I'm just guessing but I think 1/2 gal of bourbon in a 5 gal SS bbl would be too much if you want to come close to duplicating the taste of bourbon barrel aged maple syrup. On the alcohol end what would 1/10 of the alcohol be? In New York state I believe you need a special license if going 2% alcohol or more. Check the laws unless it's just for personal use.
I'm thinking most bourbon is maybe 80 proof (40% alcohol), thus you would want 1 qt max in a 5 gal batch of maple, then unless you want the kick, you might also want to mix it, then heat it to packing temp, to lower the alcohol a little too.

Dave Klish, I recently bought 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.
