If you haven't noticed before on this site, there is a search function at the upper left. This is for a search of the site. If you want to read what I said about a wine previously, just type in the name of the wine.
I've now added a more comprehensive search in the bar at the bottom. If you want to read what others say about a wine being reviewed or if you'd like more information about a term, an appellation or a producer, Google will do the research for you. Just type in the name or the term, and you'll get search results within a few seconds.
