Brooklyn-based Angels’ Cup Coffee is launching their latest app designed to help coffee drinkers refine their palettes and discover new types of gourmet coffee.

In blind tasting, the samplers do not know what they are tasting, so that they are better able to judge flavor and character without preconceived notions. For $7.99, four 1-ounce, “blind” coffee samples, are delivered to users based on their weekly, bi-weekly, or monthly subscriptions. The Angels’ Cup app lets coffee enthusiasts sample an unknown type coffee, record notes on their experiences, and then enter a code into the app that compares their flavor palette with the roast master. Only then does the customer find out which type of coffee they sampled; and if they liked it, they can order a whole bag directly from the roaster.

The app comes with easy-to-use tools, such as the flavor wheel to help coffee tasters visualize and pinpoint distinct aromas and tastes. The app saves and records notes for future reference, allowing coffee drinkers to develop their coffee expertise and make informed choices when purchasing their next coffee.

The new app is coming to the scene as the “third-wave” trend in coffee drinking is taking off. This cultural shift is focused on lighter roasts that showcase the unique flavor profiles of different origins, and also supports environmentally sustainable brewing methods that use affordable, low-tech, single-cup brewers.

“Angels’ Cup really isn’t about the coffee at all; it’s about the customers and their own personal journeys to develop a more refined sense of taste. It’s also about building a community around the shared experience of tasting the subtle flavors in a cup of coffee,” says company co-founder, Jeff Borack.

Unlike other companies that simply focus on curating and shipping to customers, acting as middlemen between the roaster and customer, Angels’ Cup’s main objective is to help customers’ develop their palate with their educational app, and to provide the world with better, more affordable, and environmentally sustainable coffee.

“We used to go to public cuppings (where roasters invite the public in to sample coffees side-by-side). What got people really excited wasn’t just amazing coffee. It was finding someone who tastes the same thing as you—maybe bananas in the cup, or the smell of marigolds. We’re recreating that experience on a massive scale,” adds Borack.
