From the Ranch

Cooking, baking, grilling, favorite recipes, and occasional observations from life in wine country.

Curiosity has always been my favorite occupation.

I’m Marci Norkin-Schoepel—a retired mechanical engineer and contractor, nerd, winemaker at heart, Graduate Gemologist and gemcutter, BBQ and grilling enthusiast, traveler, and problem solver. I enjoy turning ideas into useful things and sharing what I learn along the way, usually by creating them in Inventor and Fusion 360, then printing them with my Ultimaker 3D printer.
