The Philippines grows four coffee species: Robusta, Arabica, Excelsa, and Liberica. We cold brew each one on its own so you can taste the difference side by side. This set has five 500 mL bottles: one of each species, plus Buklod Blend, a mix of all four. That's 2.5 liters, about 10 glasses. Medium roast, never dark. No sugar, just coffee and water. Pour over ice, or add a splash of milk. Keep refrigerated once it arrives. Shake gently before pouring.
