Begin by trimming any excess fat from the brisket, leaving just a thin layer to enhance flavor and tenderness.
In a small bowl, combine the smoked peach rub, cayenne pepper, minced garlic, salt, and black pepper. Mix well to create a flavorful spice rub.
Rub the spice mixture evenly over the entire surface of the brisket. Ensure that each side is generously coated for an optimal flavor experience.
Place the seasoned brisket in a resealable plastic bag or wrap it tightly in plastic wrap.
Allow the brisket to marinate in the refrigerator for at least 4 hours or overnight for maximum flavor infusion.
Once marinated, transfer the brisket to your slow cooker with the fat side facing up.
Pour a touch of sherry wine over the top of the brisket to add depth and richness.
Set your slow cooker to low heat and cover it with the lid.
Allow the brisket to cook slowly for 6-8 hours, or until it becomes tender and easily shreds with a fork.
Carefully remove the tender brisket from the slow cooker and let it rest for a few minutes.
Slice the brisket against the grain to ensure maximum tenderness.
Serve your Slow Cooker Spiced Peach Brisket with your favorite side dishes, such as creamy mashed potatoes or buttery roasted potatoes.
