  • Hi everyone! This is Brilliant Botany Episode 3, and I'm here today to talk to you about

  • maple trees and maple sugaring. I actually wrote my undergraduate thesis on maple sugaring,

  • so I can probably answer pretty much any question you can come up with about maple sugaring.

  • And if you've been following me on tumblr for the last couple months, you might remember

  • I did maple question and answer series, and you can click on this annotation or I will

  • put the link in the description if you want to take a look at that.

  • Now, I could go into detail about the physiology and science of maple trees and maple sugaring

  • but that would take me quite a long time. Basically, high pressure in the tree's vascular

  • tissue-the network of tubes that moves water through the plant-causes sap to be pushed

  • out when you drill a hole in the tree's bark. In sugaring, sap is typically taken from sugar

  • maples or red maples, though it can be taken from other species, it just doesn't have quite

  • as high a sugar content.

  • This sap is collected and then boiled to remove water. Sap starts out about 2-4% sugar, but

  • finished maple syrup contains 67% sugar. This means a lot of water has to be removed. It

  • takes 40 gallons of maple sap to produce one gallon of maple syrup. All maple syrup is

  • produced in the North Eastern United States and Canada. The province of Quebec is responsible

  • for about 80% of the world's maple syrup production every year. In 2011, a total of 13,075,000

  • gallons of maple syrup was produced in the US and Canada, worth a staggering $470,568,000.

  • But why is maple syrup so valuable? Well firstly, it takes a lot of work to produce. A lot of

  • energy has to go into boiling all of that sap to get all of that water out to make syrup.

  • But also when colonists came to the United States, maple sugar was the only available

  • sweetener, short of importing cane sugar, which was very expensive. So they learned

  • the art of maple sugaring from the natives, and most families had a sugarbush on their

  • property to produce their own maple syrup and maple sugar.

  • Over the next few centuries, sugaring became a lucrative industry that we have today. So

  • those are the very bare basics of maple sugaring. If you enjoyed this video, press the thumbs
