I would advise roasting further and backing off in subsequent roasts, rather than going for a roast this light on a new coffee first thing. This is especially ture if you are not used to the smells of a roast ready to drop -- sniff the beans in the tryer before dropping -- they should smell sweet, not vinegary or

Welcome to HB John! what was your charge weight for this roast? Are we talking about a solid drum or perforated drum? if you like light roasts and you're spending 1+ minute post first crack, then id hesitate to say that you might want to adjust your settings to spend more time in the middle phase of the roast

I have dial indicators, how did you set it up? I also am thinking about throwing it on a CMM machine at work so I can also check coaxiality of lower burr in relation to carrier threads but seems a little too complex for me I also wonder it it really matters because of the design of

Hey guys I'm new to roasting and have a question about my coffee roasting technique. I have only roasted a handful of times but each roast I do tastes underdeveloped and grassy. I prefer light roasted coffee. Here is a picture of my last roast. The beans are from Brazil. I have a 1.5 kg drum roaster. Do you think

Hey Alex, Welcome to HB! Have you verified there is still power on the outlet? If it's plugged into a GFCI/RCD, it is possible the outlet tripped and it simply needs to be reset. Do you have any indicators on the machine at all? Standby should be a slow blinking red light. If the outlet is good and the

Ok, so upon further investigation, I decided to bypass the HX by using the tube that goes from the water tap to the outlet spigot (as it was the longest tube) to connect the pump/opv outlet directly to the brew boiler. Gurgling and bubbles completely gone. Immediate water flows through the group head as soon as I press either

Yes. This is all true for the steam boiler. In the case of the heat exchanger in the steam boiler, there is no steam within. Since the heat exchanger circuit is totally flooded with water, as soon as the water begins expanding, the pressure skyrockets. The steam boiler pressure corresponds to a specific temperature that the heat exchanger

I'm not sure I follow your question. The Gagguino project is an open-source PID controller with oodles of extras, using the Arduino framework. Feed-forward control of the heating element, pressure control via phase modulation of the vibe pump, fancy displays and controls, etc... also, Gaggia classics or coffees or whatevers don't have pressurestats. They have thermostats with

I sent you PM you can give me a call to help you trouble shoot more sometime if you like. I am not sure have versed you are with electric and multimeter usage, but someone who is could see if you have power to the pump when a brew button is selected. Be careful you check the

Jim, I have some, send me a PM and I can email one to you. Eric
