      They have a couple other channels that are pretty good. “Tired Eyes” is good and “Mirror Coffee Roaster” both have some great videos out. Again I truly appreciate you watching. Just finished shooting a video today so hoping to get it out soon. If you have any “topic ideas” let me know and I will put them on my video list.

    1. Charge temperature: increases the turnaround temp + ROR
    2. Preheating time: be consistent
    3. Density (and type) of coffee: affects evaporative speed
    4. Airflow Vs Heat: finding balance affects quality
    5. Fuel: more fuel = more heat
    6. Duration: short roasts are grassy, acidic. Longer roasts baked. Find happy medium.
    7. Ambient temperature (relevant for outdoor roasters)
    8. Drop temperature: affects colour
    9. Batch size: Have one size (larger is better, for control)
    10. Drum size

    Excellent points Rob. Good work.
    My experience seems to match most roasters regarding batch size and that is to keep the batch size as close to 80% of your drum capacity for consistent even roasts.

      @RobPirieCedarOtaCoffee  4 года назад +1

      Yep, I would definitely concur with that. So many people ask what’s the minimum you can roast in “x” machine and it’s like you can roast as little as you want but it’s hard to be consistent changing batch sizes around. We all get it once we start roasting and burn through some haha. How long you been roasting?

    I cook green coffee on my stove In a cast iron pan in about 20 minutes to city roast and it's fine..now I'm doing it in a oven in about 30 , to city and it's awesome . Trick is actually working it . I mean don't walk away . And have a color chart temp chart, a screen to get rid of chaff and don't buy crap coffee. I find that the end result is what you're after not all the variables . I made some mistakes at the beginning but now I'm as good as the corner shop . And I'm totally competent out camping .. don't over think this. The point being is learn to roast with the worst possible scenario possible will advance your skills the fastest. Great equipment coffee by a button pusher is worst then low equipment coffee made with experience. This is the samee for coffee shops .

    Like these points, very good to know. Any chance of making a followup and going through these one by one with concrete recommendations? Might get us started more quickly toward higher quality. I'd guess most of us dont have the time needed to experiment with all these variables, thus roasting just stays in the suboptimal zone. (I'm using a Kaldi)

    Hey brother, do you have any tips for roasting on the stove top in a pot? I don’t have a roaster, so I have just been agitating the beans in a pot with a whisk on the stove. I am using Tanzania beans, and will get the first crack around 13 mins with 460g on high heat. I get that earthy/grassy taste in my beans. I would like to have a nice mellow light roast. Thanks in advance!

    • @RobPirieCedarOtaCoffee
      @RobPirieCedarOtaCoffee  3 года назад +1

      That’s a struggle because there is always contact with the bean. I would say maybe try using a thicker strainer basket and twirling it around over the burner. If you look up the “Hive roaster” you can kind of get an idea of how it would look. You don’t have to buy one but just look up the technique they use with it. Are you using a cast iron skillet or like a stainless steel pot?

    Hi, can we distinguish the main difference between 1st and 2nd crack?
    1. Is there a clear time gap between 1st and 2nd crack such as after 1st crack stopped for some time gap, then follow by 2nd crack?
    2. Judging from the smoke level, can we distinguish 1st and 2nd crack by means of the amount of smoke generated? Which means, does 2nd crack generates much more smoke than the 1st crack?

    • @RobPirieCedarOtaCoffee
      @RobPirieCedarOtaCoffee  4 года назад +1

      Hey buddy! First of all thanks so much for checking out my video.
      There usually is a time gap between 1st and 2nd depending on the fuel that is being applied. If you have backed off fuel and coast in to first crack there can be anywhere from 2-3 minutes between 1st and 2nd. If you have fuel still being applied then it can skip this gap all together and over heat quickly. There will be some smoke during first crack but you will notice a much more ample amount during second crack and after. Hope this helps my friend!

      @@RobPirieCedarOtaCoffee So quick question. How much weight loss is there in a medium roast -> dark roast. 20 lbs of green beans, produces how much? %10 loss due to roasting or more than that?

    • @RobPirieCedarOtaCoffee
      @RobPirieCedarOtaCoffee  4 года назад +1

      Really depends on what level you roast at. Obviously lighter roasts will have less water loss than a super dark roast. A darker roast can have as much as 20% weight loss. It also depends on the bean as some beans are more dense than others and that can help hold moisture in. I always plan for 20% loss when doing calculations. So a 100 pound bag will give me 80 pounds of roasted coffee.

      It differs depending on the bean. Indonesia will be different than Kenya. But... to give you answer. 1 minute after first crack is what I consider a good light roast. Anything over that will get into the light/medium and usually after 3 mins after first crack you get into darker flavors.

    I had recently roasted a batch of Brazil beans which produces a grassy smell, but the taste after brewed is OK. Normally I am expecting nice aroma after 1-2 days after degassing,but not the case. My roast is 1.2 minutes after first crack, air chamber temperature maximum up to 230C. Total roasting time is 7 minutes.

    What type of roasting profile that will cause the "under-develop" ?

    • @RobPirieCedarOtaCoffee
      @RobPirieCedarOtaCoffee  3 года назад

      Under developed usually occurs when the (rate of rise) ROR dips down real quick after first crack. This means usually there was not enough energy going into first crack casing the ROR to drop suddenly instead of consistently. Under developed may also occur in stalled roasts when the fuel is cut trying to drift into the drop but the temp stops rising well before you want it to. Under developed coffee will have a sour or earthy taste. If you have ever smelled silage/ green hay when it is first bailed it can have that scent. Hope this helps my friend!
