Ted Hammer, his brother Alex, and a childhood friend, Chris Sorensen, started Hammers Family Birch. They now have 6,000 trees on 100 acres of land. Each tree produces ten to twenty gallons of sap per season, and it takes 135 gallons of sap to make one gallon of birch syrup. They also harvest chaga from the trees and produce several natural remedies from sap, bark, and leaves. For more information about the products and which retail stores carry them, visit hfbirch.com.
