The roast is where flavour is unlocked — not created. The origin and process set the ceiling. We try to hit that ceiling every time: building profiles around each coffee's character, not forcing everything into one "house" taste. Here's how it actually works.
Small-batch, profile-driven roasting means every lot gets treated as its own project — different moisture, different density, different flavour goal. Eight steps from green intake to QC cup, and every batch either passes or gets pulled.
Every coffee is different. We build profiles around origin and process — preserving character, not flattening it into a "house" flavour.
From receiving a bag of unroasted green coffee to clearing it for your bag. Steps 5 and 6 are where roast level is defined.
Every lot is logged and checked for moisture, density, and screen size. These physical properties shape how the bean behaves in the drum — a denser bean needs more energy, a wetter bean needs more drying time early. This data goes straight into the profile.
Profiles are designed around origin, process method, and intended use — single origin, blend base, espresso component. Gas and airflow are dialled ahead of the session to target a flavour outcome, not just a colour reading.
Beans hit the pre-heated drum ("charge") and the probe temperature dips as cold beans absorb heat, then climbs. The Turning Point — where temp begins rising again — is our first confirmation the roast is tracking the planned curve.
Sugars brown and hundreds of aromatic compounds form. Rate-of-rise control is critical here — too fast and the outside chars before the inside develops; too slow and beans taste baked and flat. This phase builds structural sweetness and body.
Internal pressure builds until beans audibly crack and visibly expand. This is the start of the development window — the earliest point at which coffee is drinkable. We mark the exact time and temperature of first crack on every single roast.
From first crack to drop: shorter development preserves brightness and origin clarity; longer deepens caramelisation and body. We never push into ashy territory. Development time ratio is tracked as a percentage of total roast time on every batch.
At target colour and temperature, beans drop into the cooling tray and are stirred rapidly. Slow cooling continues the roast beyond the intended endpoint — baked, flat notes are almost always a cooling problem, not a roasting one.
Beans off-gas CO₂ for 18–72 hours before cupping. We blind-taste every roast against the benchmark profile. If sweetness, clarity, body, or finish is off, the roast doesn't ship. No exceptions.
Steps 5 and 6 — first crack and development time — are where roast level is determined. Everything before sets the stage; everything after locks in the result. Two coffees can reach the same colour reading via very different paths and taste completely different from one another.
Roast level is the biggest flavour variable after origin. Light isn't "better" than dark — they're different tools for different preferences and brew methods.

Roast character leads, deep comfort
Every roast is evaluated before it ships. If a batch misses the target profile on the cupping table, it doesn't become your morning coffee. Simple as that.
Roast curves, colour readings, and extraction results are logged per batch and compared against the benchmark profile — not just the last run.
Multiple tasters evaluate sweetness, acidity, body, and finish. Cups are coded — we don't know which batch we're tasting until after scoring is complete.
We test on real home and commercial setups — your Chemex, your espresso machine, your French press — not just ideal lab conditions.
As beans absorb heat, internal water vapour and CO₂ build pressure until cell walls rupture — producing an audible crack around 385–400°F (196–204°C). This is first crack.
It matters because it marks the start of the development window: the earliest point where a roast is drinkable. Light roasts drop shortly after; medium and medium-dark extend further. The timing relative to first crack is one of the most critical decisions in profile design.
Development time is the interval between first crack and when beans are dropped. Often expressed as a development time ratio (DTR) — the percentage of total roast time spent in development.
Shorter development preserves clarity, brightness, and origin character. Longer development deepens caramelisation and builds body. Most specialty roasters work in a DTR of 18–26% depending on the coffee's intended outcome.
Immediately after roasting, beans are saturated with CO₂ that escapes rapidly over the first 24–72 hours. If you brew before adequate degassing, the gas interferes with water contact and extraction, producing a hollow or uneven cup.
For filter brewing, 5–14 days post-roast is optimal. For espresso, 10–21 days often produces better consistency and sweetness. The roast date on the bag is your real freshness guide.
Not meaningfully. Caffeine is heat-stable — roasting doesn't significantly degrade it. The difference in caffeine between a light and dark roast of the same coffee is negligible.
The perception of "stronger" from dark roasts comes from bolder, more intense flavour, not actual caffeine content. If anything, light roasts have marginally more caffeine by weight because the bean hasn't lost as much mass — but the difference is trivial in practice.
Colour-based roasting uses a colorimeter to hit a target Agtron reading — consistent, but it doesn't account for how different coffees develop flavour along the way to that colour.
Profile roasting tracks the full temperature curve — charge temp, turning point, rate-of-rise, first crack timing, DTR, and drop temp — adjusting in real time to match a curve built for that specific coffee. Two coffees can reach the same colour via different paths and taste completely different. Profile roasting controls the path, not just the endpoint.
Sealed, opaque container at room temperature — away from heat, light, and moisture. The fridge introduces condensation. Freezing only helps for long-term storage of unopened, vacuum-sealed bags you won't touch for a month or more.
The biggest single improvement: grind immediately before brewing. Ground coffee loses flavour measurably within hours. A decent burr grinder does more for your cup than any other single upgrade.
