With the exception of a few bad storms, this has been a fairly mild winter for most of the US and Canada. The warmer temperatures mean fewer snow days, lighter jackets and an early start to maple syrup season.
The season typically begins in early spring when it is still below freezing at night but slightly warmer (40F or higher) during the day. The reason for the time frame is that the sap levels are at the peak at that point in the year and the daytime temperatures allow it to flow more freely from the tapped trees. Mild winters produce the same effects, although the sugars in the sap are not as intensely concentrated as they will be later in the year. One of the primary reasons that a farmer might begin to harvest sap early, relying on a processes to concentrate the sugars in the sap, is to stay in business, although some traditionalists will turn up their noses at the practice.
'Some people say it isn't natural to make a hole in a tree during the winter, but it is also unnatural to tap trees during the spring,' said one Canadian farmer, noting that only a small portion of the sap is taken and that the trees heal rather quickly and that "only producers who've never tried making syrup in winter would criticize the practice."
