I've got 116 taps this year and can go up to 250 next year. I think once I scale up next year I'll have to build some sort of wood fired boiler. It's been interesting learning about where the biggest efficiency gains can be found as I scale up. Last year I totally redesigned my strategy around which trees to tap and how I went about collecting. It ended up saving me tons of time. When I only had 30 taps, the collection process didn't seem that important.
