Most wine writing assumes you already know the mechanics. This collection covers them directly: how to taste in a way that actually builds a memory, what temperature does to a wine, when decanting helps and when it strips a bottle, how long an opened bottle really lasts.
None of it requires equipment worth defending. A decent glass, somewhere dark and cool, and a thermometer will cover almost everything a home cellar needs.
The club wrote about several of these subjects during its run — glass shape and the taste of wine among them — and the rest of that writing sits in Hot Wine Topics.
