Comments from Northern Winework: "This is one of the best new white wine selections from Peter Hemstad at the university of Minnesota. It has long slightly loose clusters with a small wing and turns a beautiful golden-brown color when fully ripe. The clusters average 120g (range 80-200g) with smallish (1.5g) berries. Ripe fruit of LaCrescent typically produces a wine with a pronounced and delicious apricot-like flavor. It is an excellent blending component to add good aromatics to more neutral white wines. By midseason, the selection can develop high sugar in hot climates such as Minnesota, but acidity also remains rather high and needs to be reduced during winemaking.
The wine can be very good, balanced and with good body. In the vineyard, LaCrescent is moderately susceptible to Powdery Mildew and Downy Mildew, so it needs a careful spray program. MN 1166 has proven to be much hardier than St. Pepin, but has suffered injury in the coldest winters. It has proven to be susceptible to cold damage following early spring warm spells. Developed from a cross of St. Pepin x E.S. 6-8-25. The latter is Riparia 89 x Muscat Hamburg. Perfect flowers.
