We are constantly assaulted with change; sometimes it is instantaneous, and other times it is indeed a work in progress. Not all of this change is imposed on us by legislation or cultural pressures. One aspect of change pushes us toward "trends," which are less apparent but nevertheless change. Many factors contribute to change, and indeed the wine as well as beer industries are no exception. The beers which are popular now will undoubtedly change as people's perceptions and tastes evolve. Every alteration contributes to a specific or, in some cases, a broad trend. Craft beer brewers might be the second oldest profession behind prostitution, according to reports.
