What to expect: Instead of coffee beans, Seattle-based Atomo Coffee uses millet, guava, fructose, date seeds, ramon seeds, pea protein, baking soda, sunflower seeds, lemon and fenugreek to get a coffee-like flavor.
Some of those ingredients would otherwise become plant waste, according to Atomo.
Between the lines: The milk-based drinks that use Atomo's espresso alternative will cost extra, similar to the way other specialty sips, like mushroom coffees, have been sold.
Atomo's grounds sell for $20.99 per pound wholesale.
Each shop determines its own pricing, according to Atomo.
