West-side cup · not a 10% blend
Island Coffee Bar
Island Coffee Bar is the Hawaii coffee guide: real Kona, a better brew, no 10% blend.
The gap
You had the cup on-island.
Then you got home, bought something labeled Kona, and wondered why it tasted like the grocery aisle. This site is for that gap. We help you tell a real bag from a 10% blend, brew it like it deserves, and skip the names that are not this site.
If you want a bag, start with 100% Kona Coffee from a named estate. If you want to know why those words matter, start here.
The west-side belt
Kona is a district and a cup, not a roast style.
How to shop
Three jobs
01
Read the identity line.
Look for the words “100% Kona Coffee.” Until 30 June 2027 a blend can legally wear a Hawaiʻi geographic name with as little as 10% of that origin in the bag (HRS §486-120.6 / Act 198). From 1 July 2027 the floor rises to 51% if that name is used. Blend percentage already has to be disclosed. The clean move is still those four tokens.
02
Pick a named estate when you want the west-side cup.
Genuine 100% Kona on farm sites commonly sits in the $30–$60+/lb range people see when they shop direct. A cheap “Kona” bag is usually a blend. That range is a smell test, not a certified floor.
03
Brew it without wrecking it.
Burr, not blade. A widely used start is 1:16 at about 200°F (93°C). Method does not fix a 10% blend.
If you already have a bag in your hand, skip to How to read a Kona bag. If you are still shopping the word, read in the order below.

05
Pour-over vs drip for Kona
How method changes a mild sweet cup; start 1:16 / ~200°F.
06
The grinder that doesn’t wreck the bag
Burr vs blade; kettle and scale are optional.
07
Coffee club or just a bag
One bag first; a club is freshness plus lock-in.
08
Farm-direct vs the supermarket bag
Roast date, who roasted it, supermarket blend risk.
09
Roast date vs best by
Roast date is when the coffee became coffee you can brew. Best-by is a warehouse horizon.
10
What elevation on a Kona bag means
Elevation on a Kona bag is a west-side farm altitude note, not a roast style and not proof the bag is 100% Kona.
11
What peaberry actually means
Peaberry is a bean shape. Hawaii calls it Type II: one oval seed in the cherry, not two flat-sided beans.
12
Whole bean vs ground
Buy whole bean and grind it right before you brew. That is the short answer once you are holding a real bag of 100% Kona Coffee.
13
How to store an opened bag of Kona
Keep an opened bag of 100% Kona whole bean, sealed tight, and somewhere cool and dark. Skip the refrigerator.
14
How to brew Kona in a French press
French press is one of the easier ways to drink a new bag of 100% Kona. You grind coarse, pour hot water, wait, and press.
15
How to make Kona cold brew
Cold brew is coffee that never meets hot water. You grind coarse, stir the grounds into cold water, let the jar sit in the fridge, then strain.
16
Light, medium and dark roast
Light, medium and dark on a 100% Kona bag describe how far the beans were roasted.
17
What "estate" means on a Kona bag
"Estate" and "single estate" on a 100% Kona bag point to the farm the coffee came from.
Next: What Kona actually means — Kona is a west-side district and a cup, not a roast style.
