SR800 Coffee Roaster – Roast Coffee at Home – Variable Heat and Fan Control – Digital Display – Roasts 6–8 oz (170–226g) Per Batch – Easy to Use – Fast Roast Time

The SR-800 replaces our old roaster, which was a smaller, programmable roaster from the same company. The newer version has two distinct benefits in my opinion. First, the new roaster has twice the capacity (180 grams of green beans vs. 90 grams). This means I’m brewing only two batches a week instead of 3-4. That’s a huge time saver. Second, the SR-800 is operated manually, which means you stand by the roaster and adjust the fan and temperature as required during the roast. This may not sound like an advantage, but our previous roaster (now discontinued) was a pain to program and only stored one roasting profile at a time. Not good if you like to try coffee from around the world, because one roasting profile does not suit all coffees. With a manual roaster, you just put in 180 grams of beans and start the machine. What I discovered with the SR-800 is that there are only a few basic principles to follow for a consistently good roast. Hot air is blown into the glass roasting chamber, which pushes the beans in the center up and the beans on the outside down, and so the first principle is to keep the beans moving this way to ensure they are evenly roasted and none are scorched. You start with a high fan speed to circulate the heavy beans and a medium temp to remove moisture, and then gradually increase to maximum temp during the first two minutes. The second principle is to reduce the fan speed step by step as the beans lose their moisture and become lighter. You only need enough fan speed to push the beans in the center to the top so that the outside beans will sink to the bottom. The beans don’t need to be flying around the chamber. As you lower the fan speed, the temp becomes substantially hotter. My roasts generally peak at 450+ degrees Fahrenheit. The third principle is to finish heating the beans within about 8 minutes. I like the beans to start popping at around 6 minutes, and then become evenly dark and plump in the next two minutes. You finish with the cool setting at the highest fan speed and lowest temp for a total time in the roaster of about 10 minutes. If you roast the beans too long, the flavor will become muted and bland. The above is my recipe for a medium dark roast just short of any oil coming out of the beans. I don’t like oily beans because they are messy and the oils starts to go rancid in a few days. I also don’t care for the acidic taste of very light roasts, but to each his own. You can adjust the time and temp as you please to achieve your ideal roast. It takes a few batches to get the hang of it, but it’s not all that hard if you pay attention to what the beans are doing in the roaster for about 8 minutes. Personally, I like watching the beans roast and tweaking the fan and temp. It’s fun and I love the results. The SR-800 seems to be the ideal starter roaster for 2-3 coffee drinkers in one household. Better machines start at double the price and not everyone can taste the difference.

I can't say enough good things about this roaster and especially the customer service. I bought it over 6 years ago and it acted up after 1 1/2 years, which is beyond the 1 year warranty. They will repair a roaster for $50 (plus your shipping to them, only), but i mentioned that i was disappointed that it broke after 1 1/2 years of moderate (1-2 times per week) use. They fixed it free of charge. Five years later it died so I sent it in, still a $50 flat rate repair charge. It was returned in about a week and it looks and performs like a brand new roaster. I know that the $337 price tag is not cheap, but when you amortize it over its lifetime (even including the repair charge) and compare that to how much you save by not buying high-end roasted coffee, I think it's worth the money.

I am now on my second one of these. They work great. I have been home roasting for years and this one holds the most beans and gives me a solid consistent roast once I figured out my timing and temperatures. My only complaint is in the control button. I change my temp and fan speed during the roasting process and after awhile the numbers jump around and the control button gets very temperamental. Happened with the first one and now is happening with this one making it difficult to set the heat level. May need to buy another one, but seems a bit of a waste when all the other parts work great. I don't remember when I bought the last one, but its usually about 2-3 years, so could be worse.

Easy to use. The only problem is that the top breaks easily and no replacement is found with the company. (Well, it breaks easily if you -me- is not careful when handling it).

Lets talk about the flaws first. When its 60 degrees outside it is a bit underpowered. Instead of 220 grams of coffee I roast at a time, I use about 170 grams. You will have to turn up the heat to full, and turn the fan on the highest setting for the drying process. Your beans must always move. At first the beans do not move much as they have moisture in them in the first phase of the drying process. I stir them without the chaff collector on. I have a fan that blows the chaff away from the chimney on the roaster. I do this out in the back yard so I do not care if it makes a mess i just wash it down with water when I'm done. I always check the bean temps with a infrared temp gun through the top of the glass chimney I do not follow the built in temp meter because its a bit off until way in the roasting process. When the beans start moving on there own, I turn the fan to 8 for a minute, then turn the fan to 7 and still on full heat power. Then the beans will get to 360 degrees for a few minutes, on the mallard phase where the beans develope the Sugars. After about 8 minutes in the beans will get to 390 degrees for finishing. You want to keep the beans for about 3 minutes between 350 and 370 to convert the sugars in the bean. After that its the roasting phase, and the temp will go up to 390 or more by that time. If its hotter outside you can add more beans to 220 grams, and should not have a problem getting bean temp to 420 degrees. You really want to check the bean temperature with a infrared temp gun. Dodn't rely trying to get a temp through the glass when your using the chaff collector through the glass with the infrared temp gun. The Chaff collector needs to be off and then you can lazor right into the top of the glass to the beans. if you want to use the chaff collector then fine, but the real bean temperature is abit off on the roaster concerning bean temp. Otherwise when its warm outside, I just fill up 220 grams and go to town. No problems underpowered on warm days. You will need to turn the power down to 8 or seven, and the fan. Remember 3 or 4 mins drying, 3or 4 minutes between 360 and 370 (not over 380 degrees as this is the mallard phase converting starches to sugars and will stop the mallard or sugar developing phase, your coffee will not taste any sweetness.) And the next phase is the real roasting phase. Please unless you like totally black beans with the oils covering the beans its nasty. I do not ever go over 410 degrees. If you see oils on the beans there way overcooked, and your coffee will taste totally bland without good flavors. Primos Coffee on Amazon is good coffee beans very fresh, not too expensive, and really plump up and they are from a single estate so not every Tom, Dick, and Harry's beans is not mixed together. I like green coffee from Mexico the best so I ordered some from Anthony's There products are high quality also, and organic from Mexico. Do try Single Estate coffee its way better.

Have SR500 which I like quite a bit with glass extension (works good), but wanted to upgrade to SR800 since it roasts 8 ounces of green beans at a time. Roasting 8 OZ of green results in 7 OZ of roasted. Takes about 15 to 17 minutes to get roast near perfect which for us is a medium roast with chaff not burned. Took three roasts to get feeling of controls that allow fan air speed, temperature, and time. Pretty EZ to dark roast. Harder to do lighter roasts, as need to adjust fan speeds & power level of heating element. (note: Best to stop roasts a little bit before desired level. Beans retain heat and will coast darker on their own even when in cool-down mode). One of the best things like about this roaster is it provides the temperature reading right on the display. Therefore, can adjust controls and monitor temps to desired roast level. One down-side is this more powerful roaster is louder than older model and can't hear 1st crack very well. (barely audible) If you aim for 2nd crack .. can miss that go past desired point pretty fast. That's why knowing temperature is important. Chaff collector works good but gets quite hot. Use pot holder or gloves to remove. Larger glass roasting chamber makes it easier to see roast color. Cool down in 3 minutes and seems efficient. (additional cooling not needed) Made several back-to-back roasts with no issues. I roast outside on patio so chaff cleanup & smoke not a problem. Excellent fresh roasted coffee!

This is an excellent coffee roaster, in a few minutes you can have Fresh Roasted coffee. Spend a little extra and get the extension tube, efficiently able to roast 1/2 pound (225 g.) each batch. Good control on fan speed and temperature. With the extension tube more than ample heat and airflow for even the most dense high altitude, coffee beans. The chaff collector does a great job keeping the area clean…

Intro Bought this roaster in 2020. I roasted about 8oz of coffee every two weeks or so. This product lasted until September of 2022. Pros If weather conditions are consistent, you could dial this baby in real good and it qould give repeatable results every time. It made the coffee the way I wanted most of the time. Very easy to dial in with fan speed, heat power, and timer settings. Cons Control board started failing at 18 months and could no longer tweak settings. Pretty much became a manual machine at that point where you had to watch and listen closely to what your beans were telling you. At 2 years fan locked up and it was done.. Very susceptible to weather changes. Anything below 45 degrees and heater could not put out enough heat to roast beans properly. At that point run time was very long and tedious. And since beans produce a lot of smoke, roasting inside a closed environment is out of question. All in all giving it 3 stars. Worked good when it worked, but did not last. For $200 and the cost of buying green beans it doesn't save you money. You can get a custom taste for some time though.
