The Roastery

One drum,
twice a week.

Behind the glass at the back of the room sits a 12-kilo drum roaster that has been running since 1989. Every bean we pour or sell passes through it, twenty feet from where you sit.

The Process

Farm to mug in four steps

Most of the work happens before the drum ever turns, and some of it after.

Step 01

Sourcing

We cup samples from our nine partner farms each harvest, pick the lots we love, and agree on a price before the coffee leaves the farm.

Year-round

Step 02

Roasting

Green coffee goes into Big Lou twelve kilos at a time. Each origin has its own profile, tweaked batch by batch and written down by hand.

Tue & Thu, 6–11am

Step 03

Resting

Fresh-roasted coffee is full of CO₂. We rest it in valved bags — three days for filter, a full week for espresso — before it hits the bar.

3–7 days

Step 04

Brewing

The bar dials in espresso every morning and again after lunch, and reports back to the roaster when a batch tastes off.

Dialed twice daily

Our Machine

Meet "Big Lou."

Big Lou is a 1989 cast-iron drum roaster, bought used from a closing roastery in San Antonio and driven up I-35 on a borrowed flatbed.

It has been rebuilt twice, but the drum, the trier and the cooling tray are original. Marcus still logs every batch by hand alongside the software.

1974

A secondhand Probat starts roasting in the corner of the sandwich counter.

1989

Big Lou arrives from San Antonio. The roaster moves to its own room out back.

2004

New burners and a rebuilt motor. Dolores refuses to replace the drum.

2016

Afterburner, digital bean probes and the glass wall facing the booths.

Cupping bowls lined up on the roastery table
Cupping

Every batch gets slurped.

Cupping is how coffee gets judged everywhere, from farm to roaster. It is deliberately simple, so nothing hides behind the brew method.

  1. 1

    Grind & smell — Eight grams of fresh grounds per bowl. We note the dry fragrance first.

  2. 2

    Pour & wait — Hot water straight on top, then four minutes while a crust forms.

  3. 3

    Break the crust — Push through the top with a spoon and lean in — this is where the aroma lands.

  4. 4

    Slurp & score — Loud slurps spray the coffee across the tongue. Each cup is scored for sweetness, acidity, body and finish.

Public cupping every Thursday at 3pm at the communal table. Free, ten seats, first come.
