This is PeterJ's TrustRating, which is based on both the number of reviews PeterJ has written, and how many other people have voted those reviews as "helpful." It's a way to quickly to determine the value of any single review or reviewer, because it's based on how helpful PeterJ has been to the Kudzu community.
Carol from The Tasting Company organized an excellent event. It was educational, fun, with excellent wine and food. She took the time to find out what I like and incorporated that into her presentation.
