Melt butter in a large saucepan over medium heat. Add onions, and saute until translucent, 3 to 5 minutes. Add garlic, jalapenos, chili powder, and coriander. Saute stirring occasionally to prevent sticking, until fragrant and vegetables are softened, about 3 minutes more.
Add coffee, Worcestershire sauce, soy sauce, tomato sauce, vinegar, lime juice, brown sugar, and cider. Reduce heat, and simmer mixture gently for 30 minutes to infuse flavors.
Remove from heat, and let cool slightly. Puree in batches in a blender or food processor until smooth.
