Estate Grapes

[smartslider3 slider=2]


We pride ourselves on making hand-crafted wines from high quality grapes. Growing wine quality grapes in northern cold climates is a challenge. Fortunately there has been significant research and development to hybridize traditional wine grape varieties (vitis vinifera) with robust native American varieties (vitis riparia). The University of Minnesota has been a long-standing leader in this research. More recently, North Dakota State University has initiated a grape breeding program to develop wine grapes suitable for the even harsher climates found in the upper great plains.

At 4e Winery we are growing several white and red varietals that produce structured and delicious wines.



Marquette was released by the University of Minnesota in 2006 and it has been rapidly adopted in vineyards across the upper US and Canada. Its popularity is due to its excellent qualities for wine including structured tannins, deep red color and complex flavors and aromas. It helps that the vines will survive temperatures down to -36°F! Marquette is a hybrid grandson of Pinot Noir. (75 vines planted May 25, 2013)

Petite Pearl

Petite pearl is the newest red wine grape for northern climates. It was developed by Tom Plocher beginning in 1996 and was first released for sale in 2012. It produces small tight clusters of berries with a high skin to juice ratio providing a complex, spicy and jammy wine with rounded tannins. (100 vines planted May 25, 2013)


Frontenac is one of the first red wine grapes produced for cold climates released in 1996. It is extremely cold hardy, vigorous and makes crisp dry red and delicious fruity rosé wines.  (80 vines planted May 24, 2014)



Brianna is a white wine grape produced by pioneering Wisconsin grape breeder Elmer Swenson. It produces large clusters of golden to greenish-golden grapes. It is especially ideal for making refreshing semi-sweet wines displaying fruity aromas of peaches and pineapple. (75 vines planted May 25, 2013)
