    @randytsuch I’m late to the show with for your question, but I have very strong opinions on automatic drip coffee makers. The Technivorum are the best for home, but these are out of most folks price range. I’ve tested everything from the cheapest to the best for home. My top recommendation is the Technivorum, but I don’t recommend that people save up for it. Instead, I recommend the most basic 12-cup Mr. Coffee maker with no fancy features. It’s $33 on Amazon right now. All of the machines in between the Mr. Coffee and the Technivorum make the same conceptual brewing mistakes. Once you hit the Technivorum level, the machine starts controlling water temp properly. Anything below that in price point seems to pull the water temp up to 115c at certain points in the brew cycle and down to 85c at the lowest point. The $33 Mr. Coffee has this issue, but so do all of the $100 and $200 brewers. The Mr. Coffees hold a more consistent cup from machine to machine and last longer than all of the <$200 brewers I have tried.

    The two Behmor Brazens that I’ve owned have not seemed to have had this issue.

    I have not tried the Behmor Brazen, but that looks legit and I bet it makes a great cup based on the specs. At $200 though, this is what I’d expect. This looks like a really good option between the Mr. Coffee and Technivorums. I’ll have to remember that model for the $200 range.

    It’s been four years since I really tested automatic brewers, but the $200 category seems to look a lot better now.

    Ended up getting a Cuisnart from Costco because it was on sale so price was right. Picked this because of Costco's return policy, if it doesn't do a good job, then easy to return. Its a Christmas present to me, so can't use it for 10 more days.

    My other coffee news is I've decided to start roasting again. Its been about 10 years since I retired, but want to try again. Learning how Artisan works, then need to put something together. Want to use the PID function on Artisan, and interface to an ESP then will measure temps and control the heater.

    Okay, question for the masses regarding brew times.

    As I go through the Onyx advent calendars, I'm noticing what I've seen in the past...with the same grind size and identical technique, two different beans will take vastly different brew times.

    With some of these, I'm down around 2:30. Others are taking as long as 3:30. 2:30 to 3:00 is my ideal, but I'm noticing some of these coffees that take longer are not tasting over-extracted or problematic in any way.

    Any idea what feature it is in the beans that causes this? It is the variety of bean? If so, do we know which beans specifically tend to take longer than others?

    There are a lot of things that can affect how a coffee brews in this fashion, but the various variables mostly affect how the grind profile comes out during grinding. A lot of it is related to (1) the processing method of the coffee, (2) the density/ hardness of the coffee, (3) the varietal, (4) the age of the green coffee, (5) the amount of chaff removed from the process during roasting or grinding.

    I’ve noticed that a lot of East African natural process coffees have been producing a lot fines when grinding over the past ten years. Most natural process Ethiopian coffees seem to produce more fines than they used to.

    Here are some SEM cross sections of different processing methods and different ages of green coffees. You can tell that these will produce different grind profiles just by looking at the structure of the bean:

    Cool, that makes sense. It also explains why bumping the grind size up a couple of notches doesn't really accomplish a lot. Those fines are still in there slowing things down.

    Like I said, it hasn't had a negative impact, but I've always found it interesting.

    Thanks!

    Recently re-bought from a roaster I have liked in the past and the beans have just been "ok".

    Luckily, this has been balanced out by a wonderful local coffee shop and their source for beans.

    A couple of shoutouts for standouts...
    Bay Area spot Lookout Coffee.
    Their bean source Passenger Coffee.

    Have had great Kenyan (one washed and one natural) as well as Colombian Divino Nino Gesha at Lookout. Bought a small lot of the Colombian Gesha to test my home ratios and process. Will be buying some Kenyans from Passenger later.

    For me this is really educational. I can enjoy what I consider to be an incredible pourover cup made for me at Lookout and then see how close I can get to those cups at home.

    I have enjoyed beans from Passenger in the past. Ethiopian Ganale Dulacha natural reserve. I agree they are a quality roaster.

    I see the Danny Moreno coffee listed on the Sey website. I'm drinking the same beans right now, but from Onyx.

    It's interesting to me to see how the same beans by different roasters are listed with pretty uniquely different flavor profiles.

    Ooooh what roaster did you end up getting? [EDIT: nevermind, i mis-read that as you bought a roaster, not bought from a roaster.]

    I had an Ailio Bullet a few years back that I sold and now regret. I went through the progression of Poppery 2 --> Behmor --> Hottop --> Aillio Bullet and felt like I could never get that same level of brightness as pro roasters until I went to the Aillio. Units like the Aillio or Huky just give you way more customization to let you really dial in the roast profiles.

    With that said, I loved the Poppery results, just batch size was the big issue. I was roasting every other day pretty much.

    Would love to see your list. I've been ordering from Onyx and West Oak mostly the past few years, but would love to give others a shot. My favorite roaster locally to me (States Coffee) is good, but a notch below the others.

    I’ve roasted on a Poppery 1 and 2, Freshroast 8, whirlypop, SC/CO and Behmor. The SC/CO gave the best results by far because I controlled temps so closely and roasted to strict profiles. It teally did take the roasts to the next level. The Behmor was the most convenient but definitely did not have as good results. I haven’t tried the updated Behmor, only the original.

    Here are some old pics of the SC/CO that I just happened to come across last week

    man the glass really needed a cleaning when I took this one! I actually did clean it regularly with Simple Green.

    That’s awesome. I never tried the Stir Crazy. Of all of my roasters, the Poppery was the most fun since you were right up close to the beans. I did all sorts of tricks to adjust the charge and roast times. I haven’t roasted in a few years but if I ever get back into it, i’d probably just keep it simple with something like that again instead of a big drum setup.

    My current coffee project is turning a Gaggia Classic Pro into a Gaggiuino. This has been a very fun project, and while I have done everything in the scope of the project, I’m less than halfway done. This project is neat, but it’s a hot mess and the documentation is utter trash. None of the wiring or casework has ever been properly done. The bill of material is never right or complete.Much of the design looks like it was made by a software developer that knew just enough to be dangerous with electricity.

    I’ve been working on designing cases and fixing some of the circuit designs for it. I still need to clean a lot up in my current implementation, as it’s just hacked together right now. This is just to get the current version out of “hot mess” state. My next stage is design a carrier board for everything to drop into and mount in one case with a lot less wires and no Wago connectors.

    For my next project, I want to design a recirculating fluidized column roaster from scratch. I want to use an Arduino with a TC4+. I’d love to integrate with Cropster.

    I should sell some audio stuff and pick up a Niche grinder, not to be confused with Nitsch.

    i did a lot of tricks too. It’s the only way! What that style of roasting really lacks is the ability to do a drying cycle first. That was thing about the full control of the SC/CO. The Behmor could do the drying cycle but then I felt like the ramp-up after was never quite right, not fast enough or hot enough or something. I wonder if the updated one is better in that regard. I know it has more control.
