A beautiful spring Saturday here so I started my maple syrup production. I tapped the only sugar maple on my property and it gave good results. Because the sap runs for a few weeks, off and on, I used natural refrigeration to store the drippings. Now that I have as much sap as I will get this spring I used my Coleman 457G Gas Plant to boil the liquid. As the boil continues the solution turns dark as the sugars become concentrated. In order to keep the main pot boiling I preboiled small amounts of sap on my Coleman 500B and then transferred to the main pot. The HGP ran for 9 hrs on approx 2 gal. of white gas. I finished the boil indoors as the weather turned ugly. Final product about 2 liters from 50 liters of sap. This will go good with pancakes or baked beans this summer. This is a welcome task after a long winter.
