espresso making mags?

Water back flush every day the machine is used.
Detergent back flush once a month.

Never tried paper.

Anyone else notice that the quality of their shots diminish if they neglect back flushing?

I try and do it weekly, but often go about two weeks. Pulled a channeled mess yesterday, back flushed, today nearly perfect shot.

Maybe it depends on your water quality ? The water here is pretty good so I havent noticed a problem

All the white numbers on my 10+ yr old Capreso infinity grinder have worn off so i'm going to have to make more with a machinist's paint markerbut otherwise its been a pretty good grinder or maybe I shuld just buy a new one ?

edit: or don't worry about the numbers just turn the hopper to where it makes good gring

100% notice - which then reminds me I should be staying on top of maintenance instead of just reacting when the shot quality goes down - but then I get distracted by screen time and the cycle continues

What kind of savage doesn't backflush after every shot?!

only daily back flushes performed by a Druid virgin with Lourdes water will do

I use a huge bottomless portafilter for my morning latte. I have to reach above the stove for the stock portafilter and puck to backflush. I use detergent and do it weekly. If I go 10-12 plus days it starts to degrade.

Never thought to do a water only. I started dissolving the detergent before I put it in which is an improvement.

XXXer - I’d keep the grinder. I’ve got one on my bench to fix at the moment. If you’re happy with the coffee and it’s grinding I’d keep using it. Fucking expensive and finicky machines.

[bennymac]

I run a pulse of water through without the wand in place after each shot - but I don’t get out the back flush filter every time

yeah the capresso infinity seems like a good grinder, back when I did some field work at the research center one of the PHD candidates told me her uni bud had done the reasearch and made a spread sheet that came up with the capresso infinity as the best product, no point reinventing the wheel so cha-ching

Nasty spent grounds will come out every time you backflush after a shot. It takes an extra 20 seconds to slap on the blind basket portafilter and flush. If you don't have a spare/2nd portafilter handle for the blind basket, then sure, I might be lazy too.

It's less a factor of trying to keep this expensive piece of equipment in perfect shape and more a factor of not wanting to taint new shots with old grounds. Granted, my palate wouldn't know, but still...

I did a backflush on the perfectly clean machine after 1 shot this morning. The amount of grounds that came out was negligible. Didn’t go with my flow at all. Maybe after I’m done with the whole drink I’ll leave it on and do it before I stow it.

Running a wet paper towel up into the head needs to be a weekly task. That area where the portafilter lock meets the shower screen get pretty gnarly.

[bennymac]

We use one of these - a few back and forths with a pulse of water at the end and then a towel wipe - ready for next shot

Hadn't heard of this b4. But maybe its old news to youse:

**Coffee connoisseurs have long held the belief that adding a little water to the beans before grinding them could make a difference. A new study by researchers at the University of Oregon seems to confirm exactly why.**
Was a CNN article in KSL.

Yea, Tgapp has been preaching to spritz your coffee before grinding for years.

Yeah, I've never been able to notice a taste difference but it sure as hell helps keep static electricity at bay while I grind them.

Anybody have any experience with the Profitec Go?

ya spritzing your beans won't directly affect flavor, but it will affect retention, distribution, and clumping, all of which can directly contribute to poor extraction.

spritzing is more important for some grinders and in some climates (dry, high elevation places close to skiing being the most vulnerable to static-relatef issues), but it's beneficial enough that you should do it regardless.

I didn’t have luck with the spritzing. Seemed to make my high static grind and grinder grind to a halt. I do think the little needle stirrer has a working though. Better extraction since I started using it.

Oh, you poor guy. Once you make a good brew at home, it's REALLY hard to visit family or travel in general. Even most coffee shops are complete ass compared to my humble rookie setup. I can't imagine how a pro like you feels! Vibes, man.

James Hoffman did a good interview with the researcher of that study. A bit more approachable to listen to this than read the paper.

I think this is a solution searching for a problem.
Like are they just fucking around so they can say they saved .002 gram in dust and now it tastes like pineapple boothose instead of chocolatey tang.

More like it saves a fuck ton of static-y mess if you're single dosing.

The problem is observable. If there was no evidence of static charge in ground coffee, no one would waste their time proving the working assumption that spritzing the beans before grinding decreases the charge and results in better coffee.

meh, the savings were in the tenths of grams for the residential market.
I'll use my Baratza all week and there is maybe a teaspoon of grounds clinging to the machine. Use an enclosed hand grinder and it's a non issue.
