World champion barista James Hoffmann and Cometeer partnered to conduct a first-of-its-kind coffee taste test. Cometeer shipped 5000 coffee kits across America. Kits contained four different coffees - pre-extracted and flash frozen. Tasters melted and diluted the coffee capsules for a largely identical tasting experience. Tasting and ratings were conducted blind [1]. After survey responses were collected (provided data), some attributes of the coffee were revealed [2].

Coffee types revealed post-survey:

• A. Light roast, washed process
• B. Medium roast
• C. Dark roast
• D. Light roast, natural process (fermented, funky/fruity)

Coffee types were selected for three main questions:

• 1. Roast level preference (light [A] vs medium [B] vs dark [C])
• 2. Preference for fruitiness (washed [A] vs natural [D])
• 3. Most popular coffee
