The Champion Evaporator was first manufactured in Hudson, Ohio in 1881, and in June of 1890, G.H. Grimm secured a lease for land alongside the railroad in Rutland, Vermont and over that summer erected a 120 by 40-foot one-story building.

There was another, completely unrelated, Champion Evaporator Company that operated in Berkshire, Vermont and later Richford, Vermont about this same time in the 1880s. This company was relatively short lived with evaporators in production from 1882 to about 1887.
