Well, good info on that link, but I guess I need to figure out why I reach the start of FC at about 4.5 minutes. This was the 3 minutes of "drying" and the 1.5 minutes of Medium heat/High Fan.

I "could" try putting the beans in our oven first as a drying phase at 300 but I think that is going overboard. I believe I will grind some of this 2nd roast tomorrow AM to see how I did!

So in my recent SM order I added a pound of Ethiopia Dry Process Yirg Adado Sulula at the last minute. Thinking this might be my last hurrah with Yirg coffees, as I've really not been able to nail the roast. I have to brag that tonight I did it. I nailed the roast for this Yirg to perfection and daaaayum is it tasty coffee. Right out of the roaster I tossed a few into the grinder to do a quick cupping. The smell of the dry coffee was sweet and smelled like BLUEBERRIES. I was really excited about it. I added the hot water and BOOM the sweet berry flavor continued. Then I slurped up a big spoonful, BAM, blueberries, super sweet, and a hint of cocoa. This is the tastiest coffee I've roasted so far. It will be an amazing treat tomorrow morning. I should have bought 5 pounds of it, because SM is now out.

Roast profile for the Ethiopia Dry Process Yirg Adado Sulula from Sweet Maria's
114g charge
Every 30 seconds I flicked to cool for 5 seconds until the 3.5 min mark.
Start with low heat/high fant. I switched to medium heat/high fan at 4.5 minutes. Switch to high heat/modulate fan at 5min 50 seconds. The crack lasted until 7.5minutes. I switched to the cooling cycle at 7min40seconds and moved the beans to my cooling bucket at 8min20 seconds.

Yellow 4min
Tan 4.5min
First Crack 5min 50 seconds Ending at 7.5min

Crack started off soft and was quickly rolling.

Anyway, I'm glad to have finally roasted a DP bean to perfection. Also this goes to show that buying a quality bean is worth it.

Glad to say I've now found a good "treat myself" coffee.

So, every 30 seconds you went to cool for 5 seconds for a total of 3.5 minutes, then at 4.5 minutes you went to medium? I guess I wonder what you did from 3.5 to 4.5 minutes?

I DO have an Ethiopian, but am sticking with this Colombian for 2 more roasts.

OH...I ground my second roast this AM. WOW was it good! I may add 12 or 18 seconds at the end, but this was good. My only "problem" is that I did the cool 5 second thing at 30, 30, and 1 minute thing then Medium for 1.5 minutes at 3 minutes. So, total was 4.5 minutes at the END of this stage before going to High Heat and a modulated fan. Even at Medium, I heard a few beans at FC. By the time I went to High heat, I could only keep it there for about 2 Minutes, so total roasting time was about 6.5 minutes. I then hit cool. I MAY try keeping it on high stage for 12 or 18 seconds longer as it "could" be a LITTLE darker, but I liked this 2nd roast a lot!

SO, I do not know what extending this would do, but I can get nowhere near 10 minutes of total roast time.

It stays at low heat/high fan until I move up to medium at 4.5.

The best part of roasting is dialing it in to exactly what you like. I agree with your decision to stick with the lower cost and easier to roast Colombia beans. I wish I'd done that instead of ruining 2lb of Yirg. :/ Live and learn.

I decided that I'd roast 6 batches today. Each one 114g. 2 of the 6 were beans I've roasted before and will provide a good standard bean. One was specifically roasted darker for my wife who prefers something a little darker than I do. One is a decaf, which went quite a lot darker than I intended but I'll likely drink it up.

It was quite and experience to roast up 6

Anyway. I happened to be at a friend's place, she does this great recycling thing, where she brings how interesting bits and bobs from her work and then offers them up for free on a local FB group. I was there to pick up some buckets to make more garden buckets and saw that she had 1 pint glass jars with black plastic lids, and the right number for my coffee storage needs. I got them home and managed to break one of the 6 jars. Too bad. Anyway. Eventually I'll add a vent to the top of each of these lids but until then, I'll be using canning jar lids that I'd added a vent to. A little chalkboard label and a white colored pencil and BOOM, perfect coffee storage.

The salsa jar in the back holds the decaf.

OK, I was referring to this...where you said.....

High Fan/Low heat for 3 min. During the first 3 minutes I flip to cool for 5 seconds at 30 seconds, again at 1 min, and at 2min. This seems to keep the roast even.
at 3 minutes I switch to medium heat/ high fan for a minute and a half
at 4.5 minutes I switch to high heat and modulate the fan


Here you say you switch to high heat at 4.5 minutes not medium.

Also, we have a few bags with 1 way valves. Then we use canning jars and use a FoodSaver to vacuum and seal them.

I'm not sure which profile you are referencing, I assumed you were asking about the most recent, for the Yirg Adado, which is

I use a general profile for the first roast of any bean, but vary it to change up the flavors and if a bean seems to progress differently.
 
MPSAN
OH, I was just using your "guide" in Post #1.
As I said my 2nd roast tasted great, so I will modify it! Grin See my SIG.

I will roast a bit longer for roast 3. After roast 4 I think I will try the Ethiopian! It too was dry processed.

Every bean is different and will need a slightly different profile. What I initially posted is something that is really basic that can be easily adapted, even on the fly as I roast if I see that bean is behaving uniquely.

Or I can plan to tweak it when I read the cupping notes for the bean. Using the Yirg Adado as an for instance, I knew I wanted to try to get the berry flavors, so I wanted to push from TAN to 1C more quickly than say with my Mexico la Lagunilla (MLL). With the MLL I wanted to emphasize the chocolate and molasses sweetness, and so I want to increase the time from tan to 1C.

Mostly I stick to my basic profile, unless I know that a bean is special and needs something different.

Hope that makes sense.
 
MPSAN
Yes, it does. I can not be too far off, however.

My 3rd roast...and even my 2nd...were VERY good. Anyway, how long should I let the SR500 cool between roasts. I would like to roast 8 oz, or even 12 oz, at a time. Is letting the top get cool enough to pick up and brush between roasts cool enough? Can I use the same profile on successive batches?
"If it Ain't Broke, Fix it 'til it is"!
 
comfortableshoes
I let mine go for an hour or so, sometimes 30 minutes. Supposedly it'll burn out prematurely if you do back to back roasts.
 
MPSAN
WOW, that does take a bit...well, I guess 1/2 hour is OK. I wonder if it would help if I clean the top and hit COOL again?

Well, I will, but doing this will not tell me if it has cooled enough so there will be no damage.

This site has been a great help to me and has made my roasts easy.
I suppose that even if the SR500 does not last as long as expected, it should still be long enough before I think about a drum roaster. They do cost $$$!

you do not need a drum roaster what you need to do is to trust yourself and play a bit. no roast will ever be the same. close maybe, never the same.

I think you are spending too much time on how and not why (you like the coffee from fresh roasted)

just play with what your gut tells you, forget the numbers and the time, look, smell and feel that roast M...

I would call you by your name but do not have it...

ginny...I am playing, but now that I am getting great results I just wanted to get advice on how long to cool the SR500 between roasts. I sure would like at least 8 OZ instead of 4OZ.

M:

listen up guy, I did not mean to be egregious with you - I just want you to be ok with your process of roasting as it is different for each and every one of us...

it is, really. soon you will just know what is right with that particular bean you may be roasting and I don't want you to get caught up in other profiles as it can really mess with you and make you think your wrong.

nothing is wrong with your roasting you simply have not developed and felt YOUR STYLE yet.

relax, enjoy the sight, the smell and the end result of your craft.

hugs,

ginny

Yes, this 3rd roast smelled great even when I opened the valve bag after about 40 hours. Anyway, I still am trying to determine how long to cool the SR500 between roasts!

well, I need to ask you if you MUST roast right away? if not wait an hour and roast or until the darn thing cools.

are you in a hurry or do you need to back to back roasts?

I roast 10 ounces in my Hot Top, walk away after it dumps and come back when it's cool as I am not on any clock and it is not an issue. so many here have done mods to do back to back roasts.

if I wanted to roast for the masses I would get a big freaking roaster.

just curious m...

I have been using my machine/roasting as a moment to recharge and unplug my brain as I'm reading heavy research for my thesis. I read an hour, do a roast, read an hour, do a roast. Repeat until I finish my roasts for the week. I'm also roasting 6 different types of beans.

I've been testing out some new "ramps" to replace the copper ring in the bottom of the chamber. I managed to crack my chamber because I didn't put a gap into the ring at the top of one of the mesh tea balls. (A 3 inch mesh tea ball ripped in half, fits in perfectly with a little bending of the ring. A gap cut into the ring would have made it work and not crack my chamber.) Sigh.

Great...well, I just wanted to know how long a delay should be for back-to-back roasts. I can wait an hour, that should not matter.

I guess I will see how much of a pain these back-to-back roasts are. I have looked at the Hot Top for a possible future roaster, but they say they are difficult to clean.

Well, reading for an hour between roasts seems like it works for you. Grin

Anyway, regarding the rings...I had read about them, but during my first 3 minutes of low heat high fan, with the 5 second cool, I tilt the roaster front to back and left to right and right to left until there are no signs of beans hanging up. I do not tilt enough for any issues with damage to the top. This seems to work as I nave NEVER had a single bean hang up and burn, and seems to only be needed a few times while drying. During this time the top is still cool enough to do this.

The Roast Rwanda Inzovu Gasabo is worth the money, and made the purchase of their sampler worth it. This bean roasted to City/ City+ (It roasted very unevenly) is a cup full of juicy peaches and nectarines with a clear lemony finish, full juicy mouth feel and just a darn fine cup of coffee. I did NOT expect much from it. Beans scorched and it took forever to get moving well in the chamber (pre breaking it) The 1C never got rolling. It was a PITA to roast, but oh man, soooo good.

I used my standard flicking the machine to cool every 30 sec for 5 sec.
Hit yellow at 4:30, tan at 5, though this was hard to judge because the beans were very odd in the roaster. 1C at 5:15, and possible last at 7:30 when I finally ended it, afraid I'd hit 2C.

114g
Start: low H/high F yellow 4:30 tan 5:00
5:00 med H/high F 1C 5:15
6:00 high H/modulated f last C 7:30 heat off 7:30
7:30 cool for 30 seconds, then beans to my homemade cooling bucket for 3 min.

Final weight 99g for a change of 13.2% in weight.

Roast's tasting notes don't really give an accurate description of the flavors I'm tasting in my Hario V60 brewed cup. Sure there is some cocoa and milk chocolate,but the flavors of peach and nectarine dominate.

I might drink this entire pot before my wife even gets out of bed. It's that good.
