What is the best way to brew 1-2 cups on a Bunn coffeemaker?

Bunn coffee makers, particularly the iconic Bunn VP17, are engineered for high-volume, commercial-grade performance. Their internal heating tanks maintain water at a constant, high temperature, allowing for near-instant brewing. However, this design philosophy presents a challenge when you only want to brew 1-2 cups. The machine’s sprayhead is optimized for a full bed of grounds; when you use a small amount of coffee, the water may channel through the bed too quickly, resulting in under-extraction.

To improve your small-batch results, start by adjusting your grind size. A slightly finer grind than you would use for a full pot can help increase resistance, forcing the water to interact with the coffee particles for a longer duration. This compensates for the reduced contact time inherent in smaller brew volumes. Always ensure your grounds are leveled in the filter to prevent the water from bypassing the coffee entirely.

Consistency is key with these machines. While the Bunn VP17 is a workhorse, it lacks the flow-rate control found in modern precision brewers. If you find your 1-2 cup batches consistently taste thin, consider using a slightly higher dose of coffee—perhaps an extra half-scoop—to boost the body and flavor intensity. This helps balance the rapid water delivery that defines the Bunn brewing experience.

Finally, remember that these machines are designed to keep a large volume of water hot. If your machine has been sitting idle, the water in the lines might have cooled slightly. Running a quick 'dummy' brew of just hot water into an empty carafe before you add your coffee grounds can help preheat the funnel and carafe, ensuring your small batch stays hot from the first drop to the last.
