The Bee-Friendly Garden

The Grovestead's Bee Friendly Garden

A long time in the works, I am happy to announce our Bee-Friendly Garden seed collection is now on sale! This collection of annual and perennial seeds were hand picked for their visual aesthetic, fragrances, and ability to attract and feed honeybees.

The Bee-Friendly Garden: Purple Coneflower

The Bee-Friendly Garden: Sunflower

The Bee-Friendly Garden: Sweet Alyssum

Becca explained it this way on her blog:

I was thinking about how excited I get when I’m driving on an interstate and see one of those blue signs with a little sign for a Jimmy Johns. That’s my favorite place to eat on a road trip. And how basically each person who plants honey bee friendly flowers is setting up a little buffet for honey bees. Bees will fly for miles in a day looking for good pollen and nectar. I’m imagining them getting just as excited to find our little bee friendly gardens as I am when I find a Jimmy Johns.

The Beekeepers

We have a limited quantity made up, so if you are interested in starting a bee-friendly buffet this Spring, be sure to place your order soon!

Evaporating sap and making maple syrup

Evaporator boils down the sap

The trees are tapped and the sap is flowing. Finally its time to turn those gallons of sap into delicious maple syrup! If you have not already read part 1 and part 2 of this series you may want to go back and do that first. In this post I’ll cover the evaporating process and finishing and bottling maple syrup.

Evaporating the sap

By far the most time intensive part of maple sugaring is the evaporating. Sap is 98% water, give or take, so depending on your setup you can spend many dozens of hours and an obscene amount of wood getting the sap boiled down to syrup. The last two years I hodgepodged together a cinder block evaporator. It worked, but was terribly inefficient and a bit dangerous. This year I had plans to build my own steel box evaporator and lucked out when a local welder offered to sell me his own at a great price.

Wood-burning firebox

The firebox holds a tremendous amount of wood and the stainless steel pan can hold up to 15 gallons of sap at a time, although it is more efficient to boil a shallow than deep pan.

The goal is to keep a roiling boiling for hours on end. Because it takes so much wood and takes so long to get everything heated up, I usually wait until I have 20 gallons of sap collected before evaporating.

Sap vigorously boiling on the evaporator

The time required varies greatly by the weather. Colder, windy days take longer than calm, sunny ones. Next year I’ll make better use of firebrick and concrete blocks to insulate the steel from the wind and focus as much heat as possible to the bottom of the pan.

While the sap is boiling I have a second pan warming sap on the edge of the evaporator. Pouring cold sap into a boiling pan would kill the boil and slow down the evaporating. So everything you can do to pre-heat the sap saves time in the end.

Warming pan warms up the sap before being added into the main pan

As the sap boils impurities foam up to the surface. Every so often I use a strainer to scoop off the foam.

Straining foam out of the sap

That’s pretty much all there is to it. Feed the fire, add sap, strain. Repeat. The evaporating is done when the sap is reduced to a dark brown color and the sap/syrup is thickening. It’s usually pretty obvious when the consistency of the sap has changed.

Sap is reduced and ready for finishing

Because the final stages of evaporating need to be tightly controlled, most people will “finish” the sap indoors on a standard range.

My new evaporator has a nifty drain spout. To get the sap/syrup out all I need to do is turn the spigot.

Draining the syrup out of a spout on the evaporator pan

Finishing the sap

The final stage of making maple syrup involves getting the syrup to the right consistency. There are a couple of ways to do this. You can either measure the buoyancy with a hydrometer or use a candy thermometer to measure the boiling temperature. The boiling pot has to be watched closely because once the sap turns to syrup it can boil over quickly. I lose lots of syrup this way every year, despite my best efforts.

I like to boil at a medium-high heat taking periodic measurements with the hydrometer.

Hydrometer measures the density of syrup

Periodic checks using the hydrometer ensures the exact right density

Measuring 32 baume on the hydrometer means the syrup is done

After ladling syrup into the cylinder container, I drop the hydrometer in and it floats to the measured density. A reading of 32 Baume (or 66 Brix)—the red line—means the syrup is done. Alternately, a candy thermometer reading of 7.1 degrees above the boiling point of water (219.1 for most of us) is considered finished syrup.  It’s important that the measurements be accurate, otherwise the syrup may be too weak and not store well or be too dense and crystalize. That’s why finishing inside on a controlled stovetop is preferred.

Filtering and bottling the syrup

Now the syrup is complete and ready to bottle. First the syrup needs to be filtered. Some people use cheesecloth, but I prefer a dish towel folded in half (used only for maple syrup). In my experience cheesecloth is too porous and allows too many particulates through.

Filtering the finished syrup

I can usually filter 2-3 pints at a time into a 2-quart bowl. Then I pour into pre-sterlized canning jars and screw on the lids.

Pouring filtered maple syrup into jars

Syrup does not need to be sterilized in a water bath like other canning products. As long as the containers are sterile the boiled and filtered syrup will remain extremely hot for a very long time and create a tight seal as they cool down. Tip: screw the lids down as tight as possible, then the next morning screw them a little tighter, if you can. I’ve had some jars lose their seal days or weeks later, presumably because the lids were not as tight after everything cooled down.

When you do open a sealed jar, it has to stay in the refrigerator from that point on. Pure maple syrup is different from the brown-dyed corn syrup you find in the grocery store and will spoil if not refrigerated after opening. Properly sealed syrup will last at least one year, but likely won’t make it that long once you have a taste for it.

Last step: cook up some pancakes and enjoy.

Enjoy your pure maple syrup with pancakes and a good cup of coffee.

 


How to tap a tree

Drill about 2 inches deep

In my previous post, I discussed the basics of getting started with your own maple sugaring operation. In this post, I wanted to show the step-by-step process of tapping trees and collecting sap.

The tradition of tapping trees for syrup and sugar dates back to before the first settlers arrived. It was Native Americans who discovered that trees could be tapped for sugar. They originated the techniques of using wooden spiles to drain sap from trees and dropping heated rocks into troughs to boil off the water. Native Americans taught their techniques to the Pilgrims and early settlers as they arrived. Reportedly, maple syrup was on the menu at the first Thanksgiving in 1621.

After 400 years, the process hasn’t changed much. We now use steel vats and power drills but the basic method of poking holes in trees, inserting a spout, collecting the sap and boiling it down is the same.

Drilling and Tapping

The first step after you have identified a tree is to drill the hole. It doesn’t matter much how high off the ground you tap, except that you will have the most sap flowing from the trunk of the tree upward. I always try to place the tap about waist high. Some people say to tap on the South side because its sunny. Others say to tap on the North side because “the pressure builds up there”, whatever that means. I have never noticed a difference in any of the sides. I always try to guess where the tree needs the most sap and place the tap there. For example, if the trunk splits I drill under the healthier of the trunks. But honestly I can’t say that’s a guarantee either.

When you drill the hole, angle the drill slightly upward (but not too steep or the sack won’t hang correctly), and drill about 2 inches deep.

Angle of drill should be slightly below horizontal

A piece of tape wrapped around the drill bit lets you know how deep to drill.

Next set the spout in place and hammer in. It needs to hold over 30 pounds, so be sure to tap it in far enough.

Hanging the buckets (or sacks)

Next step is to add your sap sacks. I like using sacks instead of buckets because they hold a ton of sap (4 gallons) and don’t take up any storage space. The assembly is simple: the bag is wrapped around an inner rim piece, then the rim is slid into the holder.

Finally the sack is hung on the spout.

Make sure the sap is flowing where its supposed to.

Collecting the sap

After the trees are tapped and the bags are hung, it’s time to wait. It can take take several days for the bags to fill with sap.

If the temperature drops, the sap may stop flowing altogether. If the days are warm and sunny, you might encounter a “run”, where a significant amount of sap is collected over a short period. This year it took about 2 weeks to collect the first 40 gallons of sap, but the next 50 gallons were collected in 2 days! The trick is not to be gone on vacation during a sap run.

Collecting sap from the bags

Once a day I check all my taps and pour off any bags that are over half full. I store up the five-gallon buckets in our garage until I have enough to spend a day evaporating (usually 20 gallons).

Emptying sacks into buckets to store

Sap runs always seem to catch me off guard and I find myself running to the hardware store to buy extra buckets. But eventually the season comes to an abrupt end and all that running around and hauling buckets is done, until next year.

This year we were in the middle of a run, and we had run out of buckets. We had 60 gallons stored and no time to evaporate. Then I happened to taste the sap from one of the trees and could tell it was changing flavor. I went to all the other trees and tasted the same difference. It was “buddy” sap, a slightly earthy (some say bitter) flavor. I went back to the house and told Becca our storage dilemma was solved—the season was over. As abruptly as it started, the maple sugaring season had ended.

That covers tree tapping and sap collection. In my final post I will show how to use an evaporator to boil down all those gallons of sap into sweet, pure maple syrup.

 


Getting started with Maple Sugaring

Getting started with Maple Sugaring

This is our third year tapping trees to make maple syrup, and each year when the sap begins to flow I am thrilled and amazed. To collect gallons of sap from trees growing in your own yard and turn it into delicious, pure syrup is truly an amazing experience—another everyday miracle on the farm. We’ve had so much fun over the years we even threw a tree-tapping party last year.

We’ve also had a lot of people interested in starting this hobby for themselves. I wrote this post to answer a lot of the questions we get asked about how to get started.

What you need and where to get it

As with everything, there are many ways to get the job done. This is just what I prefer, having found it to work reliably over the years:

  • Battery-powered drill (or a really long extension cord)
  • 7/16-inch drill bit – $8 at Menards
  • 7/16″ Hookless Aluminum Spout – $3ea at Leader Evaporator
  • Sap Sak Holder – $7ea at Leader Evaporator
    (I have also seen these at Mills Fleet Farm for 1/2-price after the season is over)
  • Sap Sak – $0.55ea at Leader Evaporator
  • Hammer

The bummer is that about the time you are interested in tapping maple trees, so is everyone else and many suppliers will be sold out for the season. So be sure to order your supplies well ahead of Maple Sugaring season (which usually means before March).

How to identify maple trees

Maple leaves are perhaps the most recognizable leaf in the world. It’s the only leaf that has it’s own national flag. But that won’t help you much in the middle of winter when there are no leaves. You’ll have to look at other things like bark and branches to get a clue.

There are four common types of maple trees for syrup production, and each one has it’s own identifying characteristics:

  • Sugar Maple
  • Silver Maple
  • Red Maple
  • Boxelder (yes, it’s a maple tree)

On our property, we have only Silver Maples. They are characterized by early buds on the tips of branches and wide, flat, silvery bark.

Each tree produces a different amount of sugar content, with “Sugar” Maple being the highest. Higher sugar content is desirable because it means less water needs to be evaporated to produce syrup. Our Silver Maples are almost as good as Sugar Maples, on average producing 1 gallon of syrup for 30 gallons of sap (3-4% sugar content).

When to tap trees and for how long

Sap begins to flow during late Winter when temperatures rise above freezing. For us, this means sometime in March. I’ve found the best setup for sap runs is freezing temperatures overnight and above freezing temperatures during the day, for several days in a row. If you see that setup in the forecast, it’s a good time to get out and tap your trees.

The actual season can last anywhere from 2 weeks to 2 months, again depending on the weather. You basically have until the tree starts budding. Once that happens, the flavor of the syrup will be tainted and won’t taste good (known as “buddy sap”). If the weather turns cold after the sap beings to flow, this will inhibit leaves from forming and prolong the season.

There’s a chapter in Laura Ingalls Wilder’s Little House in the Big Woods, entitled “Sugar Snow”. A thick snow falls late into Spring and Laura is excited because means the season will be prolonged and there will be more sugar that year.

A tip for selecting trees

Here’s something I was surprised to learn: not all the maple trees you tap will produce sap. In any given year, only about half my trees ever produce sap. I still don’t understand why. They appear to be healthy and clearly sap is getting to the leaves. I keep trying different tap placements, but it doesn’t seem to matter. Some trees just won’t produce well. On the other hand, you’ll find some trees to be abundant producers. I’ve got two trees that produce more sap than 10 other trees combined.

This year I tried something different. Since my spouts are limited, I drilled holes in all my trees but didn’t hammer in the spouts until after they began to drip.

Sap leaking from drilled hole

That way I’m not wasting spouts on trees that will never produce.

What to do with the sap

Every day I check the bags. I empty anything over 1/2 full into a 5-gallon bucket then store it in a cool place until I have enough to evaporate. Once I have 20 or so gallons collected, I’ll fire up the evaporator and spend several hours boiling it down.

It’s important not to let the sap sit for too long or it can begin to spoil. A few days is fine, but anything more than that should be evaporated or stored in a refrigerator.

Does it hurt the tree?

No. As long as the tree is large enough to support tapping, the holes you drill will fill in after you remove the spouts.

Last year's hole has filled in

Just make sure not to drill in the same place each year.

Any trees that are at least 12 inches in diameter can be safely tapped. Larger trees over 20 inches can support 2 taps, and 27 inches or larger can support 3 taps.

And just to prove that collecting sap is not harmful, take a look at these pictures from a maple tree we tapped this afternoon.

Sap is leaking from a maple tree

If you don’t tap a tree, it will likely leak sap anyway. This tree was quite literally bursting at the seams. The tip of every branch was dripping with sap. I was getting rained on while standing under this tree.

When we tapped the tree to add spouts, it immediately started gushing sap. I wouldn’t be surprised to find full bags in the morning.

That covers the basics and I hope answers most of the questions about tree tapping and maple sugaring. In my next post I’ll show the step-by-step process of actually tapping the tree and collecting sap.

 


Baby chicks growing fast

Our baby chicks, Cocoa and Clove, were born 2 weeks ago and are growing fast! In fact they are quickly outgrowing their brooder and we’re now looking for a bigger box.

We try to give them time each day outside the box to stretch their legs and flap their tiny wings.

It will probably be another month indoors. The other chickens will be properly introduced after the snow melts and there’s plenty of space for everyone.

Spring is coming, though! Temps reached about 50 degrees today and everyone was outdoors to enjoy it.
