Home lab almost complete. Dedicated outlets done and finishing up exhaust system.

What does this green switch on the back of my roaster do??! I have searched the manuals and guides and can’t find it.

It seems to reduce power maybe?!

Started roasting a few months ago, starting to really like the intricacies in it, but wanting to see where I can improve.

These beans are Rwanda Nyamasheke from SM, roasted on a Popper. Mainly drink regular coffee along with espressos.

I’m getting about 16% loss, once I’m done I use a small fan to cool them down and take off any additional chaff. I let them degass for around 12 hours before storing them away. These I’ve found that I need 10-12 days before they taste good, is that normal? If I’m doing espressos I need around 12-14, if not the acidity on it too much.

This is my typical roast for this type of coffee, if I do it darker I find that I don’t need as much time between roasting for a good cup of coffee.

Looking to really understand roasting before investing into anything more expensive, I think the capacity or limited capacity of the Popper is will make me upgrade.

Any advice or other sources I can check out?

Hi, wondered if anybody has a rangemaster handy rack, I have the specific roasting tin, but I’m looking for a trivet that fits inside, V shaped and flat ideally, anybody else had this issue?

For reference, I have the Toledo dual fuel 90

Although the Kaleido M6 does a pretty good job of removing chaff during roasting, I was still finding a surprising amount left behind in my roasted beans. So, I decided to come up with a simple solution using a Bake-A-Round glass tube and a couple of custom 3D-printed parts.

The separator uses a vacuum adapter at the top to draw air through a series of holes at the bottom of the tube. The upward airflow lofts and agitates the roasted beans, allowing the lightweight chaff to separate from the heavier beans and get carried away by the vacuum.

The result is a surprisingly effective chaff separator that removes just about all of the remaining chaff without losing the beans, thanks for the help of a secondary screen at the top of the collector

Hello everyone! After been in the specialty coffee game for years I am now looking to get into roasting. Just for home use and for family/friends. I am looking for the best roaster at a budget for 500 usd. I live in Sweden. I am hoping to get my hands on a decent roaster that lets me analyze the roast with the help of apps or programs but I’m not sure it is possible for that price. Any tips?

Hello!

I’m looking at seeing if roasting coffee is something I would be interested in doing, but I have no idea where to start.

I have been working as a front of house barista for over 5 years and I have always been interested in the process.

Is there a way I can learn to roast coffee without spending way too much money on a roaster?

As well as this where would be a good place to find green beans (UK based) - I want to look for like a washed Brazilian as it’s often quite clear what they’re meant to taste like and I can dial in the roasting process with it

Any tips or advice for starting roasting would be greatly appreciated!

Looking to buy a USED sample roaster for a non-profit here in india. Happy to hear shipping and handling, something durable like a probat brz would be nice

I made this brazil cerrado batch a few weeks ago. As an espresso it tastes decent, not excellent.

But the aroma of the beans have a bready scent to it, more so than caramel or chocolate. Any insight is appreciated 🙏🏼

Hi everyone,

Long time drinker first time roaster here.

I was wondering if anyone had any advice for sample roasting. I’m starting to get into roasting at home, doing small batches on my ikawa and was wondering if anyone had any advice on staring out with roasting coffee?

Thanks in advance

I've been on a Behmor for a few years and by no means consider myself a pro or even knowledgeable, but I can usually get a drinkable roast despite the limited data and control.

I have an itch to step up to something that will allow me to roast a little faster and run back to back roast, but most importantly, a roaster than will support HiBean / Artisan etc and give me actual data. I think the Kaleido M2 Lite will be my next move.

For those to have made the step up - what are some resources that you recommend for learning to "actually roast" - I need to better understand roast curves, RoR, profiles etc but so far Youtube videos have been a mix of wayyyy to deep or not very informative. I want to develop a basic knowldge before I pull the trigger on a new machine. Any tips on taking the Behmor training wheels off are appreciated.

Looking for feedback on this Sweet Maria’s 10 Speed Blend roast on a SR900, tracked in Roast-Tech. Planning to use it for espresso.

• Green weight: 225 g
• Roasted weight: 193.6 g
• Weight loss: 14.0%
• First crack: ~6:55–7:00
• Cooling started: ~8:35
• Development: ~1:35–1:40
• DTR: 19%, per Roast-Tech

I used my saved profile called “6.5m FC,” aiming for first crack around 6:30 -- because I read somewhere in this subreddit that an earlier FC tends to bring out the origin flavors better. I'm not sure I really know what I'm doing yet, but the first few roasts (Ethiopique blend from Sweet Marias) I had with this profile are pretty tasty.

I’m letting it rest before pulling shots, so tasting notes are still pending. Curious what you’d change, especially with the heat increase around first crack. Anything concerning in the RoR curve? Would you adjust the approach to first crack or keep this as a baseline until tasting?

Where are we buying our quality (or at least middle of the road) green beans from? I feel like the prices at Sweet Maria’s have really gone up lately. I know it’s gone up everywhere but I’ve really noticed with them the most. I have been happy with Happy Mug in the past, but I’m just wondering what everyone prefers. I’ll probably be looking for a 5 pound bags just to save some money..

ps: pro cooling tray is still in the box though

I am currently awaiting for my stabilizer as we need that in India (not sure about other countries).

If you guys have a tip for roasting on it please drop as i'm new to aillio

Also any specific youtube channel which i can watch as I'm new to roastime as well

They mention 1.2kg is the limit but the technician mentioned that go for 900gm only ~ what would you suggest if you have an aillio r2 pro?

Open to connect with fellow aillio users so that i can annoy you with my questions (I'll be mainly roasting light, medium, medium dark and dark roasts)

I'm too excited as amazon is going to ship it today and I've got everything done via the electrician about good ampere and kw extension board from the electricity board.

It's beautiful though, As a person who has spent time with lpg based roasters and gene cafe as well.

bruh the title, my bad about it ~ forgot to update it now i can't edit it

I roasted this anaerobic natural process from Laos to about 422F aiming for a light roast. It came out to about 15% moisture loss (I'm assuming because of the processing method?). A lot of the beans came out with the dark spots around a crack at the ends/tips of the beans. I added a photo of the profile

I'm roasting on a fluid bed roaster (Freshroast SR540 with extension tube and thermocouple connected to artisan). The ambient temp is around 65F and humidity around 60-70%

A lot of the beans came out with the dark spots around a crack at the ends/tips of the beans. I added a photo of the profile as well.

Any tips or advice would be greatly appreciated! Thanks all!

First time roasting a Gesha and it came out very muted. I’m looking for any advice on what I can try for the next roast. I tasted it after a 6 day rest and got a faint floral but not a much and what i describe as a beany smell. Same with the taste just very flat and underwhelming. Beany to me is what I taste in an underdeveloped roast not really grassy or astringent though. Beany was the dominant flavor in an expressive light roast coffee I got from a roaster in Arkansas once. My guess is a 30sec longer development. I appreciate any tips as I would like to get the best out of this coffee.
Brewed it with the Hoop 20g coffee to 320g water 205F 4:30min brew

Peru Organic Guardian del Bosque Gesha washed
Aillio bullet R1V2

My Bullet is losing the connection to my laptop via the micro USB cable. I had to squeeze the roaster end plug to get a more reliable connection. Then I saw Sweet Maria’s has an updated control module with USB C. It is $270, which isn’t exactly cheap but well worth it if it fixes the problem. It is supposed to arrive tomorrow. I am stoked! You need to give them your serial number before shipping as it needs to be flashed to match your roaster.

Hey everyone!

Looking for affordable, ideally stackable cupping bowls. Anyone using IKEA bowls or have other recommendations?

Also looking for some containers to store beans/samples after roasting before packaging.

Preferably available in Europe.

Would love to hear about any other useful roasting tools or cool finds you recommend!

Hi all, we're selling our 20kg Typhoon. It's been in our showroom for 2 years. It's been roasted on very little - maybe 100 roasts or so. $79,000 plus shipping and crating for the roaster, loader and destoner, and we'll throw in the electrostatic filter for free. We also have a transformer available if needed. Happy to answer questions about it too. It's in St. Louis, Missouri, USA

Anybody know the nut size for these screws ? Not sure if I lost it or it was missed in the box.
