Alpine Walnuts sell walnuts, hazelnuts and chestnuts. The walnuts are sold in their shells, shelled, green, as oil and as flour. The hazelnuts are sold in their shells and shelled. The walnuts, hazelnuts and chestnuts are all harvested around April and are then available until sold out; typically, this means that the walnuts and hazelnuts are available for most of the year, whilst the chestnuts are available until early Autumn.
