VERY helpful! I was gifted the 540 for Christmas and am just beginning to learn about roasting at home. I was initially so excited- until I started researching how to actually roast.... I've honestly been overwhelmed with all of the variation that can go on between times/temperatures/fan speeds/bean variety/etc., and disappointed with how my batches were turning out. I've watched a LOT of videos, but yours helped me really wrap my mind around the process. Thanks so much for taking the time to organize this so well- the split screen videos and the chart at the end were just what I needed to get started with a little confidence. Thanks again!

Oh hey. It's Keith! Haha. Just happened to come across your video

I found with any electric roaster (besides maybe some smart roasters with a ton of sensors) in North America at least with 110-120v outlets some outlets ARE better than others and it does affect heat levels. Ambient temperatures contribute as well. If you find your roast times are too long or temperatures are too low, the best outlet to use are the ones on an electric stove, I don't know if a lot of newer models still have it but older models will have outlets on the stove, and because the stove uses a higher amp plug with less or no shared outlets (dedicated line) I think it gets the most power that way. If you use an extension cord just make sure it's a heavy duty high power thick gauge one!

Thank you! Maybe someday I will. Best advice I can give is to work out a profile you like for a light roasted regular washed coffee (or whatever your favorite profile is, leaning toward light). Then on roasting day, run the regular bean through first to make sure nothing funny is going on with your power supply. Make sure you write down time and settings along the way, when you changed fan and power, when you ended the roast. Then assuming all goes well, run the decaf bean through and only use the time and settings, including ending the roast at the same time. Don't change the settings based on what you see and hear (or don't hear, decafs sometimes have a quiet first crack for example). So end the roast at the time and setting you normally do, not based on sound or color. Don't keep going because you didn't hear first crack, you may not hear anything. Don't pass judgment or change settings until you've brewed it and tasted. If it's a Swiss water the ending roast will look dark and kind of a non-shiny, matte type surface. If it's an EA sugar cane process, it will look a little marbly dark a D light brown and usually appears shiny, even though there may be no oil. Neither will produce chaff.

Thank you so much for getting back to me! I roasted a batch the other day (haven’t tried it yet), and NEVER heard a crack, so I’m glad I’m not crazy. Also no chaff threw me, so glad to have that verified also! 😁 I will follow your directions, and I’m sure it’ll be great because you really know what you’re doing. I have a few Costa Rican regulars and a few decafs but of course none the same, but hopefully the region at least should produce a similar result. I will update…again…thanks so much! I probably would have made a mess of a bunch of beans without your helpful videos! 👍🏻

I start at 8/1. I've tried this method and it isn't for me, though I do decaf so that is in there. Either way I found ramping up during the dry phase slowly pays off with more control before 1st crack

Very helpful but the beans still look greenish after roasting and still in the SR540. Must be the colour balance of the lighting. Colour looks must better in the trays.

The Ethiopian coffee is killer

Thanks for doing each. Very interesting in the natrual you roasted to med. Couple questions if I can ask 1. How do you think this applies to the SR800 with 50 more grams to start off ? I am thinking just each step might taking a little more time ( maybe a 1minute ? ) 2. I see a minute after 1st crack begins you add heat by dropping the fan for the final minute. Is that do to the roast stalling ? Thanks

@keithpoolehomecoffeeroasti489

4 жыл бұрын

From what I've heard about the 800, it's similar but with larger batches you may want to preheat the machine (like fan 5 power 9 for a couple minutes), change to fan 9 power 9, drop in beans while it's running, then start reducing fan as soon as you see decent bean movement. Keep reducing fan every minute or so, or even faster...basically get the fan as low as you can as fast as you can without making the beans stop churning.

All three of your videos are very helpful! I also have the Freshroast SR540. I have never used any of the bigger roasters like the Behmor or the Hot Top or Quest. Do you think the main advantage of those is bigger batch size? Or can they give better flavor, body, etc? I just ordered some Yemen Haraaz Red beans and would like to get the most out of them. Do you think the Freshroast can do the job. If so, for a light to medium roast(city+) which of your profiles would you recommend trying first? Thanks!

I think the settings I use for the light roast in the video are going to be the closest. Most other profiles I've seen for the 540 go longer in overall roast time, not shorter. Only other suggestion is to leave heat at 9 and reduce fan to 8 at 2 minutes, then fan 7 at 3 minutes, that would shorten the time.

Thank you! I realized I could just use a digital thermometer to compare the two units and will share the results here in case anyone else is interested. The carafe from the SR540 fits onto the old SR300 so I used the same one on both machines. The SR300 (single setting for fan and heat) temperature fluctuates between 350-360F with the top off and the temperature probe suspended just above the bottom of the carafe. Several variations provide the same temperature range in the SR540. At 9,9 (fan,power) the SR540 runs at a constant 350F with the top off. Other results, each one measured after 2 minute run: (8,9) 367F; (7,9) 376F; (9,8) 350F; (9,7) 345F; (9,6) 336F; (8,8) 358F; (8,7) 355F; (8,6) 350F; (8,5) 341F. Will need to experiment to see how the larger carafe size affects the outcome but (9,9) seems a good place to start to duplicate the SR300.

It's hard to give really specific recipes due to different line voltage, but try starting fan 9 power 9, reduce the fan one setting about each minute until you get to the color you like (or when you get close to second crack). This might be too fast but will give you a starting point or base line on how your roaster and outlet respond.

I have my first beans arriving today a LB of Ethiopian and a LB of Colombian. I am going to do the Ethiopian the same way you did the light roast. When you say COOL from 5:00-5:30 do you mean you press Cool and leave it in for 30 seconds? Or did you take the beans out and dump them at 5:00

I mean depending on the bean and how it's progressing, I usually hit the Cool button somewhere around the 5:00 to 5:30 minute mark, give or take (using all stock equipment). You need to listen for cracks and watch the color to really decide. After I hit cool, I usually leave the beans in the roast chamber but lift off the chaff lid using gloves as soon as I can. I then let it run at Fan 9 for about 1 minute.l of the 3 min cooling cycle. After the first minute of the cooling cycle I dump beans onto a baking sheet and let it cool under a fan.

The base unit display temp is usually 450 if it's a faster roast (like 5 to 6 minutes total) and maybe 425 if longer (7 to 8 minutes). When I use a bean temp probe it's about 425 to 430, with first crack around 405.

Hard to say without tasting. Generally speaking, air roasters have shorter overall roast times vs drums, so to get proper extraction in espresso, you might need to experiment with different profiles that go longer and maybe a bit more developed.

I've never hit first crack at fan 9 power 9 either. I usually drop to fan 8 by around 2 to 3 minutes, then fan 7 if needed to go fully into first crack around 4 minutes. When roasting spin the dial to get temp readout. Try to get to 400 degrees on base unit by around 2 minutes and 420 by 3ish minutes, then get it up to 450 or so at 4 minutes to push into crack. You do this with fan reductions. You can leave power at 9. These machines are sensitive to line voltage and ambient temperatures. You may need to go as low as fan 6 or lower. Good luck.

I’m curious how you would change the formula if you observed first crack coming a bit later. Specifically, for the light roast, if frost crack came 30 seconds later than what you have listed in the chart, how would you change the times for decreasing the fan and starting the cool? Would you just leave it at 99 for an additional 30 seconds?

@25kpoole

Жыл бұрын

You can adjust times based on your actual experience. Beans and your power supply will change how everything progresses. If things seem sluggish reduce fan more in order to add more heat. If crack comes sooner then just end roast based on your desired color.

@pimacanyon6208

I believe some roasters key off of first crack like this: They will continue roasting for 1 minute after first crack begins. Or 1 1/2 minutes, or 2 minutes, depending on roast level they are trying to achieve. Those who roast this way count the beginning of first crack when they hear several of the beans popping at once. You may get an outlier that pops early, but they don't consider first crack to have started until several beans start popping. But as Keith said, the real key is color, ending the roast when the beans are at the color that indicates the roast level you want.

Sorry and what does adjusting the fan settings do?

@keithpoolehomecoffeeroasti489

The beans move faster or slower but more importantly the temperature goes up or down. On my roaster if I decrease fan 1 setting the temperature in the roasting chamber goes up about 15 degrees F.

I find it to be extremely difficult to roast with this roaster. I get inconsistent results. I’m either stopping to early, or the last time I used it I let it go too long and threw out the beans. I also have a Hottop and a Behmor and far prefer them. I watched this video, and will be watching others to get more tips on managing the roasts from the SR800. It is so loud it is hard to hear the cracks. There also isn’t much time between first and second crack.

Have you tried using the chaff lid expander? I had some of the same troubles you are having, especially at the end of the roast, where chaff gets clogged in the chimney. Also make sure you make note of the display temp on the machine. If a roast is too dark, next time make sure roaster is running 10 degrees or so lower, then just keep trying batches at lower temps until you have a good result.

Are there advantages to starting up cold?

You just have to try pre-heating vs starting cold and taste and see which you prefer. For consistency some people always preheat at least 30 seconds or so.

I noticed that when I use my own roasts for pour over, the bloom is very large - no slurry, just a dry dome. No matter what technique I use, the end result is undrinkable. There seems to be a lot of gas left in the beans, even after a week or two. How long does it usually take for beans to degas to the point where the coffee is drinkable? I have used a few varieties with the same result. Also, would you kindly share your recipe for pour over? Finally, what is your preferred method for your morning cup? Thank you for your attention!

It might be the roast like you said, I don't have that issue of dry dome and undrinkable. On the 540 I'm normally getting the machine temp up to 450 to 460 during first crack. My usual morning coffee is made with an Aeropress using the Tim Wendleboe recipe, it's on KZread but basically 14 grams coffee to (200?) grams water. For V60 I like doing a 30 second bloom then use the 'several small pours' method where water level never gets high up in filter, just do 50 to 75 grams of water each pour to keep grounds level and keep adding small pours so you don't see the coffee bed until the end.

Hey Keith excellent video! I recently purchased a Fresh Roast sr800. My first batch was a Mexican coffee. I preheated my roaster to 350 f and charged the roaster 200g (80% capacity). My target was a 10-11 minute roast achieving city plus. I reached full yellow @5 min and began the development stage. I hit first crack @ 8:30 and dropped the beans @ 10:30 just at the end of FC. I was really happy with the color, evenness and fragrance. The first cup I brewed was surprisingly good for a first try. Roasted peanuts, cookie dough, green apple acidity. Very bright. Unfortunately after a couple of days the flavors seemed to disappear and the acidity increased to the point of being intolerable. I brew with a Hario V60 pour over. Not sure what went wrong. I would have roasted a little longer but I didn't want the beans to get any darker. Any thoughts? Thanks so much in advance!

What temp does your roaster show if you run Fan 9 Power 9 for 3 minutes with no beans, chaff lid on like normal? Mine shows about 370F currently but has been as high as 385 in non-summer months.

I did 130 grams at 9,9 for 20 min and it still didn’t look dark. Couldn’t hear the crack with the noise. Is it because I didn’t lower the fan? I’ve gone as far as 30 min on 9,9 and still not as dark, medium at most.

I think it depends on what you like and what you are sensitive to. For small batch air roasting (like Ikawa, Fresh Roast) roasts can be fully developed, sweet and juicy, with pleasant acidity, in 5 to 7 minutes no problem. Personally I'm more sensitive to baked flavors, and I tend to notice them creeping in after about 7 minutes. I've done several versions of light roasts closer to 9 to 12 minutes, and nearly every one has crashed RoR type baked notes (flat, dull, hollow, roasty, papery, not sweet). Sometimes it's just a little, sometimes a lot. You just have to try several profiles and taste side by side to see what you like.
