I've also never tapped earlier than late January, and usually later than that. I honestly don't know if sap will be flowing tomorrow when it's going to get really warm, but I am sure we will have a solid prolonged freeze in our future and I prefer to wait for that first thaw to tap.
2014 - 8 taps, turkey fryer, 130 gallons sap, just under 2.5 gallons syrup.
2015 - 50 taps and counting.
2016 - 60 taps on 3/16 and a Bill Mason evaporator on order.
2017 - 115 taps on 3/16, homemade r/o.
2018 - 150 taps on 3/16, r/o a big help, but lots of leaks killing yield.
2019 - sticking with 150 taps or maybe less, focusing on good vacuum and less waste to increase yield. Doubling up my r/o, and made a vacuum filter that looks promising.
