Making a profit in syrup takes lots of time and loads of work, along with doing everything right. A small operation is hard pressed to break even. To make a business of it you need several thousand taps and you need to sell a rather large portion at retail. Investments are large, sugar house, evaporator, storage tanks (stainless), filter press, vacuum pump(s), Reverse Osmosis, tubing, taps, fuel to boil, insurance, equipment to haul sap unless all sap can be run to the sugar house. These things just scratch the surface, other expenses will add to those.
I'm not saying it can't be done, but it is far from a quick income plan, the first 10-15 years it may not even break even.
That being said, on this forum there are members who make a full time income on as few as 5000 taps, but 10,000 is often considered a minimum for making a syrup operation your sole income.
Most of use make syrup because we are addicted to doing maple, it's a sickness with no known cure but rarely fatal.
Dave Klish, I recently ordered a 2x6 wood fired evaporator from A&A Sheet Metal which I will be converting to oil fired
Now have solar, 2x6 finish pan, 5 bank 7x7 filter press, large water jacketed bottler, and tankless water heater.
Recently bought another Gingerich RO, this one was a 125, but a second membrane was added thus is a 250, like I had.
After running a 2x3, a 2x6, 3x8 tapping from 79 taps up to 1320 all woodfired, now I'm going to a 2x6 oil fired and a 200-425 taps.
