There are many aspects to consider in order to be successful at growing grapes in the maritime climate areas of the Pacific Northwest. Typified by the cool summers, mild winters, and variable precipitation throughout the growing season, these climate conditions resemble those of the classic winegrape regions of Europe such as Champagne and Burgundy in France, the Ahr and Franconia areas of Germany, Vinho Verde in Portugal, and the areas on Lake Geneva and Lake Zurich in Switzerland. This suggests that the maritime PNW has the potential for producing grapes and wine types similar to those areas.
