Hawaii is synonymous with high-quality coffee, with Kona coffee often stealing the spotlight. But beyond the lush slopes of Kona, tucked away in the islands’ nutrient-rich volcanic soil, exist rare coffee varietals that often go unnoticed. These unique beans offer coffee lovers an opportunity to experience flavors that are just as vibrant and memorable as a sunrise over the Hawaiian coastline. Let's uncover the hidden gems of Hawaiian coffee, their distinct qualities, and how you can enjoy them to the fullest.
What Makes Hawaiian Coffee Unique?
Hawaii is the only U.S. state where coffee is cultivated on a commercial scale, and its climate is ideal for growing extraordinary beans. The combination of volcanic soil, tropical rain, and consistent sunshine creates an environment unlike any other in the world. These conditions are the backbone of Hawaiian coffee's unique flavor profiles. While Kona coffee is the most famous, Hawaii’s coffee-growing regions—from Kaʻū to Maui, Oʻahu, and Molokaʻi—are home to lesser-known varietals that deserve attention.
Rare Hawaiian Coffee Varietals to Discover
1. Kaʻū Coffee

Nestled south of the Kona district, Kaʻū is quietly producing some of the best coffee Hawaii has to offer. Kaʻū coffee beans are often described as having a complex profile, with tasting notes of brown sugar, tropical fruit, and a hint of floral undertones. Kaʻū coffee has gained international recognition in recent years, winning awards for its exquisite balance of flavor and acidity. Shop Ka'u Coffee.
2. Maui Mokka

One of the most unique varietals, Maui Mokka, grows exclusively on Maui. These beans are tiny, resembling chocolate-covered espresso beans, but their flavor is anything but small. Maui Mokka is celebrated for its bold and fruity profile, often featuring notes of wine, dark chocolate, and spice. It's a dream for those who love vibrant, full-bodied coffee.
3. Oʻahu Waialua Coffee

Grown on the island of Oʻahu, Waialua coffee is lighter in acidity with nutty, earthy tones and hints of cocoa. The North Shore’s microclimate gives these beans a softer, smoother taste. While Waialua coffee may not have the intense boldness of other Hawaiian beans, it offers a mellow brew that’s perfect for casual sipping.
4. Molokaʻi Coffee

The island of Molokaʻi may be small, but its coffee makes a big impression. Molokaʻi coffee varietals are full-bodied with a velvety texture and tasting notes of caramel, spice, and a touch of red fruit. These beans are grown with care on family-run farms, making them a true labor of love.
5. Kona Peaberry Coffee

Kona Peaberry may not sound rare, but this special bean is a one-in-a-thousand find! Unlike other coffee cherries, which contain two beans, peaberries are single-seeds, resulting in a naturally concentrated flavor. The taste is smooth yet vibrant, with hints of citrus and floral undertones.

Why These Varietals Deserve Attention
Rare Hawaiian coffee varietals are treasures not just for their unique flavors, but for how they exemplify the connection between cultivation and culture. These beans are often farmed on small, independent estates hand-tended by farmers who pour their aloha spirit into every harvest. Supporting these rare coffees means you’re also contributing to the island’s sustainable farming practices and the preservation of rich coffee traditions.
Brewing Tips to Experience Hawaiian Coffee at Its Best

Brewing these rare coffees is about letting their distinct flavors shine through. Here are some tips to bring out the best in your cup:
- Grind Fresh
Always grind your beans just before brewing to preserve their fresh, aromatic qualities. Use a burr grinder for an even grind—you’ll be surprised at how much better it tastes.
- Use Filtered Water
Hawaiian coffee's flavors can be delicate, so avoid tap water, which may introduce unwanted minerals. Filtered or spring water is ideal.
- Experiment with Brewing Methods
For Kaʻū or Waialua coffee, try a French press to emphasize their richer, rounder flavors. For Maui Mokka or Molokaʻi coffee, a pour-over brewing method can highlight their fruity and wine-like notes. Peaberry coffee shines with an Aeropress or drip coffee maker, both of which create balance and clarity.
- Pay Attention to Ratios
The standard coffee-to-water ratio is 1 to 15–17 (one gram of coffee per 15–17 grams of water). Adjust to your taste, but start here to avoid overpowering the nuanced flavors.
- Drink Mindfully
Finally, take a moment to truly enjoy the depth and complexity in each sip—it’s not just coffee; it’s a piece of Hawaii’s soul.
Where to Find Rare Hawaiian Coffee
Sourcing these gems can be a little tricky, but the hunt is worth it. Specialty Hawaiian coffee shops and roasters often carry limited batches of these rare beans. You can also purchase directly from local farms, many of which sell online. For example, Coffee Gallery Hawaii offers a curated selection of distinct Hawaiian blends and may help connect you to some of these rare varietals.
A Final Sip

Rare Hawaiian coffee varietals are not just beverages; they’re an invitation to explore the diversity and richness of Hawaii's coffee culture. Each bean tells a story of its origin, its grower, and the land that nurtured it. If you’re looking to expand your coffee palate or want to experience Hawaii beyond Kona coffee, these uncommon varietals are a perfect place to start.
Brewing a cup of rare Hawaiian coffee is like holding a piece of paradise in your hands. Take a sip, and you’ll taste the Aloha spirit in every drop.
