Kona Coffee Grades Explained: Extra Fancy, Fancy, No. 1, and Peaberry

Not all Kona is the same Kona. Hawaii state law defines a grading system for Kona coffee based on bean size and defect tolerance, and the grade on the bag tells you something concrete about what is inside. Koa Coffee's Estate is No. 1 grade. Their Private Reserve is Extra Fancy. Their Peaberry is a separate designation entirely. Understanding the grading system is the key to buying Kona intelligently instead of just by price.

The Hawaii State Grading System

The Hawaii Department of Agriculture defines coffee grades by two criteria: bean screen size (a measurement of bean diameter) and defect tolerance (how many defective beans are allowable per 300-gram sample). The grades, from highest to lowest, are:

Extra Fancy: The Highest Flat-Bean Grade

Extra Fancy is the strictest grade for standard (flat-sided) Kona beans. A minimum screen size of 19 means only the largest beans from the harvest qualify. A maximum of 10 defects per 300-gram sample means the grading is done carefully and defective beans are removed aggressively. The result is a visually uniform lot with larger beans that roast more evenly because consistent bean size means consistent heat absorption.

Koa Coffee's Private Reserve is their Extra Fancy designation. It is their benchmark everyday Kona: the grade they built their reputation on. Medium-roasted to express the milk chocolate, caramel, and citrus brightness that characterizes Kona coffee at its best. Price range: $42 to $155 depending on quantity.

No. 1: The Accessible Grade

No. 1 is the broad middle tier of Kona production, with minimum screen size 16 and up to 20 defects per 300-gram sample. It represents the bulk of most farms' saleable output. A well-farmed No. 1 lot from a meticulous producer who picks selectively and processes carefully cups nearly as well as that farm's Extra Fancy in many blind cuppings. The grade difference shows most in visual uniformity and slightly more variability in roast development due to mixed bean sizes.

Koa Coffee's Estate is their No. 1 grade product. It is the most accessible starting point for first-time Kona buyers: same characteristic profile as the Private Reserve (milk chocolate, nut, clean sweet finish), slightly more variability in bean size, noticeably lower price. Price range: $46 to $176 depending on quantity.

Peaberry: The Special Classification

Peaberry is not a grade in the same hierarchy as Extra Fancy through Prime. It is a separate classification for a distinct bean type: the single round bean that forms when only one seed develops in a cherry. The full explanation of what causes peaberry and why it matters is in our peaberry coffee guide.

For grade purposes, the key point is that Koa's Peaberry is hand-sorted from the farm's harvest, roasted as a separate product with its own roasting profile suited to the round bean's density and shape, and priced above the Extra Fancy Private Reserve because of its scarcity (5% of harvest) and its award-winning status. It is the crown jewel of the lineup and the appropriate choice for gifting or for tasting Kona at its competitive peak.

Which Grade Should You Buy?

First-time Kona buyer: Koa Estate (No. 1 grade). The most accessible entry point into the lineup. Genuine 100% Kona character at a price that makes sense for trying a new origin.

Everyday Kona buyer: Koa Private Reserve (Extra Fancy). The benchmark product, more consistent roasting due to uniform large bean size, the grade Koa built their reputation on.

Gift buyer: Koa Peaberry. The most distinctive product in the lineup, the award-winner, the item whose story lands when you explain what it is. Worth the premium for gift-giving.

Dark-roast preference: Koa Grande Domaine (Vienna roast, Estate grade beans). The only darker-roasted option in Koa's lineup, for buyers who want bold Kona without the lighter-roast character of the main products.
