    Advice needed: Behmor 1600 and Silvia V3

    Gene Cafe Coffee Roaster $850 - Free Beans Free Freight
    Hi all. I've been roasting for about 5 years and have had my Silvia for about 7 years and also have a PID on it. I'll admit I know very little and reading through some threads just gives me a headache and highlights how little I know. I generally roast about 200 grams at a time and usually just go P2 and B, press go, wait until very first hint of second crack and press cool with the door open. I visit a really decent coffee shop a couple of times a week and then I come home and feel really disappointed with what I produce. Should I upgrade to the 1600+ control panel and follow someone else's formula or is it worth upgrading my machine? That all said, I recently bought some of the beans used at my local and the result at home wasn't much different to what I normally get with my beans. I followed someone's advice on here and tested my brew head temp and adjusted it to about 96, does that sound right?
    Thanks guys.

    The upgrade to the 1600+ panel is worth it as the Behmor manual mode gives you more control over the roast. However, given you couldn't obtain good results with the commercial beans suggests your brewing technique could be improved.
    What sort of grinder do you have and how old is it? Also, how many coffees do you make daily?

    I have never used a PID so can't advise but you are aiming for a brew temperature of 93-94 degrees. This is the temp of water coming from the grouphead, not the boiler.A too low brew temp can lead to unsatisfactory results in the cup. If your PID is measuring boiler temperature, you may need to set it higher. Other PID'd Silvia users may be able to tell you,

    Cheers. I have a decent la pavoni grinder and the burrs are still good. I ignore the value the pid shows and I adjust it until I get 96 on my multimeter through the bead probe. Maybe I should get some roasted beans from Andy and compare.

    Just my opinion from my experience. I have roasted for a little while with the behmor 1600+ and about 8 roasts ago I purchased the heat snob and the 100 mm thermocouple . Mounted it into my machine as per the location Andy advised on a post on this forum. The difference in my case is inmeasurable IMHO . Connected to my old laptop running roast monitor the control of the roast is unbelievable . You can do so much and have so much control over the roaster it’s much much much better results for me anyway . This then translated to the cup for me, now I sorted a few brewing issues . I am very inexperienced in the world of coffee but my roasts now are the best I’ve managed so far . Good luck

    I doubt it but probably worth giving Andy's beans a try just to give you another perspective.
    Have you noticed any improvement after raising the temperature?
    How are you using the bead thermocouple to measure the water temperature?

    I was planning on dropping the temp to low 90's actually. For the temp measurement I followed the method given on here by a few people. Cheers

    Thanks, will give it some thought. There's only so many hours in a day I guess. Maybe I'll try some other beans and decide if I want to put the effort in like it sounds like I need to get the results I'm after. Thanks.

    96deg is on the high side for group head temp. I’d suggest it’s maybe ok if you’re brewing very light roasted single origins to drink as straight espresso, but if you’re using something that is better described as ‘espresso roast’ then you’re almost definitely too hot and will be over extracting.

    I don't think you'll find a perfect one size fits all solution as far as brew temp settings goes. 93-94 deg is the mean starting point but different beans and roast depths will have slightly different temperature sweet spots. Use your PID to adust temp up and down to find the sweet spot for each bean you use (Maybe 2 deg + & - increments initially until you find the sour/bitter temp range points then fine tune). On a Silvia you're measuring the external wall temp of the boiler which gives you a good reference for incremental changes. You'll need to allow some time after each PID adjustment for things to stabilise and maybe a flush or 2. Have a consistent routine. Focus on what you taste in the cup and use the temp readouts as a guide rather than an absolute I'd suggest. Maybe buy a proven roasted bean (Andy's for instance) to see how this process plays out so you then have a solid foundation for dialling in your own roasted beans.

    Obv there's insufficient info to advise definatively....
    But if your preferring the taste of something at a local cafe (LC), chances are
    I'd be reviewing the Barista process....
    Basket Size? (LC - likely 20-22g)
    Yield ? (LC - prob 1:2 ristretto, in around 28-34sec)

    If you dont have deep handles for your Rancillio to fit a 20-22g basket,
    look up local sponsors and my reco would be a HQ Dble basket .
    With these Your likely to be able to dose up to 19g in your machine,
    without *touching the shower screen ( look up 5c test).
    A matched Tamper (to the basket) with a flat base. Tick.
    And your away.
    Weigh dose in. Shot weight out.
    Take note of shot duration / volume. Experiment to suit your taste.

    If a white drinker....experiment with total volume of finished beverage / shot volume..

    You'll get there. Eventually.
    GL

    PS Roasting...compare your roast n the CS'ers color Scale.
    If ts towards the Dark side into #9 ...try a roast or two where you cut it a Rolling 1st Crack. A Medium Roast

    I'm interested in how your roast has improved. I've done over a 100 Behmor roasts and have been thinking about the heat snob update but I suppose I need some convincing. My standard roast is KJM, approx 340 grams, and I'm not sure it could get much better then I'm currently doing

    Cheers. I use a 21g basket in a naked handle. I have a good flat bottomed tamper that fits perfectly. My extraction time is normally 30-35 seconds for 30mil. I think I may be going too dark in my roasts and also my water temp is a bit hot. My PID has been playing up so I'm waiting for a new one and then I'll spend some time on it and report back. I think I'll order the updated panel for the Behmor and follow some methods for specific beans. I don't know anything about using software to control the roast, so guess I have some learning to do.
    Thanks.

    Seriously im no computer guru very much an amateur but the thermo couple fitting is simple and the software to load and use is really really good . Andy and graham K have set this up incredibly well . You will not be sorry . The only issue with the fitting is the drill sizes for the hole through your machine is to small . It’s talked about in forums so just make it fit . Easy as mate . So easy to use you will love it

    Behmor Coffee Roaster
    Sorry for the delayed response. I just used the forum post under Home Roasting . This should be the link https://coffeesnobs.com.au/home-roas...-software.html . Try this if not one of the forum regulars could help you out possible but the link should put you onto it. Mate if I can set this up anyone can . Good Luck
