5 LB Resealable Bag w/ Valve. Polished Vietnam Robusta is made with coffee beans from the Highlands of Vietnam. It has a spiciness mixed with floral notes, and a light acidity. Our light roast leaves the natural mixture of this coffee bean's flavors more detectable. Note that this is the only robusta coffee offered. This is meant as a low cost alternative to arabica coffees or a nice addition to espresso for crema purposes.
