Be sure to order this one in whole bean form so you can see the unusual bean -- single, small round bean holding so much flavor. Peaberry coffee beans occur when coffee is grown in dry areas where the soil is low in trace elements of Boron. The tree responds by growing fruit that has only one round seed, instead of the typical two flat seeds. The "plus" designation refers to the coffee being of highest quality due to meticulous preparation and sorting. The cup itself is creamy and balanced with citrus, floral and chocolate flavor notes.
