Australia has been producing wine since the late 18th century, shipping its first exports to England in 1854. Today, the Land Down Under is one of the top producers of wine in the world. So it should come as no surprise that this popular, self-paced (and free) online course is taught by four instructors from the University of Adelaide. Readers who take the class will learn to "evaluate and communicate the various sensory attributes" of wine. They will also come to understand the "structure, growth and development of grapevines" and, by the end of the course, will become skilled in contrasting "the different winemaking techniques employed in the production of different styles of wine." For readers who are looking for an excellent, entertaining, and cost-free introduction to the wide world of wine, this may be just the resource.
