The Harvest: How Climate Change Affects Where Wine Grapes Grow

With climate change constantly in the news, many people often ask about its effects on various wine growing regions around the world. While the extent and cause of the change in the climate is unclear, a shift in average temperatures and seasons has had an impact on areas that have traditionally been regarded as established growing regions. In fact, True Fabrications carries many essential books on the topic.

According to an article in USA Today, average temperatures are expected to be 2 to 4 degrees higher than they were in the 1970s. No matter the cause of such increases, the effects on many wine regions would be drastic. A temperature that is constantly warmer by 2 to 4 degrees would not only impact day to day growth, but also the push harvest to an earlier date. An article from Wired.com featuring the subject says the increase in temperature would “eliminate wine-grape production in many areas of the United States.” In America, areas like California’s famous Napa Valley and centuries-old wine growing regions overseas like those in Southern Europe would be dramatically altered and possibly eliminated.

However, this new change in weather would also open the door for other areas around the world to take up grape growing. Locations that have been too wet and cold in the past may become the new garden states for wine growing. Areas like Southern England, the Willamette Valley, Washington’s Puget Sound and New York’s Finger Lakes area, are a few of the places that have expanded in recent years. While many of these areas have already been established as great grape growing areas, their popularity will only continue to increase should the global climate continue to shift.
