Welcome to Kaffe Magnum Opus. We are a Specialty Coffee Roaster located in Millville, NJ. While coffee (250+ varieties) is our product, we specialize in building strong customer relationships. It's the basis of our business and why customers come and keep coming. We take the time to get to know them and create ways of using our coffee products to build their businesses. If you own a cafe or coffee shop, or work for a retail store or outlet that wants to offer its consumers the very best coffee in town, we want to get to know you. Join us for a cup of coffee and let's talk. Contact us today.
