Frequently Asked Questions

You can buy the Aillio Bullet directly from Aillio's online store or through an authorized local retailer or distributor.

Direct webshop: Ships worldwide, pay by credit card, Google Pay, or Shop Pay.

Local dealers: Native-language support and more regional payment flexibility.

Direct orders generally ship by air within days from fulfillment warehouses. Live lead times display at checkout. For distributor or retailer orders, lead time depends on regional stock, so check with them directly.

Aillio ships globally. Live shipping quotes are calculated at checkout based on model, voltage, and destination address. If you do not see a shipping option, contact [email protected]

Import costs vary widely throughout the globe, and run roughly 10–30% in the US and 20%+ in the EU. LATAM customs calculate duty on the CIF value (product + freight combined), not just the machine price. Shipments are declared as coffee roasters under HS code 8516. Once freight, customs, and broker fees are added, importing direct can cost as much as buying locally.

You cannot pay in installments through Aillio's webshop, but some local distributors offer regional financing or more flexible payment terms.

Order cancellations are almost always a bank fraud block on a high-value international charge, or a data-entry error at checkout. Contact your bank to authorize the transaction, or email [email protected] if the issue continues.

No extra parts are needed to start roasting — every Aillio Bullet ships complete.

Every new Aillio Bullet includes a 2-year warranty on parts and labor, with 1–2 additional years available as an extended warranty at checkout. Improper ventilation, missed maintenance, or hardware modification can void the warranty. Distributor/retailer purchases go through the dealer for claims; direct purchases go through [email protected].

The Bullet is ideal for home roasters looking for greater capacity and control, for roasting extremely high-quality/competition coffees, for micro-roasteries, for cafés, for coffee research labs, and for larger roasteries using it as a sample roaster. It's an extremely versatile machine in this regard.

You can read all about how real people use the Bullet on our Good Machines for Good People site.

Yes — many businesses have been built with Aillio roasters. Each of the models fits a different scale of operation. R2 Pro: Built for high-volume environments where maximizing throughput and optimizing workflows matters most.

R2: More power than the R1 and easier maintenance for flexible micro-roastery workflows.

R1 (legacy, unavailable for purchase): Suits micro-roasteries and small cafés, but not optimized for higher volumes.

The Bullet R2 Pro is the 1.2kg commercial model with the most power, the R2 is the current standard 1kg model, and the Bullet R1 (and Bullet R1 v2) is Aillio's retired legacy model that is no longer available for purchase.

The R2 series picks up where the R1 left off and features a number of new, innovative features:

• Power Headroom: The R2 (+150 watts) and R2 Pro (+750 watts) are substantially more powerful than the R1, allowing for more headroom for maximum batch sizes (R2: 1kg, R2 Pro 1.2kg). The R2 Pro is so powerful that it can be loaded with a full 1.2kg batch and still reach First Crack in under 7 minutes.
• FlowSense & Smart Maintenance: Both the R2 and R2 Pro feature FlowSense technology, which measures airflow dynamically and adjusts fan speed to maintain stability in different environmental conditions. They also include QuickClean maintenance access and a Filter Clean Alert, which automatically detects when your chaff filter needs cleaning.
• Bean Guard: Both R2 and R2 Pro roasters ship with an integrated Bean Guard to minimize bean spillage at drop, addressing one of the main complaints of the R1 unit.
• Advanced Cooling: The R2 Pro ships with both the Standard Cooling Tray (active, detachable) and the Pro Cooling Tray, which is designed to quickly cool 1.2kg batches and is fitted with automated silicone stirrers and a bag spout for easy bagging, streamlining professional workflows.

No — the Aillio Bullet R1 is no longer available for new purchase, succeeded by the R2 and R2 Pro. Aillio continues to fully support existing R1 owners with spare parts, customer service, and RoasTime/Roast.World compatibility. R1 owners wanting a better roasting experience with more power, FlowSense, and QuickClean can upgrade to the R2 or R2 Pro.

Bullet R2 Pro: 200V-240V ONLY (12A draw / 2300W peak). It cannot run on standard North American 110V household outlets.

Bullet R2: Available in 110V-120V (15A draw) or 200V-240V (8A draw) versions (1700W peak).

Plugs: Depending on location the Bullet ships with standard plugs for AU/EU/KR/US/JP/UK/AR/CH/BZ. The R2 Pro and R2 (200+V) models ship to the US with two plugs: NEMA L6-20P and NEMA 6-20P. You will require a compatible power line and receptacle.

There is no limit on how much you can roast per day or per month, but please remember to follow proper maintenance procedures as outlined in the manual.

Because they are even more powerful than the original Bullet R1 roasters, many users push their R2 (1kg) and R2 Pro (1.2kg) machines to their maximum capacity. You probably won't need to limit batch sizes to hit your "sweet spot."

For your reference:

Bullet R2 Pro: Backed by a 2300W commercial-grade induction system, a full 1.2kg batch can be brought to first crack in under 7 minutes.

Bullet R2: An optimized induction power delivery system brings a a full 1kg batch to first crack in roughly 7-9 minutes.

Bullet R1 (legacy): A 1kg batch typically reaches first crack in 9-12 minutes depending on your voltage and ambient environment.

Yes, all Aillio Bullet models support back-to-back roasting mode, allowing you to start a new roast while cooling the previous batch.

Check the manual for more details on back-to-back roasting.

The Aillio Bullet has no built-in venting solution, so what you need depends on your batch size and roast level.

Light Roasts, Small Batches: Roasting under an oven hood is often enough.

Large batches or Dark Roasts: These need outdoor ducting via an extraction hood or flexible ducting. Leave a small air gap rather than hard-sealing an inline fan to the exhaust port, so you don't create vacuum pressure that disrupts airflow and FlowSense readings.

Air Cleaner Alternative: A standalone air cleaner works well as an alternative to venting for indoor roasting — Aillio used one in our own office.

The manual includes detailed guidance on setting up proper venting, including what to do (and what not to do). You can also view our Starter Guide video for information about: Assembling the Bullet, Setup and Venting, RoasTime Software, IBTS and Preheat, Seasoning the Drum, First Roast and Basic Cleaning.

Yes, the Aillio Bullet requires maintenance to run properly. Regular cleaning prevents oil buildup, airflow restriction, and errors; how often you need to clean depends on how much and how dark you roast. QuickClean speeds maintenance up on the R2 Pro/R2.

The most common tasks are emptying the chaff collector and filter screen every few kilos, as well as wiping the IBTS lens periodically with an alcohol swab.

The frequency and extent of additional maintenance depends on how often and how dark you roast. Detailed maintenance recommendations and cleaning schedules are available within our Technical Support Docs.

Direct induction heating transfers energy directly into the solid carbon-steel drum, turning the drum itself into the heat source with zero open flames or combustion gases found in gas roasters, without utilizing slow, resistive coils found in other electric roasters. It's also the reason we are able to pack so much power into a roaster with such a small footprint.

• Instant Thermal Control: Power adjustments transfer directly into the drum without the thermal lag present in other electric roasters.
• Zero Direct Emissions: Operates cleanly on electricity, eliminating gas line installations and reducing indoor permitting hurdles.
• Repeatable Results: Removes environmental ambient gas pressure fluctuations for reliable profile playback.

The IBTS (Infrared Bean Temperature Sensor) reads real-time infrared surface radiation from the beans or drum, rather than physical contact, so readings stay consistent regardless of batch size. A traditional probe reads air temperature when preheating, and its accuracy during a roast depends on the amount of beans in the drum — a 350g batch can register First Crack dramatically low compared to a full 1,000g batch. By using IBTS, you enjoy accurate preheat settings and batch-size immunity, making it easier to dial in a profile on a small sample batch and scale it up reliably.

FlowSense is the Bullet R2 and R2 Pro's airflow system that tracks internal differential air pressure and automatically adjusts fan speed to counter clogs, wind, or exhaust fluctuations. It's paired with a barometric sensor that corrects for altitude and weather-driven pressure shifts.

QuickClean is a structural design overhaul for the R2 generation. The front plate, impeller fan, and air-pathway housings can be disassembled for deep cleaning in seconds without needing to pull apart the primary structural chassis of the roaster like the classic R1 required.

The Aillio Bullet R2 Series automatically detects and alerts you when your chaff filter needs cleaning by measuring changes in airflow.

Yes — RoasTime and Roast.World let you utilize "Overlays" or "Roast Recipes" that automate power, fan, and drum speed based on time or IBTS temperature targets. You still need to be physically present while these automated modes are running.

The Aillio Bullet runs exclusively on Aillio's free RoasTime software (Mac, Windows, Linux) and syncs natively to the Roast.World cloud community for storing, analyzing, and sharing profiles.

• Real-Time Data & IBTS Overlay: Charts bean temp, Rate of Rise, power steps, fan steps, and drum speed simultaneously without sensor lag.
• Recipe Playback & Automation: Save a profile as a "Roast Recipe" and let RoasTime automate power/fan adjustments based on IBTS triggers.
• Cross-Platform & USB-C: Runs natively on macOS, Windows, and Linux.

RoasTime is required to register your Bullet and unlock extended warranty coverage, and it's how firmware updates and diagnostic data reach Aillio's support team.

RoasTime allows you to build or download automated Roast Recipes that trigger power, airflow, and drum speed adjustments based on time or IBTS temperature targets—like automatically dropping heat at 185°C IBTS or ramping fan speed before First Crack. Because you can manually override settings at any point and edit saved Roast Recipes after cupping, Roast Recipes provide an exceptionally flexible framework for both repeating production roasts and running precise, hands-free profiling experiments.

RoasTime is the free desktop application (macOS, Windows, Linux) that connects directly to your Bullet via USB-C to log roasts, control hardware settings, and execute automated Roast Recipes. Roast.World is the cloud platform that syncs with RoasTime, acting as a global profile database, green coffee inventory tracker, and community hub. Every roast you log in RoasTime can automatically backup to your private Roast.World account or be shared with the community.

Yes. Roast.World includes built-in green coffee management tools. You can log green coffee purchases (origin, process, moisture content, price), assign inventory to specific roasts, and track remaining stock automatically as you roast. You can also log cupping notes, SCA scores, and flavor profiles directly on completed roast logs to correlate target curves with final cup quality over time.
