It’s sourced MGP, but barreled and aged by Cathead in MS. Something about the heat and humidity down there really brings out the flavor.
If you can find a bottle, buy it. I’ve tried quite a few quality Top Shelf allocated bottles in my life, Stagg Sr, Pappy, Willet Green Top, Rock Hill and this juice is exceptional. I think they only made 1100 bottles total and was mainly released in the southern states.
