Delicious smooth tasting non-pasteurized Chandler Walnuts. (Photo shows 1/4 lb.) Double A Walnuts is an organic walnut orchard owned by Alan Siegle and his brother. Alan is a close Singing Frogs Farm colleague as a master composter. He and Will Bakx ran Sonoma Compost for years and are trying to build a new composting facility that we fully support Sonoma Renewable. Double A Walnuts are organically grown using sustainable farming practices that build and enrich the soil in Colusa CA.
