​​​​​Week 6: From Vine to Wine—How Wine is Made at Purdue

By Natalie van Hoose

It's mid-October, and the grapes harvested from Purdue University's research vineyards have been trucked to Nelson Hall of Food Science where they are stored in a cooler, waiting to be processed.

In the pilot winery, enology specialist Jill Blume and her student assistants roll up the sleeves of their red coats and get down to business—destemming, crushing and pressing the dozens of grape varieties that roll through their doors. The juice is then wheeled down the hall to the enology laboratory to be cooled, fermented and racked.

In the following videos, Blume explains each step in the winemaking process for white and red grapes.

Members of the Purdue Wine Grape Team instruct several courses for students interested in viticulture and enology, including a wine appreciation course and a class on commerical grape and wine production. Aspiring winemakers can get hands-on experience by working in the winery and enology laboratory, as seen in the photo gallery below.
