Wow, had no idea. I always assumed that isomerization was more of a c\reaction of the malt and the alpha acids requiring heat to make happen (endothermic reaction). So we're just using heat to extract or convert the acids from the hops and this can be done in isolation? They why doesn't someone sell hop extract that you ca just add to malt?
BTW, in response to one of the questions, the plan is to use all unhopped malt and not use a canned kit.
