Hey all, I recently purchased a Cherub off the forum. Its in great condition and no issues with the machine itself. It had an aftermarket Bottomless/naked PF with it which ive been using to gauge flow etc. The coffee when using this with either the 15g VST basket or Espresso parts HQ double basket seems to just spray coffee in multiple places, but at the same time I am also getting a nice flow which is centralised through the basket, just with some spraying dotted around the edges of the basket. So........im quite confident that my process is pretty good, I use fresh beans, weigh in and weigh out, a distribution tool and a good firm tamp creating a nice (near perfect) level in the basket, and when pouring, the flow does centralise from the initial pour and creates a genuinely great shot with crema, however, the side and edge of the cup as well as the machine also get sprayed. So, my question, is this the aftermarket PF not matching the baskets very well, or should I be looking at something else. Thank you
Greetings, hopefully my investigations will help others. You know the feeling, you have your routine off pat, you are consistent. Nearly every shot pours nicely. Then a mate comes round, you make him a coffee, all good. You make yourself one, and end up with a pebble dashed cup, coffee machine, kitchen worktop. I actually said to him "this only happens when you're here" Which got me thinking. It really did only happen when he was there. I make an espresso before I go to work. I make an espresso when I get back. I make an espresso after dinner. Hardly ever spray. Each time, I make AN espresso. But when I make two in a row, the second one spurts.:coffee: What's the difference? Well in the case of my machine, the difference was the sound the first shot made, when I switch on the pump. It's quite loud at first, then quietens down. The second shot is quieter. OK, I'm drawing it out. For the first shot the system isn't fully pressurised. The shot pressure ramps up, the pump quietens and I get a nice shot. Second time, it's pressurised from the start, I guess the puck fractures as it's hit by full pressure,and I get spray. The solution is to crack open the steam valve before a shot, release the pressure and start from scratch. Bingo! I know others pressure profile using the steam wand, and I guess that's sort of what I am doing, but really, it's a cracked puck anti spray procedure. I'd be interested if anyone else finds the same.:coffee:
After reading plenty of posts, watching plenty of instructional videos and over a good dozen attempts at using a naked portafilter, I'm still struggling to avoid coffee spraying everywhere. Now I'm assuming it's down to a combination of the grid (using a 'hacked' delonghi), tamping, and the amount of coffee causing it. But is there a method to the madness that I'm missing? Any help is appreciated.
Evening chaps, I could do with a bit of advice. Got a classic paired with a Super Jolly. After a good few months with the grinder, my shots are OK. If I'm being critical they are a tad sour. In my infinite wisdom, I have got myself a bottomless portafilter, to see if this helps... hmmm Now I see to have other problems. I'm getting spraying from the basket [standard gaggia double]. Reading the forum it seems to be channeling. Also the crema's are nicely dark, but have a few big bubbles in. I never got this with the standard basket and twin spout. I can't get the rat's tail, more like a rat's ass hole! I get 2 or 4 streams, and a kind of a dead spot in the centre. If channeling is the issue, is there anything I can do to stop it? I'm tempted to try a VST, but will be disappointed if it's not the problem... I suspect it's my technique. I have scales, and I'm getting 18g in and around 36g out, trying to aim for around 25 seconds. Coffee this week is Rave's Suarez. Tamper is Knock Heft. Cheers
