Mashing in food-grade plastic fermentation bucket
So I have been dabbling with the use of my sous vide immersion heater for maintaining a perfect mash temperature (it's pretty unbelievable how efficient and accurate these guys are). I have only been doing smaller batches (~3 gallons) up until now. As I have looked to go bigger I have tried to find polycarbonate food bath containers that are large enough, but without much luck. Then it hit me...my MoreBeer Buckets are food grade up to 180 degrees!
So, my plan is to mash in there and then move to two 6 gallon kettles for a split boil (working with an electric glass stove top that won't allow me to achieve a boil on a full 5+ gallons of wort).
Question is, do you think the spigots are also food grade? If not, I can always just use my bucket that does not have a hole/spigot, but it would be much easier to transfer the mashed liquid into the two kettles with the spigot vs. pouring straight from the bucket or siphoning.
Thoughts?
Thanks!
