Fresh Roast SR800 Specifications — Full Tech Sheet (2026)

The SR800 is a fluid-bed (hot air) home coffee roaster manufactured by Home Roasting Supplies. It is the larger sibling of the Fresh Roast SR540, with roughly twice the batch capacity, a stronger heater, and a heavier-duty fan. Below are the verified manufacturer specifications:

A practical specification note: the SR800 is voltage sensitive. Home Roasting Supplies and the Sweet Maria’s tip sheet are explicit about this — the roaster is engineered for a true 120–122V at the wall. Even modest sag from a long extension cord or a shared circuit can delay first crack and reduce maximum chamber temperature. Plug the SR800 directly into a wall outlet on its own circuit if possible.

What’s in the Box

Out of the box, the Fresh Roast SR800 ships with everything you need to roast your first batch — minus the green beans themselves. The 1-year warranty covers the base unit; the chaff collector, top cap, and basket carry a 6-month warranty.

• SR800 base unit with built-in high-output heater, fan, and electronic control panel
• Glass roasting chamber with stainless mesh basket
• Top assembly with integrated chaff collector and lid
• Multi-function control knob (toggles between heat, fan, and timer with a single push)
• Owner’s manual and quick-start instructions
• Power cord (120V North America only — does not ship outside North America)

What is not in the box: green coffee, a scale for repeatable batch weighing, a heat-safe cooling setup if you want extra airflow after the built-in cool cycle, and optional accessories such as the glass extension tube or a temperature probe. Add accessories only when they solve a specific workflow need; they are not prerequisites for learning the stock SR800.

Build Quality and Footprint

At 14 inches tall by 8.5 inches square, the SR800 is roughly the footprint of a kitchen blender — not the smallest home roaster on the market, but small enough to live on a counter or fit easily under a stove range hood for ventilation. The base is a hard plastic shell that houses the heating element, the fan, and the control board; the upper assembly is borosilicate glass with a stainless steel mesh basket and a top-mounted chaff collector with a fine wire mesh insert.

The build philosophy is “simple and serviceable rather than premium”. Replacement glass chambers, mesh baskets, chaff collectors, top caps, and even motors are sold individually through Home Roasting Supplies and Sweet Maria’s, and the unit is designed to be field-serviceable with basic tools. That trade-off is part of why the SR800 has remained relevant for so long: when something wears out — and a glass chamber will eventually crack if dropped — you replace the part for $20–$80, not the whole machine.

• Materials: hard plastic base, borosilicate glass chamber, stainless steel mesh basket, silicone gaskets
• Footprint: 14″H × 8.5″W × 8.5″D — fits under most stove range hoods
• Weight: approximately 8–10 lbs — counter-stable but easy to move
• Visibility: full glass chamber — colour change is the most reliable roast indicator
• Serviceability: almost every part is replaceable through Home Roasting Supplies and Sweet Maria’s

How the Fresh Roast SR800 9×9 Fan and Heat Controls Work

The SR800’s defining feature is its independent 9-level heat and 9-level fan control. Every fluid-bed roaster has to balance two variables: how much heat the chamber generates and how aggressively the fan moves air through the bean mass. On cheaper popcorn-popper-style roasters those variables are mechanically coupled — turn up the heat and the fan also speeds up. On the SR800 they are independent. You can run Heat 9 with Fan 4, or Heat 5 with Fan 9, or any combination in between. That independence is what enables real profile work.

Operationally, the SR800 has one large multi-function knob and a digital display. Push the knob to toggle between heat, fan, and timer; rotate to adjust the active parameter. All three can be changed at any moment during the roast — useful when first crack arrives early and you need to drop the fan or pull heat in the same second.

The Sweet Maria’s SR800 tip sheet is unambiguous about how to use these controls: keep heat high (7–9) for nearly the entire roast and use the fan as the master profile control. The reason is that on the SR800, dropping the fan does two things simultaneously — it slows bean motion and raises chamber temperature, because there is less cool incoming airflow. So as the roast progresses and the beans get lighter (and need less air to stay aloft), you step the fan down level by level, which both keeps the bean motion correct and pushes more heat into the bean mass right when you need it for first crack and development.

How to Roast Coffee on the Fresh Roast SR800: Your First Roast

The single most common reason first-time SR800 owners get an inconsistent first roast is using too small a batch. The chamber is engineered for 200–240g of green beans — under that you get violent bean motion, beans pinging into the chaff collector, and a roast that flies through development before you can react. Start with a forgiving washed Latin American — Colombia, Brazil, Guatemala — at about 215g. Avoid Ethiopia naturals or Yemeni for your first three roasts; they are wonderful coffees but unforgiving roasters.

1. Set up: place the SR800 directly on a wall outlet (no extension cord), near a window or under a vent hood. Have a metal colander, a digital scale, a notepad, and a stopwatch ready.
2. Weigh: about 215g of washed-process green coffee beans. Cleaner-roasting beans for first-time users include Colombia Huila, Brazil Cerrado, and Guatemala Antigua.
3. Reset defaults: follow the manual reset procedure to set defaults to Fan 9, Heat 9, Timer 20:00.
4. Charge and start: tip the green beans into the chamber, replace the chaff collector top, push start. The fan should ramp instantly, the heater follows within seconds, and the green beans should be in steady visible motion.
5. Drying phase 0:00–4:00: Fan 9, Heat 9 for the first 1:30. At 1:30, drop fan to 8. At 3:00, drop fan to 7. The beans turn from green to yellow.
6. Maillard phase 4:00–6:30: hold Fan 7, Heat 9. Beans go from yellow to tan to light brown. You should start to smell warm bread, then caramel.
7. First crack window 6:30–8:30: drop fan to 6 at the first hint of crackling. First crack is a popcorn-like popping that builds over 90–120 seconds. Note the time first crack starts — that’s the most useful data point you will collect today.
8. Development phase: for a forgiving City+ roast, hold Fan 6, Heat 9 and ride 60–90 seconds past the start of first crack — then hit cool. For a Full City, ride 2–3 minutes past first crack, dropping fan to 5 if needed to drive temperature.
9. Cool: press the cool button. The heater shuts off and the fan continues at high speed. After 3–5 minutes, dump beans into a metal colander and stir gently to finish off-gassing.
10. Rest and brew: rest 24 hours minimum, 3–5 days for filter coffee, 7–14 days for espresso. Brew, taste, write notes, change one variable for the next roast.

Five Fresh Roast SR800 Roast Profiles: City Through Dark

The five profiles below are research-based starting points synthesized from Sweet Maria’s published Fresh Roast guidance and the SR800’s documented controls. They are not CoffeeGearHub test results. Bean density, processing, line voltage, ambient temperature, batch size, and the individual machine can shift timing substantially, so use color, aroma, bean movement, and first-crack cues rather than treating the clock as a guarantee.

Profile 1 — Filter Sweet Spot (Light-Medium, City)

Best for: pour-over and AeroPress brewing of bright single-origin coffees — Ethiopia, Kenya, Colombia naturals.

Profile 2 — Balanced All-Purpose (City+)

Best for: the daily driver — works for filter, AeroPress, and milk drinks. The most forgiving profile on the SR800.

Profile 3 — Espresso-Friendly (Full City)

Best for: espresso and milk drinks. Sugars develop, body builds, surface is matte just before second crack.

Profile 4 — Dark Italian-Style (Full City+)

Best for: classic Italian-style espresso, French press, milk drinks where you want oils on the bean surface and a chocolatey body. Air roasters can push past second crack — go gently.

Profile 5 — Slow Development (Sweetness-Focused)

Best for: Brazil, Honduras, Guatemala — coffees where you want maximum sweetness and a longer Maillard window. A slightly extended drying and Maillard phase costs about a minute and yields noticeably sweeter cups.

Origin-Specific Recipes — Ethiopia, Colombia, Brazil, Sumatra

Bean density, processing method, and screen size all change how a coffee responds to the SR800. The four origin recipes below are starting points — refine them by varying the development time first, then the Maillard length.

Ethiopia (Yirgacheffe / Sidama, washed)

Smaller, denser beans that move easily in the SR800 chamber. Capable of brilliant floral and citrus expression at light roast, but goes from City to Full City fast — watch closely.

• Batch: 220–230g — slightly smaller for naturals (210g)
• Use: Profile 1 (Filter Sweet Spot) or Profile 2 (City+)
• Watch for: first crack arrives slightly later (~8:00–8:30) due to bean density
• Drop at: end of first crack for jasmine and bergamot, or 60s into development for blueberry-forward naturals

Colombia (Huila / Nariño, washed)

The most forgiving origin on the SR800 — large screen size, even moisture, broad roast window. Use this for your first three roasts.

• Batch: 230–240g
• Use: Profile 2 (City+) or Profile 3 (Full City) for milk drinks
• Watch for: first crack at 7:30–8:30; clear, sustained popping
• Drop at: 90 seconds into development for caramel-cocoa balance

Brazil (Cerrado / Sul de Minas, natural / pulped natural)

Lower-altitude, lower-density beans that develop sweetness with longer Maillard. Often run in espresso blends — push to Full City for chocolatey body.

• Batch: 220–230g (naturals chaff more — keep below 230g)
• Use: Profile 5 (Slow Development) or Profile 3 (Full City)
• Watch for: first crack at 7:00–8:00; quieter than washed origins
• Drop at: 90s past first crack (City+ for filter) or just before second crack (Full City for espresso)

Sumatra (Mandheling, wet-hulled)

Wet-hulled processing produces irregular bean shapes and uneven moisture — Sumatran greens look like nothing else on the bench. Best at darker roasts where the syrupy, herbal character emerges.

• Batch: 230g
• Use: Profile 3 (Full City) or Profile 4 (Full City+) — Sumatra rarely shines lighter than Full City
• Watch for: uneven colour development through first crack — normal for wet-hulled
• Drop at: just before or at the very start of second crack for cedar, dark chocolate, and herbal notes

Fresh Roast SR800 Upgrades: Extension Tube and Thermocouple Mod

The SR800 has a mature accessory and owner-support ecosystem. Two commonly discussed upgrades are the glass extension tube and an external temperature probe. Neither is required for basic roasting: the extension tube primarily changes airflow and bean movement, while a probe can add another temperature data source for logging and repeatability.

Upgrade 1 — Glass Extension Tube

The Fresh Roast glass extension tube is designed to improve bean movement and can help users dealing with inadequate line voltage. Sweet Maria’s explicitly states that the SR800 extension tube does not increase the machine’s rated batch size: the SR800 remains an 8 oz roaster with or without the tube. Exceeding the specified quantity can overfill the chaff basket and increase fire risk.

Upgrade 2 — Type K Bean-Probe Thermocouple

The SR800’s onboard temperature display reads chamber temperature under the bean mass — useful but not the same as bean temperature. Adding a Type K bean-probe thermocouple connected to a handheld thermometer (Mastech MS6514 is the community favourite) or a Phidgets interface to Artisan logging software gives you actual bean temperature data — the variable that drives roast development. The mod is straightforward: drill a small hole in the chaff collector lid, insert the probe, secure with a fitting, and connect the leads to your thermometer or Phidgets.

• Probe length: 110–150mm for stock chamber, 250–300mm for extension tube
• Probe diameter: 3.2mm for Phidgets fittings, 4mm for Mastech setups
• Thermometer options: Mastech MS6514 (handheld, simple), Phidgets TMP1101 (USB, integrates with Artisan)
• Tools needed: drill with appropriate bit, mounting fitting/nut, wire stripper, mini screwdriver for plug assembly
• Add when: you want repeatable roasts, are running data-driven profile work, or are training someone else on the machine

Fresh Roast SR800 Troubleshooting: The Top 7 Issues, Fixed

Fresh Roast SR800 vs SR540 vs Behmor vs Aillio Bullet: Head-to-Head Comparison

SR540 vs SR800: the same control logic, the same form factor, but twice the capacity, more heater wattage, and a heavier-duty fan in the SR800. Choose the SR540 only if budget is tight or you brew 1–2 cups per day; otherwise the SR800 is worth the upgrade. Read the full home coffee roasting comparison for both.

SR800 vs Behmor 2000AB Plus: the Behmor wins on capacity and indoor-friendliness — its patented smoke suppression makes it the kitchen-friendly choice for households roasting one pound at a time. The SR800 wins on speed, control granularity, and aftermarket. Many home roasters eventually own one of each. See our full Behmor 2000AB Plus review.

SR800 vs Aillio Bullet R1: the Bullet is a different category — a 1 kg induction drum roaster with continuous PID control and pro-grade thermal mass, priced at roughly four to five times the SR800. The right comparison is “starter roaster vs forever roaster”. The SR800 is the right machine for years one through three of home roasting; the Bullet is what you upgrade to when capacity or repeatability becomes the limiting factor.

Recommended SR800 Accessories

⚖️ Essential — Greater Goods Digital Coffee Scale

A 0.1g-resolution digital scale is non-negotiable for repeatable SR800 roasting. Even 10g of variation between batches shifts your first-crack time by 30+ seconds. Use the same scale for green-bean weight in and roasted-bean weight out — the percentage weight loss is the single most useful indicator of roast level (12–14% loss for City, 14–16% for City+, 16–18% for Full City, 18–20% for Full City+).

☕ Recommended — Airscape Classic Coffee Canister

Freshly roasted coffee off-gasses CO₂ for 24–72 hours — sealing it in a standard airtight container causes pressure buildup and off-flavours. A canister with a one-way degassing valve (Airscape, Fellow Atmos, or Friis) lets CO₂ escape while blocking oxygen. The 250g size is a perfect match for the SR800’s batch output. Rest City+ in the canister for 3–5 days before grinding for filter; rest espresso roasts 7–14 days.
