  • My Favorite Topic… BBQ with Dr. Gregg Rentfrow
    May 14 2025

    On this episode of the Maine Farmcast, Dr. Knight sits down with Dr. Gregg Rentfrow, Professor of Meat Science and State Meat Specialist for the University of Kentucky, to discuss one of my favorite topics, barbecue.

    My BBQ journey began when I was a teenager showing horses in the South with my parents and going on road trips across the country with my dad. We got to experience the old school “mom and pop” BBQ stands and shops before BBQ became a national phenomenon. Back then, BBQ was less pretentious. There were no frills or fancy restaurants. Usually just a shack with folding tables and prepackaged hamburger buns. I started learning how to BBQ when I was in grad school, which led me down a rabbit hole I still haven’t escaped.

    This week, Dr. Rentfrow and I are going to discuss some tips and tricks to level up your BBQ game. If you would like to learn more about BBQ, contact your local extension office and ask if they can offer in person classes!
