Maple syrup is made my boiling maple sap, which is about 2% sugar. It takes about 40 gallons of sap to produce one gallon of syrup, which has a sugar concentration of about 67%. Maple sap contains mostly sucrose, but also nitrogen and minerals, carbohydrates and volatile flavor compounds. [x]
Maple sugaring question: “Is there nutritional value to the unrefined maple sap? Can it be consumed without refining? Have you ever tried some?”
Question from luiswalker.
Cyrus Pringle lived from 1838 to 1911 and is most known for his voracious collection of plant specimens in Mexico. He personally discovered over 1,000 new species. He was a native of Vermont, and the Pringle Herbarium at the University of Vermont is named for him. He began as a farmer and owner of a nursery, and he bred new species of potato for sale. After being imprisoned for refusing to fight in the Civil War, based upon his beliefs as a Quaker, he returned to plant breeding. Around the 1870’s he began plant collection in Vermont, and in the following years traded specimens voraciously, so his specimens can be found across the world.
