WINE DIAMONDS: A Documentary Film

Forget everything you thought you knew about wine!  Wine Diamonds: Uncorking America’s Heartland explores the difficulties and excitement of creating a new wine region in the Heartland and rewrites winemaking history in the process.

Wine Diamonds: Uncorking America’s Heartland is a fun, informative and intriguing film that begins by tracing the historical significance of one of the early grape breeding pioneers of the Midwest, Elmer Swenson and then explores the challenges of grape production, wine making and consumer acceptance in the upper-Midwest.  Five winemaking families share their person stories of struggle and success as they attempt to create a new wine region. World renowned wine authorities, Doug Frost (Master Sommelier and Master of Wine) and Tim Hanni (Master of Wine) answer the big questions about cold-hardy grapes and wine. The film ends on a high note as key figures in the wine industry imagine the future of this new nontraditional wine region.

Internationally recognized wine authorities and experts nod approvingly at the wines emerging from these new grapes. Exciting new cold-hardy wine grapes such as Marquette, Frontenac, Brianna and La Crescent have captured the attention of wine fans and critics from across the world.

Wine aficionados are often a little slow to recognize and accept new wine regions and grapes; however, the experts agree something great is happening in the Heartland. Traditional method sparkling wines are gaining appreciation and look to be very promising for this new wine region.
