Why Ristrettos Have Supreme Sweetness & Low Bitterness

Fruity acids, lipid emulsions, and simple sucrose solubles extract rapidly during the first 15 seconds of brewing. By cutting the shot before chlorogenic acid lactones and bitter phenylindanes extract, ristrettos deliver maximal fruit sweetness.
