Added within 10 minutes of the dextrose? I would assume yeast nutrient or some finings of some sort. Interesting that they’re adding extract in what seems to be end of boil. I’m sure they can get extract of any variety they use and I know in really large systems the yield increase in extract vs. pellets can be substantial.
Like I said. I don’t know at which point of the boil this was. And I cannot confirm that these cans were extract it was just what it looked like to me. I don’t want to make any guarantees! The only thing I’m sure of was the 2 bags of dextrose being added. Again, we don’t know which beer was being brewed. Just trying to get any info out there.
