No sap running yesterday. We emptied the little bit of sap from the initial drilling of the taps and we are waiting for the next freezing night which could come this Wednesday night. We ran our CDL 600 gallon per hour Reverse Osmosis unit for the first time yesterday and I must say it is the first good nights sleep I have had since I started making maple syrup. No more cooking late in the wee morning hours. We also switched to the CDL anti-foam powder which did a much better job than butter. No boil overs!! Buds on the silver and red maples have broke but the sugar maples still look good and we anticipate a great season as I look at the 21 day forecast.
