In general, I'll only do full reviews of beers as I drink them. I enjoy pairing beer with food, or trying to anyway, and will report the success of any attempted pairings in the review as well. The pairings are always performed after tasting the beer on its own and will never impact any of the scoring.
The "Overall" score of a beer will primarily come from my perception of its flavor and mouthfeel, and exclude appearance and aroma from the equation. Essentially, how do I feel about trying it again, and how likely I am to recommend it to others:
1 - Never care to have again / No reason to recommend
2 - I'd be nervous or unenthusiastic to try again / Unlikely to recommend
3 - Sure why not / Recommend under the right circumstances
4 - Happy to try again / Especially noteworthy
5 - Truly exceptional, excited to try again / Top-billing
