Revolution Gelato Plant-Based Organic Pint - French Press Coffee: We make an in-house 24-hour cold brew with so much coffee that even after adding the rest of the gelato ingredients, itâs as strong as a cup of brewed coffee. The single-origin coffee we use comes from a small family-run farm in Nicaragua. We love their coffee! Itâs a full roast with big body and earthy, chocolatey notes.
