When you are making a very small batch of something, a drop or two of some or other ingredient makes a rather large difference. If you are making 3000 gallons of something, a drop or two makes no difference at all. Which is to say, my guess is that the contents of your extract can are damn near identical each and every time, store to store, year to year. These guys have fine controls, and their company depends on making identical product over and over, and it should be basically pretty easily within their means to do so, with gravity, ph, hardness, bitterness all completely adjustable to them.
