For the second night in a row, Eric Blumenberg, 35, stayed up overnight to tend smoky fires at the main vineyard for Blumenhof Winery in Treloar, Mo. on Thursday, April 22, 2021. Blumenberg was attempting to create an inversion layer of smoke to trap heat over the grapevines to protect the delicate buds from frost damage as temperatures again dipped well below freezing overnight. 

Blumenberg's dad Mark Blumenberg, 69, showed up at about 3:30 a.m. to help his son tend the fires at the family's vineyard. Mark Blumenberg planted the first grapevines in 1979 on the family's vineyard. It is the second year in a row frost has damaged the crop.

Blumenhof Winery, located in Dutzow, is a small, family-owned business, with three generations of Blumenbergs involved making wine. All their wines are made from Missouri-grown grapes most from their vineyard in Treloar and other local growers. "Wine is of a place" said Eric Blumenberg about why they choose to use only Missouri grapes.
