Orchard Heater

Rows of galvanized metal heaters are a familiar element in winegrowing regions, including some of Napa’s traditional vineyards. This orchard heater, also called a smudge pot, was one of many that stood near the ends of vineyard rows at Stag’s Leap Wine Cellars in the Napa Valley. The heaters are used to protect the grapes from freezing when the temperature drops overnight during growing season. Fueled with kerosene, they are often used in conjunction with large fans set in the middle of the vineyard, which help distribute the heat.
