ARDI™ Consistency Case Study

What makes a natural process coffee stable since 2009? Not magic—operational discipline. ARDI proves that naturals don't have to be volatile if you control the right variables.

The Challenge

Natural coffees are volatile by nature

Most naturals vary year to year. Drying conditions change. Fermentation is hard to control. Storage affects flavor. Roasters learn to expect inconsistency from natural process coffees.

Drying variance: Weather changes everything. Too fast and you get grassy notes. Too slow and you risk mold or over-fermentation.
Cherry quality: Underripe or overripe cherry shows up fast in naturals. Defects don't hide.
Storage sensitivity: Fruit sugars are less stable. Naturals can fade or drift if stored warm.

What most roasters accept

"Naturals are different every year." "You have to adjust your roast profile each crop." "It's part of the charm."

We disagree. Consistency is possible. It just requires discipline.

"This is the only coffee that's been consistent since 2009."

The Name

Named after an early hominin discovery

ARDI takes its name from Ardipithecus ramidus—a 4.4-million-year-old hominin fossil discovered in Ethiopia's Afar region. One of the earliest known human ancestors, the discovery reshaped how we understand human evolution.

We chose the name because ARDI represents something foundational: what natural process coffee can be when done right. A reference point. A standard.

The System

How ARDI consistency happens

01

Same producer network

20+ year relationships with the same washing stations and farmers in Guji. They know the ARDI standard. We don't switch sources chasing price.

02

Cup at origin

Sam cups every potential ARDI lot at origin before we commit. If it's not the ARDI cup—that fruit-forward, clean, balanced profile—we leave it. No exceptions.

03

Spec requirements

Moisture 10–12%. Water activity 0.50–0.55. These aren't suggestions—they're requirements. Lots that don't meet spec don't become ARDI.

04

Re-cup on arrival

Every lot gets cupped again in Baltimore. If the arrival sample doesn't match the origin sample, we investigate. Transit damage happens—but we catch it.

05

Climate-controlled storage

Naturals need consistent temperature and humidity. Our warehouse maintains optimal conditions. The ARDI you buy in October cups like the ARDI from June.

06

Volume commitment

We buy enough ARDI to serve our customers year-round. This gives us leverage with producers and ensures consistent supply across harvest cycles.

The Cup

What stays the same, year after year

Strawberry Peach Blueberry Florals Cocoa structure

Fruit-forward without ferment. Sweetness without booze. The balance that makes roasters reorder year after year.

Roaster feedback

"We've been buying ARDI for 8 years. Same roast profile works every time."
"The only natural we trust for espresso blend."
"Our customers know the flavor. Consistency matters."

Comparison
