I did molykote the timing belt, as suggested. It's been a quieter (more than a little bit, but not dramatic) when the motor speeds up for the purge; and it stayed that way for the past few weeks. Don't know if it's permanent, or if the lube will need to be repeated

Ok, so I'm probably still not coarse enough. Honestly, there are literally dozens of photos online all showing different coarseness. But if I understand well, one specific grind size is an impossibility to say with a moka pot because different coffees and different extractions and different personal tastes will mean different coarseness. Won't it? Anyway, "let it flow without timing

Tim - what technique are you using to brew? I do a lot of flash chilled pour over in the summer, but haven't ever really done cold brew

I recommend asking for clarification from Clive Coffee on their policy. If it's not documented, it should be. It's my general understanding that the sender has to show proof of delivery. Personally, if something wasn't delivered and the seller refused to help, I'd file a non-delivery claim with the credit card company. Unless the seller has a waiver buried

Just fixed it lmao. I took the hose and pulled the breaker and the o-ring was almost completely disintegrated. Cleaned the valve and put a new 007 ring on and fired up, seems good to go. Also notice no more air bubbles from the steam line. Also notice steam wand is a lot stronger now, I don't really steam

That looks like you're overextracting and maybe not stopping extraction soon enough. I would grind coarser. You also should be able to let it flow without timing it, and yes, you can turn down the heat near the end but be sure to completely stop the brew before it is bubbling out the chimney

I don't know anything about white coffee, but if that's the answer then what's with the orange color? Is this one of those "is the dress blue and black or white and gold" things?

I do this more with wine than with coffee, but I'll take the same approach. As it's brewing it has all the aromatics I love,.. warm, hazelnut, dark chocolate. But when we taste, though it's lovely and not actually that bad at all, there is a tannic dryness. I don't get bitter or sour but a bit of an astringent

The BDB vacuum breaker (anti-vac valve) is extraordinarily high quality piece...All stainless and PTFE. It seems to stick less often than most AVVs from other machines. But it can happen. It happened to me once years and years ago before I knew what they were. In most cases a sharp (but no hard) rap with something hard, taps is loose

If one is not a metrologist, the 'fiction' can be close enough to the truth. Once one has their machine under their fingers and is primarily interested in making fine espresso, knowing the exact group temperature is irrelevant. Either the espresso is stellar or it ain't. Make changes if it ain't. Don't get caught up in measuring more
