AY Honors/Maple Sugar - Advanced/Answer Key

2. Make at least five taps and boil down at least two quarts of syrup.

• 

  Boring the tap hole with a brace and bit.

• 

  A homemade, traditional tap.

• 

  A tap designed to hold a bucket

• 

  A tap designed to attach to tubing

• 

  Inserting a plastic tap.

• 

  Bucket hanging on a tap.

• 

  Taps connected with tubing.

• 

  An evaporator for boiling the sap down into syrup.

The first step will be finding a suitable maple tree. The tree should be at least 10 inches in diameter. For every extra foot of diameter, you can drill another tap. A brace and bit is the traditional tool for tapping the tree, but you could also use a cordless drill, or if you can reach the tree with an extension cord, a power drill. Whichever tool you choose for boring the tap hole, be sure to use either a 7/16" or a 1/2" bit. The hole should be about 2.5" deep, and angled such that the sap can run downhill out of the tap.

Once the hole has been bored, lightly tap the tap into place (perhaps that's why it's called a tap). There are several types of taps that you can use. A tap could be made by boring a hole in a round chunk of wood, and carving a notch in it to receive the bucket handle, or it could be any of several commercially available varieties. Some are designed to hold a bucket, and others are designed to connect to plastic tubing. If you can manage it, plastic tubing is a lot easier because multiple taps can be drained into a common container. This reduces the amount of labor involved, but it also requires that the tapped trees be located on a hillside so the sap will flow into the container, or it requires a pump (which requires power). Power is sometimes difficult to come by in the woods.

Once the tap is in place, the sap needs to be directed into a container. This is either a bucket hung directly on the tap, or some sort of container into which the tubing is routed. The bucket should then be covered to keep out the rain and debris.

A good tree can produce a gallon of sap per day, so once you've tapped the trees, you need to keep an eye on them. Empty the buckets into a larger container until you have at least 15-20 gallons of sap (that's how much you'll need to make 2 quarts of syrup). When you have enough sap, pour it into an evaporator. An evaporator is a large shallow pan (typically 36"x24"x6") situated over a fire. The fire is often built in a steel drum which has been adapted to this use (see photo). This process will take several hours, so you'll need to wait until you have an entire day to dedicate to the task. The labor intensive portion of this task is to keep the fire stoked. Once the sap has been reduced by a factor or 30-40, it can be transferred to jugs for storage.

3. Collect a leaf and bark from two maples.

The leaves of the maple tree are fairly distinct and easy to identify. Indeed, the maple leaf is the central motif of the Flag of Canada.

Unfortunately, collecting a maple leaf is generally not something that can be done when the sap is running. Maples drop their leaves in the fall. The first signs of green made by a maple tree in spring is when it flowers. The leaves come a little later. The bark, of course, presents no such problem, as it can be collected any time during the year.

4. List two usages of the sugar maple other than maple sugaring.

Maple wood makes good firewood. Maple wood has been used for lumber and especially for making flooring, wagons, and buildings. Furniture is its most important use. The beauty of the tree adds to the beauty of our out-of-doors. It also provides shade and cooling in the summer.

5. What do you look for in tapping a maple tree?

Healthy trees, at least 10” in diameter with many branches. Tapping is best done on the east and south sides of trees where the sun warms it in the mornings and early afternoons.

6. When is the right time to tap a maple tree in the spring?

When warm days are above freezing and nights are below.

7. Name the four maples that produce sweet sap.

There are approximately 19 varieties of maple trees. Some that produce sweet sap are:

1. Sugar maple (Acer saccharum) - also known as hard maple or rock maple.
2. Silver maple (Acer saccarinum)
3. Red maple (Acer rubrum) - the second heaviest producer of syrup.
4. Black maple (Acer nigrum)
5. Ashed leaf (box elder) maple (Acer negundo)

An additional ornamental maple tree that also produces good syrup is:

• Norway maple (Acer platanoides) - stems exude a milky fluid when squeezed or when leaves plucked.

8. What is the size of the drill bit? (2 sizes)

Use a 7/16 or 1/2 inch bit to drill for the spigots. I would recommend the 7/16 inch size.

9. How can sap spoil and how is it like milk?

It may spoil if the sap is not kept cool or if it is kept too long before boiling it down. Spoiled sap has a slightly milky appearance. If boiled down it has a very dark appearance.

10. What is the maple sugaring legend?

One story is that an Indian warrior threw his tomahawk into a maple tree on a spring morning and “sweet juice” began to flow down his tomahawk, and he caught it in his hand and drank it and found it good.

Another story is of an Indian maiden who left her pottery jar at the base of a maple tree. When she returned, her pottery jar was filled with sap due to a crack in the tree.

Most likely though is that the Indians observed insects at the sap and tried it for that reason.

11. To make one quart of syrup, how many quarts of sap will you need?

It takes 30 - 40 quarts of sap to make one quart of syrup.

12. How can one tell if syrup is ready or near ready during boiling without a thermometer or hydrometer?

When boiling is started the sap looks like boiling water. As the water is boiled off the color gets darker slowly. As the sap gets close to the syrup point the bubbles get smaller. At this point the syrup tends to rise up and boil over.

Another indication is the consistency. At the syrup stage, the liquid comes off a spatula in small gooey sheets rather than drops.

With a candy thermometer, the syrup is ready when the temperature is 7° F. above the boiling point of water at your elevation. (The boiling point of water drops 1° F. for every 550 feet increase in elevation above sea level.)

13. How did the early settlers become acquainted with maple sugaring?

Maple sugaring was introduced to the early settlers by the North American Indians.

14. Visit two sugar operations.

Though some sugar houses include tours of their operation, they may charge for this. If this is not a concern, go ahead and make arrangements. If you ask nicely, or if you know someone who makes syrup on a small scale, you may be able to get a tour for free (especially if your group is willing to pitch in for a half day to keep the fires going or help collect the sap).

15. Use three recipes and display them at Investiture time.

16. Make one pound of maple sugar candy and explain how it was made.

If you continue boiling the syrup until the temperature reaches 30^o to 33^o F. above the boiling point of water (e.g. 241^o to 244^o F. in Michigan) and then stir the syrup vigorously it will start to crystallize. At this point you put it into whatever molds or containers you wish before it hardens too much in the pan.

17. What is maple wax on snow?

It is made by pouring hot syrup onto snow. As it cools it makes a delicious treat.

18. When the sap is yellow and/or moths collect in the buckets, what does that usually mean?

Time to quit for the year. The sap will produce a dark syrup of a low grade.
