Hawaiian Coffee Regions Compared: Kona, Ka'u, Maui and More

Kona is the name most people know, but it is only one of several coffee-growing regions in Hawaii. Coffee is also grown in Ka'u, Puna and Hamakua on Hawaii Island, and on Maui, Kauai, Molokai and Oahu. Each region has its own landscape and its own name on the label, and Hawaii has some of the most detailed coffee labelling rules anywhere. This guide compares the regions and explains how to read a Hawaiian coffee label so you get exactly what you are paying for.

The regions at a glance

All of these regions share Hawaii's unusual position for coffee: further from the equator than most coffee lands, so cooler growing conditions arrive at more modest elevations, and many farms sit on young volcanic soils. Within that, rainfall, slope, sun and elevation vary a great deal from one district to the next.

How the regions tend to differ in the cup

Hawaiian coffee is produced by many small farms using different varieties and processing methods, so the farm matters more than any regional stereotype. With that caveat:

• Kona is the best-known style: often described as medium-bodied and sweet, with soft acidity and nutty or caramel notes. Our comparison of Blue Mountain vs Kona sets it against Jamaica's most famous coffee.
• Ka'u coffees come from the slopes of the same volcano as much of Kona but in a different district and climate, and they have built a separate identity on the label.
• Maui, Kauai, Molokai and Oahu coffees range widely, from classic washed coffees to experimental lots, depending on the farm.

If you are comparing regions, look for the farm name, variety and processing method on the bag. Those details, explained in our guide to reading a coffee label, will tell you more than the island name alone.

How Hawaii's coffee labelling law works

Hawaii Revised Statutes section 486-120.6 sets rules for the identity statement on roasted or instant coffee made in whole or in part from Hawaii-grown beans. In broad terms:

• Coffee from one Hawaiian origin is labelled with the geographic origin followed by the word "Coffee", for example Kona Coffee or Ka'u Coffee, and the origin may be preceded by "100%".
• Coffee from several Hawaiian origins has its own required wording, including the term "All Hawaiian". Under rules that took effect on 1 July 2024, the Hawaii Department of Agriculture explains that "All Hawaiian" requires coffee that is entirely grown and processed in Hawaii.
• Blends of Hawaiian and non-Hawaiian coffee must state the percentage and origin of the Hawaiian coffee followed by "Coffee Blend".
• Type size is regulated too, so the words cannot be split up or the percentage hidden in tiny print.

The blend rule is changing in 2027

For years, a coffee could be sold as a Kona blend, or a blend named after another Hawaiian origin, with as little as 10 percent of that coffee, as long as the percentage was stated. In 2024 Hawaii's legislature passed House Bill 2298, which Governor Josh Green signed. It keeps the 10 percent minimum through 30 June 2027 and, from 1 July 2027, requires a coffee blend that uses a Hawaiian geographic origin name to contain at least 51 percent coffee by weight from that origin.

For shoppers, that means two things. Until mid-2027, a regional blend can still be mostly non-Hawaiian coffee, so read the percentage. After the change, a regional blend will have to be majority coffee from the named origin. Either way, "100%" followed by the origin remains the clearest sign you are buying only that coffee. Our guide to single origin vs blend coffee explains when a blend makes sense.

Grades for Hawaiian coffee

The Hawaii Department of Agriculture also sets grade standards for green coffee. For Kona, the familiar grades run from Extra Fancy and Fancy to No. 1, Select and Prime, with separate peaberry grades. Grades are based on bean size, defects and moisture; they describe the physical quality of the green coffee, not a flavour you will prefer. Our guide to peaberry vs regular beans explains why peaberries are graded separately, and coffee bean screen sizes explains the size side of grading.

How Hawaiian names compare with other protected origins

Hawaii protects its origin names through state labelling law. Jamaica protects Jamaica Blue Mountain through regulation and certification by JACRA plus registered trademarks, and Colombia protects Café de Colombia as a geographical indication. These systems work differently, but they share a purpose: to stop famous names being used on coffee that does not come from the place. Our explainer on coffee geographical indications compares them.

How to choose a Hawaiian coffee

• Start with the identity statement. "100% Kona Coffee" or "100% Ka'u Coffee" means only that origin. A blend must show a percentage.
• Pick the region, then the farm. Try two regions side by side, ideally from farms that list variety and process.
• Check grade and roast date. A fresh Fancy or No. 1 can easily beat a stale Extra Fancy.
• Brew for clarity. Most Hawaiian coffees shine at light-medium to medium roast in pour over or a good drip brewer; see our brewing guide.

If you enjoy Kona's gentle style, Jamaica Blue Mountain is the natural comparison. Our shop carries 100% Jamaica Blue Mountain if you want to taste the two island coffees side by side.
