One of the four super-hardy pioneer Russian varieties imported to the U.S. by the Massachusetts Horticultural Society in 1835 along with Duchess, Alexander and Red Astrachan. Used as a parent in breeding projects for new cold-hardy varieties, such as its offspring Mantet. Medium-sized round-oblate fruit with smooth waxy pale yellow skin, prominent red stripes and abundant dots. Often covered with a whitish bloom. Tender white flesh is coarse and juicy. Mostly used for summer cooking. Tetofsky is very acidic until fully ripe in late July or early August in central Maine, around the same time as another popular Russian summer apple, Yellow Transparent. Early bloomer. Z3, possibly Z2. Maine Grown. (Standard: 3–6' bare-root trees)
