Review on Homebrew American Amber Beer Ingredient Kit by Anthony Juat

When I first started homebrewing, my first handful of batches were brewed using these Brewer's Best extract kits. I have never had a problem with any of these kits until now. The dry yeast bag I received was from a different brand and not vacuum sealed, which was not typical of other Brewer's Best kits I've seen before. Followed the directions as I always do with kits, they don't change much from recipe to recipe. A week later my gravity readings hadn't changed and I was now left with a useless batch of 5 gallons of wort. I'm not sure if the yeast I received was expired, mispackaged, or mishandled by the seller, but I've lost confidence in buying these kits online. Next time I go to a home brew store to make sure the yeast pack hasn't been swapped out for a lower brand/quality I can't trust the online sale of these kits.
