Former World Barista Champion James Hoffman virtually hosted the Great American Coffee Taste Test, during which thousands of people simultaneously blind-tasted the same four coffees. Hoffman has published a video summarizing the results, as well as a spreadsheet of anonymized survey responses from 4,000+ participants. It includes tasters’ demographics, general coffee drinking habits and preferences (https://bit.ly/gacttCSV+), assessments of the four coffees, and more.
