This is year two for me, last year was propane, this year I modified (essentially gutted) a cast iron stove and have a 2x2 pan on top. The firebox is sealed fairly well with a blower. I made my 1st boil on Sunday and got a little over a gallon. Boiling rate of slightly more than 6 GPH. The thing that I noticed when comparing the two seasons is this years batch has a slight smoky flavor, nothing overpowering but it's detectable. I have it filtered very well and it's quite clear. Just wondering if it's expected to take on the flavor when moving to wood.
