In case you think this was an error of omission, know that some breweries were purposefully left out of the Ontario microbrewery tiers. In most cases the reason was because I just hadn’t tried enough beers to make some sort of judgment on the brewery. A lot of these breweries would have filled out the bottom tiers, but not always. The leftovers are:
Kichesippi/Heritage/Scotch-Irish (waiting to see how this shakes out after Kichesippi bought Heritage)
Feel free to leave your own judgments or let me know of any other breweries that have been forgotten.
