How To Treat Chestnuts for Weevils: Small-Scale Hot Water Bath
$15.00
Eight pages on the small-scale hot water bath we use at EBB Farms to treat chestnuts for weevils. This chestnut weevil treatment guide covers the time and temperature that work, our cooler setup, step-by-step instructions, and how to rest, dry, and store nuts so they stay sweet.
A chestnut can look perfect on the outside and still have a weevil larva inside. A hot water bath stops them. It’s quick, it uses no chemicals, and done right it doesn’t hurt the flavor.
This chestnut weevil treatment guide comes from EBB Farms in Falls of Rough, Kentucky, the farm lab for United Chestnuts. This small-scale setup has worked well for us. We’re getting ready to move up to a larger system as our harvest grows, but we wanted to share what’s worked at this scale for growers who are just getting started.

Numbers From the Processing Floor
The time and temperature in this guide follow Dr. Greg Miller of Route 9 Cooperative, one of the largest chestnut processors in the country. He has run hundreds of tons of chestnuts through hot water treatment, and his experience is the backbone of our recommendations.
