I had 12 maple trees. It's important to not tap two years in a row for recuperation purposes.

Depending on the tree, a bucket can fill up in less than a day! Trees drip fastest at the beginning of spring.

Complete with filtering station, gas-powered hot plate and the biggest cauldron available. I had to build it far from any house, since the sweet vapour can stick easily.

A paper or coffee filter does the trick. Watch out for bugs!

It took about an hour to being boiling a litre of sap.

And now the long part begins: evaporating 40 parts of water for 1 part of syrup.

To get exactly 104° C, I used a candy thermometer. It's also important to check viscosity with a spoon (not super quantitative but a satisfactory approximation for a physicist).

To delay rotting, I used sealed mason jars. Best enjoyed with pancakes!
