Collecting Birch Sap for Syrup, Part 1

In 2013, I wrote a blog article about collecting birch sap in the spring to make beer.  Since that topic has continued to attract hundreds of readers, particularly this time of year, I thought an update might be in order, especially now that we have “amped up” collection to hundreds of gallons and now enjoy the delicious syrup, too.

Whereas collecting a few gallons of sap from a few trees is very cheap and easy to do, and nutritionally/flavorfully worthwhile for residents of a boreal forest, collecting enough and cooking it down to syrup is a huge endeavor, perhaps better suited to a business or affinity group. Below is our experience over several years.

The previous collection method

In  2013, we picked four trees close together, tapped them, and let the sap drip into a vinegar bottle we bungee corded beneath each tap and thus collected an initial 2.5 gallons. Because we were so pleased with the flavor, nutritional value, and versatility of the sap, the next two years, we “uppped” our take to 15 gallons, collected by a length of food grade tubing connecting each tap to a five gallon bucket at the foot of each tree.  We collected our target amount in only 3 or 4 days. Easy in, easy out.

Five gallons were immediately deployed as the liquid (replacing water) in a batch of home brewed spring beer.  (Bryan reports that he could not discern a difference in flavor or texture from the 2013 batch of 1/2 water and 1/2 sap, but he enjoys the contrast to his chimay recipe made with 100% water.)  It  has an initial taste of wood and banana.  The banana flavor recedes, but a pleasingly light woodiness and sweetness remain.

Winter Ski Plane Challenges in Remote Alaska

Winter flying introduces a number of duties and challenges not encountered in warm weather, but there are some advantages, too. Below are a few anecdotes from our ski plane flights, as we fly to and from our remote home in the Alaska Bush.

PRE-FLIGHT:
Warm Up:  Like any car in cold climates, we have to warm up the plane, since we do not store it in a hangar.  The day before a flight, Bryan unravels a long blue electrical cord  stored behind a cedar loveseat on our front porch, and threads it from an electric plug on the outer wall, down through the snow to the frozen lake where we have tethered the plane to two boards frozen beneath four feet of lake ice.  With the cord, he charges the plane's battery, since its performance degrades in cold temperatures.

The next day, an hour before the flight, we pre-heat the plane. When we first bought the aged plane (a 1954 Piper PA-20), the owner gave us an ancient Red Dragon heater that he had not used often.  To utilize it, we drag it down to the plane in a little black plastic sled, along with a 20 lb propane tank, a board (as a flat, hard surface for the heater), a battery charger, and a five foot long heating tube (that you shove up into the engine compartment).  Unfortunately, the tube  was so perforated with tiny holes that it took us 45 minutes to pre-heat the engine.  Not a fun wait at freezing temperatures!  Once we figured out the problem, we bought a new one for $200 that cut the time down to 15 minutes.  Well worth it.   Until... one day, when the low temperatures and the low voltage battery charger conspired to cause a near emergency.  The charger was underpowered for the job on a particularly cold day.  It had enough power to generate a hot flame but not enough to push the heat through to the plane's engine.  The tube caught fire!  We lacked a handy fire extinguisher but Bryan yanked it out of the cowling and tossed it on the snow, where the fabric sheath disintegrated into fluffy, gray ash. We learned several lessons that day.  One is to keep a fire extingisher with the dragon heater.  Another is to make sure that the bungee cords of the cowl cover are totally detached from every single hook for a rapid whisk away from the nose cone.  A  third is to utilize my snowmachine instead of the modest battery charger for future power (and the added convenience of grooming the landing strip after he departs).
