How the lineup works
Most of what we taste doesn't make it.
We cup about ten lots for every one we buy, so what's on the shelf is what survived. New here? Our brew guides walk you through it.
Private bookings
We'll bring the bar.
Birthdays, office mornings, weddings, markets. We roll in with the cart, make the drinks, and clean up after, with the same coffee we roast for the shelf.
Three quick steps and you'll see a ballpark the moment you send. No waiting days for a number.

The craft
A roast, stage by stage.
Our logo is a roast curve — bean temperature over time. Here's what actually happens in the ~10–12 minutes from green bean to coffee, and how the bean changes color along the way.
Charge
0:00 · ~200 °C drumRoom-temperature beans hit the hot drum. The probe reads high, then dives as everything equalizes. The clock starts here.
Turning point
~1:15 · ~90 °CThe lowest point — beans and drum reach the same temperature, then start climbing together. A consistent turning point means a repeatable roast.
Drying & Maillard
~5:00 · 150–170 °CMoisture bakes off, then the Maillard reaction takes over — amino acids and sugars browning into hundreds of aromatic compounds. This long climb is where most of the flavor is built.
First crack
~9:00 · 196–205 °CThe beans audibly crack as steam escapes. This is the gateway: green beans become coffee. Stop just after for bright and light; carry on for bold and dark. It's the moment the craft actually lives in — so it's where we put the bean.
Development
drop ~11:00 · 205–210 °CThe short stretch after first crack where acidity rounds into sweetness. Too short tastes grassy; too long flattens out. Then you drop the batch — a full filter roast runs about 10–12 minutes.

From the Lab
Coffee, learned out loud.
Origin, processing, roasting, brewing, sensory: what we're reading, testing, and learning.
Sensory
What Gives Coffee Its Body
When an espresso coats the mouth and a pour-over rinses through, that difference isn't strength — it's body. Three things build it: dissolved polysaccharides that raise viscosity, melanoidins that form during roasting and add molecular weight, and oils that paper filters trap but metal mesh and pressure let through. Understanding the three lets you explain almost any mouthfeel difference between brew methods, roast levels, and grind sizes.

Roasting
How Strecker Degradation Builds Coffee's Aroma
Green coffee beans contain free amino acids that smell like nothing useful. At around 190°C those amino acids hit reactive compounds from the Maillard reaction and break apart — converting into Strecker aldehydes, the highly aromatic molecules responsible for coffee's malt, honey, chocolate, and floral notes. Here's the specific reaction chain, and why the bean's protein chemistry partly predicts the aromatic outcome before the roaster does anything.

Processing
The Sticky Middle: How Honey Process Rewrites a Bean
Between washed and natural lies a third approach — honey process, where the cherry is depulped but the mucilage layer is left on during drying. That gelatinous coating, running 15–22 Brix in sugar concentration, becomes a fermentation substrate. The amount retained determines the outcome: white honey stays close to washed; black honey pushes toward natural. Here's the chemistry driving the difference.
