It's hard to give very exact advice on where to go with this coffee, I was just basing my recommendations on the video and your description that it was on the brighter side. 10 sec preinfusion sounds good. I still would maybe grind finer and in turn extend both the pre-infusion and brewing phases a ...

Flow-rate seems too fast in the video. From the first drops in the cup until you finish the shot is only about 20 seconds. Like Rocky I think your grind should be tighter. But of course, your taste and how you like the shots is what matters most. If you get clumpy grounds and/or you think distributi...

wdt = weiss distribution technique, "Improve your Espresso with Weiss Distribution Technique". Basically the aim is to stir the grounds to break up any clumps and to distribute the coffee evenly in the portafilter. I think most people use a funnel of some sort to avoid spilling grounds while pouring...

I'm guessing it's because your coffee is stale and/or your grinder not being consistent enough and/or poor puck preparation. These big bags of italian coffees sold in supermarkets can be many months old. Try some fresh (1-3 weeks old) beans and see if that works better. If it was because of the port...

Looking forward to hearing your thoughts on it too. I was lucky enough to take delivery of a new idro-matic speedster at the end of may. Had never used one before so have no idea how it compares to stock machines but I'm thrilled with it,how it performs and the options at hand for preinfusion.Though...

Are the grounds actually getting coarser or could it be that the adjustment dial just isn't fastened tight enough to the screw? I would suspect the dial could drift when the grinder is running if the two hex-screws aren't tightened. If the adjustment screw is moving and your ground coffee is getting...

That's a nice slow drop in pressure already so then I'm not sure this extra ppic will have much effect at the end of a shot when disengaging the pump. Like you said earlier it's unfortunate it can't be removed from the process, so you won't be able to compare with and without it on the same machine,...

Thanks for descriptions and details John. It does complicate the group and personally I'm not sure how I feel about the looks of it yet (just based on pictures). This and the fact it's such a recent option and no user experiences anywhere made me unsure before putting in an order a while ago. Even t...

Early backer here too, although not among the first few. Haven't gotten an e-mail confirming shipping or tracking number but got the package today, so it might be they had some issues with their systems and maybe everyone won't receive an e-mail about shipping. I also went for the red one. All parts...

Very interested in improving airflow in my quest roaster and you guys have convinced me, I'm going to contact Molly to buy this new type of drum for it. Have any of you also cut the resistor to the fan so you get the full range of speeds on it? (A mod described by someone with pics and all
