This classic coffee blend might just be the very first coffee blend. It most probably dates back to the early 1500s when the Dutch, having smuggled coffee seeds out of Yemen, created plantations of coffee trees on their colony islands in the South Pacific and Southeast Asia – specifically the island of Java.
The growing conditions on Java were different from those in Yemen. The sweet, bright, acidy, and fruity coffees of Yemen, when grown on Java produced a low acid, heavy and mellow coffee. It was inevitable that these coffees, almost opposites in their best qualities, would find themselves together in a brewed cup of 16th century coffee.
The Mocha Java Blend should be a balanced and smooth coffee. The bright acidity balanced with a heavy-bodied mellowness and mouthfeel. No one knows if today’s 21st century Mocha Java Blend tastes similar to its 16th century ancestor. The planet’s ecology was very different 500 years ago. What we do know is that when an artisan coffee roaster markets a Mocha Java Blend s/he is professionally bound to use coffees from the Indonesian islands that were planted with coffee by the Dutch, and East African coffees from Yemen and/or Ethiopia.
An interesting study of Mocha Java Blends might reveal a range of interpretations as to what this blend should taste like.
