This coffee’s roasted in our espresso style — but that doesn’t mean you need to brew it as espresso. You can make it however you like — espresso, filter, moka pot, AeroPress or whatever you enjoy. We roast it a touch darker than we would a filter roast to caramelise the sugars and bring out smooth chocolatey and nutty flavours that cut beautifully through milk.

When you add milk the natural sweetness, fat and proteins tend to soften acidity and highlight caramelised flavours. That’s why lighter filter roasts can sometimes taste a bit sharp or sour with milk — they’re simply not built for it. Espresso roasts being more developed balance this out. The deeper caramelisation creates toffee and cocoa notes that blend harmoniously with milk’s creaminess while a hint of gentle bitterness adds that satisfying ‘coffee punch’ in your flat white or cappuccino.

If you prefer your coffee black this roast will still give you a full-bodied rich cup with plenty of depth and sweetness. For a lighter fruitier experience you might enjoy exploring our filter range instead.

Typica is one of the oldest and most genetically pure Arabica varietals, originating in Ethiopia and spreading globally via Yemen. It forms the genetic backbone of many modern varieties. Known for its balanced cup, it offers a clean sweetness, medium body, and mild acidity. However, it’s highly susceptible to disease and has low yield, which limits its commercial viability in large-scale farming.

A natural mutation of Typica discovered on Bourbon Island (now Réunion), Bourbon is prized for its complex acidity, caramel sweetness, and rich body. It has slightly higher yields than Typica but remains disease-prone. It’s widely cultivated in Latin America and has produced several important offspring varietals like Caturra and Mundo Novo.

In the washed process, coffee cherries are depulped to remove the skin and pulp, then fermented to eliminate the mucilage before thorough washing. This method produces a clean, bright cup with pronounced acidity and clarity, highlighting the coffee’s intrinsic flavors. It’s widely used in regions with ample water resources, such as Colombia and East Africa.

Coffee cultivation relies on diverse soil types that shape plant health, growth, and flavor profiles. Volcanic soils (Andosols) are prized for their sandy, loose texture, enabling deep root penetration and rapid growth, while rich minerals like phosphorus and potassium enhance water retention and reduce erosion. This leads to vibrant, complex cups with clean acidity, as in Ethiopian or Guatemalan coffees. Volcanic ash offers superior drainage and nutrients for bright, nuanced flavors, and black/basaltic soils, seen in Kona, Hawaii, yield fertile, mineral-rich grounds for balanced, floral notes.

Other soils provide unique advantages, often blended for optimal results. Clay retains moisture well, supporting hydration in dry areas and earthy flavors when drained to avoid root issues. Loamy soils balance sand, silt, and clay for excellent fertility and drainage, fostering healthy roots and smooth, sweet cups—commonly paired with volcanic ash, as in "Soil Characteristics: Volcanic Ash, Clay Loam." Sandy soils drain quickly but need extra nutrients to prevent drought, producing lighter, crisp coffees.

Laterite, iron-rich tropical soils, require management for their nutrient gaps but yield bold, spicy profiles. By selecting or combining these—from mineral-packed volcanic types to versatile loamy blends—growers minimize erosion, boost plant vigor, and craft distinctive terroir-driven flavors.

This coffee is stored in standard warehousing palletised under ambient conditions. Usually these coffees are in GrainPro bags to keep out moisture and protect beans. Suited for high-volume blends and economical Single Origins, frequent rotation ensures freshness.

This is a more accurate reflection of the actual roast colour than external as it's measured after grinding. Internal Agtron reveals how far into the bean the roast has penetrated. Our filter roasts often score over 100, preserving acidity, florals, and the unique vibrant characteristics of each origin and process. Please bear in mind that grind coarseness can affect the internal colour readings, so it is impossible to compare from roaster to roaster using this colour reading.

This refers to the surface colour of the whole roasted bean, but it's not always a reliable indicator of roast level. Some of our most vibrant and lightly roasted coffees, like our Ecuadorian Sidra, may appear medium-dark (Agtron 50–60) due to their surface colour, yet are in fact light roasts with minimal development time. Surface colour can be affected by the original green colour, bean type, density, and moisture — so don't judge a bean by its exterior.

The Agtron spread is the difference between the colour of whole beans and ground coffee, showing how deeply the coffee is developed. A spread of 0–10 usually indicates very dark, oily roasts typical of Italian-style, which we don't offer at our Roastery. Spreads between 11–20 and 21–30 represent the roast levels you'll find in our espresso coffees, balancing sweetness, acidity, and body. Spreads above 30 make up most of our filter coffee range, featuring very light, bright roasts that highlight fruity, floral, and complex flavours. Within this, spreads from 31–40 offer clarity and vibrancy, while spreads of 40–50 showcase ultra-light roasts with delicate acidity and nuanced character.

The ROEST P3000 is a compact powerhouse that redefines what’s possible in small-batch production roasting. With the ability to roast 1–3 kg batches in under 7 minutes and crank out over 25 kg per hour, it delivers serious output without demanding a full-time operator. Automation handles everything from preheating to cooldown, with between-batch protocols ensuring consistent conditions roast after roast. Its slim footprint and lightweight build make it perfect for roasteries where space is tight but precision and efficiency are non-negotiable.

What truly sets the P3000 apart is its unmatched control and data richness. It features more than 18 sensors—bean, exhaust, drum, humidity, pressure, and even a first-crack microphone—paired with PID-controlled airflow, drum speed, and temperature. A built-in bean camera offers live visual feedback, eliminating the need for a trier and paving the way for future AI enhancements. Whether you’re dialing in new coffees or replicating profiles at scale, the P3000 brings the lab-level accuracy of the ROEST sample roaster into full production—effortlessly and repeatably.
