When I rate items on TasteOfZach, I use the whole rating scale from 1-10. A 5 rating is a beer I would order at a bar if they didn't have anything else I liked. A rating of 4 and below I wouldn't pay for unless I had to buy a domestic beer for a tailgate party or something similar. I follow these rules for everything I review on TasteOfZach.
