Even though I subscribe to dozens of wine blog feeds, there are but a handful of sites that provide truly meaningful learning experiences helping to further my wine knowledge.

Thor Iverson of oenoLogic is one of those few wine bloggers whose writings grab my attention, invite me to read, and encourage me to study. His recent posts on alcohol levels in wine are terrific examples of how Thor can take a current blog topic and expound on it in a way that takes you beyond what has already been stated, resulting in a deeper understanding of wine.

Thor is also unique in the approach he takes toward commenting on wine, for it is grounded in a set of core principles. These principles are explained in his statements on the practices, methodology, bias, and ethics associated with his wine commentary. Even on something as simple as writing a tasting note, Thor goes to considerable length explaining what makes not only a good one, but more importantly a useful one.

How many wine writers do you know that go to such an extent to explain the principles guiding their commentary? Find out for yourself by exploring the logos of Thor Iverson.
