My policy is with Farm Family. Call them and get a quote. I have all of my insurance with them except medical. I have a farm policy and I think my Liability portion was about $500 a year. One issue there is that the insurance covers you for product liability regardless of whether you sell 4 qts a year or 1000+ gal.
Insurance is not cheap, but then just 1 lawsuit would cost you far more than 50 years of insurance bills even if you win the suit.
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.
