Several centuries-old apple varieties are attracting renewed attention for their distinct taste and appearance. Esopus Spitzenburg, Cornish Gilliflower, and Hubbardston Nonesuch are among the types being highlighted for their flavor and texture, according to a recent report. The names, described as reminiscent of Dickensian characters, point to the apples’ long histories. Growers and sellers are featuring these lesser-known varieties this autumn as orchard harvests reach their peak.
