Grilled SPG Pork Loin with Mustard Crust and Dark Agave Glazed Peaches
Pork loin does not get much respect in barbecue circles, and that is usually because it gets cooked without intention. Too hot, too long, or buried under sauce to make up for mistakes. When you slow down and cook it with purpose, pork loin becomes one of the most rewarding cuts you can put over live fire.
This cook is built around control. A hot grill to build crust, then patience while the pork finishes gently off the flame. Whole grain mustard keeps the surface tacky and sharp, giving the SPG something to grab onto as the pepper blooms in the heat. It smells savory and familiar, the kind of aroma that makes people wander toward the grill without asking what is cooking.
While the pork settles into indirect heat, peaches hit the grates. Cut side down, no oil, just fruit and fire. They pick up char fast, soften quickly, and turn glossy once dark agave hits warm flesh. Sweet, smoky, and just enough contrast to make the pork shine.
This is not fancy cooking. It is confident grilling, built for Colorado evenings, seasonal fruit, and cooks who trust the fire.
Grilled Pork Loin with Mustard Crust and Dark Agave Glazed Peaches
At altitude, pork loin cooks quickly and dries out even faster if you are not paying attention. The answer is not more sauce or lower expectations. The answer is timing, zones, and knowing when to step back.
A two-zone grill does the heavy lifting here. Direct heat builds flavor and texture, while indirect heat finishes the pork evenly from edge to center. Whole grain mustard acts as more than a binder. It adds bite, balances the meat, and keeps the seasoning locked in place as the crust forms.
The peaches are cooked the same way you cook everything else over fire. Let the heat do its job. Grill them hard on the cut side, then flip and glaze while they are still over the flame. Dark agave melts, tightens, and clings instead of dripping away. The sweetness stays controlled, never crossing into dessert.
This is Colorado barbecue thinking. Simple ingredients, live fire, and confidence built from paying attention instead of rushing.

Ingredients
- 1 pork loin roast, about 2 to 2 1/2 pounds
- 2 tablespoons whole grain mustard
- 1 1/2 tablespoons Revolution Barbecue SPG$
- 4 ripe peaches
- 3 tablespoons dark agave nectar
- 1 teaspoon apple cider vinegar
- 1 tablespoon butter
Directions
- Prepare the pork loin: Coat the pork loin evenly with whole grain mustard, then season all sides with Revolution Barbecue SPG$. Let the pork sit at room temperature for about 15 minutes while the grill heats.
- Set up the grill: Preheat the grill for two-zone cooking with one hot direct heat zone and one cooler indirect heat zone. Allow the grates to fully heat for about 10 minutes.
- Sear the pork: Place the pork loin over direct heat and grill for about 8 to 10 minutes total, turning every 2 to 3 minutes until a well-developed crust forms on all sides.
- Finish over indirect heat: Move the pork loin to indirect heat, close the lid, and continue cooking for about 25 to 30 minutes until the internal temperature reaches 138 degrees Fahrenheit.
- Grill the peaches: While the pork finishes, halve and pit the peaches. Place them cut side down directly over the hot zone and grill for about 3 to 4 minutes until caramelized and well marked. Flip the peaches cut side up, drizzle with dark agave, and continue grilling over direct heat for about 2 to 3 minutes until glossy and tender.
- Rest the pork: Remove the pork loin from the grill and rest uncovered for 15 minutes to allow juices to redistribute.
- Make the glaze: While the pork rests, warm the dark agave, apple cider vinegar, and butter together in a small pan over low heat for about 3 minutes until smooth and combined.
- Slice and serve: Slice the pork into thick medallions and serve with the grilled peaches. Spoon a small amount of warm glaze over the peaches just before serving.
