combine my mash and sparge volumes for a stove top all grain. Can these HDPE buckets stand up to 150*F + temperatures?
Back to brewing! It's been too long!!
