    Naked

    (Yes I do sometimes wander around the house naked but this is not the topic. )

    I bought a naked handle some time ago and from the other 3 handles this is the only I use. I just like it and the fact that I can fit a triple basked in it.
    One thing has been bothering me lately ... It is messy.

    It seems that it is splattering all over the place. At first I didn't notice and sort of wiped the mess from the back panel as I wipe the rest of the machine all the time. Yet I have been paying more attention as to how this happens and it seems that the little holes rather than dripping out in an orderly fashion, they spit in all directions. Surely if I use a normal handle I wouldn't even notice this.
    I tried different things, packing more, variations in grind, but both things alter the final result that ultimately is coffee and not cleanliness so I am sort of putting up with it.
    Has anyone noticed this and perhaps found a solution?
    Machine is a Commercial Carimal 2 handles

    Your replies are appreciated.

    Sounds like you might be getting some channeling. You should get a nice even extraction (ideally) where the coffee drips and forms over the entire pf/basket and then becomes a steady stream.

    Channeling occurs when you get a path through the puck that offers less resistance and coffee sort of 'explodes' out of the puck causing it to spray.

    Sounds like you have tried a few things with little success. Maybe try being particular about how you pack the basket. So tamp as evenly as possible. Try the Weiss Distribution Technique (or another distribution technique) to loosen some of the clumped grinds.
    It's all about getting a nice even puck so the water flows evenly through the coffee and gets a nice even extraction.

    I tend to agree Marc, I have a naked PF, it was a novelty at first, however I much prefer a standard PF.

    As you say, if you get it wrong with a naked you may well have a mess to clean up.

    I believe the original purpose of the NPF was as a learning tool, once you have your ducks in a row the idea was to revert to an enclosed basket setup.

    Are you saying that after going naked you must put clothes back on? Seems counterintuitive.
    So channelling mm I give it my best shot

    G'Day Marc,

    (Yes I do sometimes wander around the house naked.)

    Without pictures it doesn't happen.

    Agree with Yelta. I only use the bottomless portafilter for troubleshooting or dialing in some new gear.

    Once everything is sorted I go back to the spouted portafilter.

    Not to state the obvious, without using the NPF, the OP might not necessarily know he was having a problem. So it can be a catch-22.

    Are you guys using single or double spouts in these cases? (or does it depend on what type of cup/glass you are using)

    Not really, as long as he enjoys the coffee he is producing there is no problem, not everybody is anal about detail.

    A naked portafilter has no spout.

    Once I started using the "naked", I never went back to a spouted Group Handle.
    As a mainly espresso and black coffee drinker, you definitely appreciated nailing your shots and the "naked" most definitely helps with that. It's also cleaner.

    Didn't realise you were a "naked man" Mal, I agree, it's nice to "nail your shots"

    Not trying to stir the pot, would be interested to know what percentage you consider unsatisfactory? having a bit of an insight into your personality, I cant imagine it would be very high.

    My failure rate is pretty low, about the only time I make adjustments is when I start a newly roasted batch, and about half way through the batch as the beans start to age, usually takes about 3 or 4 shots to get it spot on with a new roast, even then the grinder only needs minor adjustment, the early shots are not undrinkable, usually a bit tight as I've wound the grinder down a notch or two to compensate for ageing beans.

    Once I find the sweet spot that's pretty well it for the batch, the goods shots continue until I need to roast again, about 14 days.

    At a guess, I would say I go through approx 8% of a roast fine tuning, after that it's plain sailing until the next roast.

    Perhaps I'm living in a fools paradise, or is it a case of ignorance is bliss.

    Hmmm...

    Maybe one out of fifty?
    Hard to say really as they are so few and far between.
    With dialling-in between roast batches, very rarely have to move the grind adjustment more than a couple of index graduations. There just isn't much in it to be honest... The shots before adjustment are still pretty darn nice.

    Failure rate for me is zero ... when it's not right, there must be a problem with the beans.

    OK ... I hear what you all say. Training tool, you are probably right but since it is cool, I can use it all the time. Furthermore I can use a double basket in it, and a triple basket ... no limitations ... bottomless.
    Double spout on a naked handle ... not impossible but it wouldn't be completely naked, more like a fig leaf on a naked handle.

    Back to my little splashing problem ... (no not that one, come on!)

    I have been paying more attention to the grind and the packing of the ... what'sisname? ... puck ... and yes, I get it. The finer the grind, the higher the pressure and the slower the water flows, the same with packing the grind. However I still notice although less ... that there is a main stream of golden coffee flowing nice and thick out of the basket but occasionally some of the holes on the outer rim seem to get a mind of their own and spray away from the center in a random fascion. Some sort of sabotage happening ... see if I can remember to make a short video of my inimical coffee behaviour. .

    PS ... how do you pack the coffee? Do you give the doser a few bang, press and then give a bit more, or do you fill the basket and then press in one go? My doser needs 5 lever turns to fill a double basket. I then press it down in one go. I wonder if doing it in stages and press at each stage will make a difference? Too much fiddling?

    The real reason I like the naked handle is because my machine groups are rather low and I like to use behemoth cups that need wiggling out from under the spouts.

    1) Naked p/fs show you exactly what the pour is doing
    2) Preserving the crema is improved by not bouncing through extra havoc.
    3) Using a single spout instead of a naked seems crazy to me - a naked gives a less "flow intrusive" result.

    Only the first of those may be considered as a training tool, and only then if you believe the learning curve ends at the first good shot. Needless to say, I cannot agree that a naked is a mere training tool.

    I guess I am with Mal on this one. I haven't used a spout at home for years, and cannot see why I would.

    I find naked also far less messy. Once shot is pulled and finished, there are no drips etc between pulling out the PF and banging out the puck etc.

    Cheers

    Hi Marc
    is your tamper a good fit?
    if you're getting spraying/ channelling around the edges, could it be that the edge of the puck isn't compacted?
    you might notice a good pour with a naked pf begins around the edges, moving into the middle.

    therefore, if you aren't tamping the edges well, it'll channel there.
