After working on a bicycle or an engine, hands covered in grease, I can confirm that coffee does the job. Spent coffee grounds are gritty like sand so they work amazingly well to get the grease off. I use a bar of soap at the same time which causes coffee grounds to get embedded in the bar. It’s a good thing too because it always helps to have the soap bar a bit gritty.

That much is proven for me.. been using coffee for years to wash greasy hands instead of buying the special purpose heavy-duty hand cleaners.

Coffee is now being used to make clothing and one of the claims is that it gives odor control. I’ve cut back to showering once per WEEK (a pandemic side-effect that became a habit). Even though I’m back to leaving the house regularly the shower habit did not change. So my armpits get quite rank after a week. 💡 If coffee grounds have a deodorizing effect, why not use them on arm pits? I’ve not heard of anyone doing this but thought it’d be worth a test.

So I brought spent coffee grounds into the shower and after one scrubbing with them my armpit odor was gone. Coffee grounds work better than shower gel. Normally I scrub with shower gel, rinse, & sniff. The first iteration is usually not enough.. I have to repeat that process 2 or 3 times with shower gel to get the stink off. Coffee grounds worked on just one iteration. I think what happens is the deodorant is sticky & waxy which then gets coated with sweat then the sweat-loving bacteria. The abrasive grit from the coffee grounds scrapes the sticky waxy nasties away faster than soap can dissolve it.

Coffee seems to work on its own but I only did this experiment once so far so I followed with shower gel anyway for good measure.

Of course arm pits aren’t the only area that stinks after a week. The groin doesn’t smell too good either. What develops to maturity is what’s called cock cheese¹. I’m not flexible enough to do a proper scientific test. The nose-crotch proximity is what it is. It stunk before the coffee treatment but not after. So it worked at least to the extent that I could confirm. I guess my next partner will have the noble scientific task of assisting with the close proximity sniff test mid-shower and indicate whether shower gel is still needed.

footnotes:

  1. Sorry folks. Indeed it’s not the most elegant nomenclature. IMO there’s a language deficiency here. That’s the only name the stuff has AFAIK. Be sure to forget that term whenever you’re eating cheese. Or alternatively it may not be a bad idea to just cut cheese out of your diet at this point.¯\_(ツ)_/¯ You were warned.

FYI, coffee grounds are terrible for your plumbing, and can cause serious blockage in your sewer line.

I’ve heard that argued both ways. Some people claim it cleans the lines. But my instincts are to agree with you. If the coffee ground gets greasy that would seem to give it a chance to stick in the pipe or simply stick to existing grease. OTOH, grease in the pipes can be melted by pouring boiling water down.

Since coffee is great for compost, the bulk of my coffee goes to the plants or to the compost. But I’m still keen to clean with it. Not much is needed for cleaning. 2 pinches is enough for one arm pit, or two hands. Some coffee grounds stick to my filter after shaking the bulk of it into a plant so I end up rinsing those down the drain as well.

You can't pour enough boiling water down a line to make a meaningful difference in cleaning your drain.

I had an extremely slow kitchen drain recently where a liter of water took a couple hours to drain. Every week I poured boiling water into the drain pipe that came out of the wall (bypassing the trap), waited ~30-60 min for the temp to drop a bit before giving a dose of enzyme-based cleaner so the enzymes had a warm start and could chow down on whatever was in there. After a month or so there was no noticeable progress. Snaked it. The snake made it all the way to the main pipe but strangely did not clear it. So I poured in ½ liter of sulfuric acid and let that sit for hours. Still not clear. Then I plunged the line with the acid in it using the kind of plunger that attached directly to the pipe. That cleared it. I have no idea what the clog was.

Now I run the dishwasher on the highest temp as a preventative measure. The lowest temp (50°C) is good enough for the dishes but I figure the highest temp (70°C) will help maintain my crappy kitchen drain pipes. It’s unclear to me if I’m wasting energy or being sensible. IIUC, the 70°C temp setting is for pans (which the dishwasher maker expects to be greasy). The clog that I cleared was from the previous tenant (a young student, probably careless and not knowledgeable about drains). The only grease or oil I put down the drain is residual after a bulk of it goes to the compost.

That’s the only name the stuff has AFAIK.

The medical term is smegma.

Strong, potent coffee news for strong, potent coffee lovers.

Hoping to mirror the great community of r/espresso.

We are a kind and accepting community for those who love, want to love, are getting into, or are interested in espresso and espresso accessories.

Rules

I didn't think we needed this section on Lemmy, but...

Resources

Here is the main resource from the same sub, since it's amazing.

If any of the original mods, or anyone else who loves espresso, would like to take control or help mod, please let me know. I'd be as happy to help as to pass the reigns.

A gracious community member has added some of the resources from the Reddit sub.

Espresso Aficionados - Wiki (as of May 2023, this is the most up-to-date resource for machine recommendations and it has a bunch of detailed guides for how to dial in espresso, puck prep & troubleshooting, and more advanced techniques!)

Espresso 101 Espresso starts with the coffee bean. Fresher is better. As u/Beans_McGhee says, "The beans really need to be roasted within the month you use them for perfect espresso." Store-bought beans are fine, really—but part of the "fun" of espresso is trying different beans.

You grind your coffee beans using a grinder. This sub has lots of opinions on grinders.

The amount of ground coffee you use is called the dose. So when u/SingularLattice says, "Make sure you have the right dose for your basket", that's what he means.

A basket is the little metal cup that goes in your portafilter—that's the metal thing with a handle on it. Espresso machines often come with 4 baskets: a single and a double in both unpressurized and pressurized. Doubles are the larger ones; pressurized variants are a different shape and may say "dual wall" on the bottom.

You would use dual-wall if you are using pre-ground coffee. Almost everyone will make ("pull") double shots—when you get into weights and times, it's all based on a double. So you should likely use the unpressurized (single wall) double basket.

Advanced practitioners will dose by weight. Typically, you'd want ~7g for a single shot and ~18g for a double shot. Automatic grinders may dose by time: this will get you "close enough". Thus, the "single" dose will be around 7g and the "double" will be around 18g. (You can fine-tune these amounts—more on that later.)

Coffee grounds are light and fluffy, but you want them to be compact for espresso, so you tamp them (with your tamper). Advanced practitioners will calibrate their tamping pressure (e.g., with spring-loaded tampers)—don't worry about that. Just give it a reasonable amount of force. If you're putting your whole body weight on your tamper, that's too much.

You will get a feel for the right amount of force. You can also look at the level of the grounds in the basket. Use shape of your tamper or other tool to estimate how much space should be between your (tamped) grounds and the top of the basket.

As u/SingularLattice says, "You need to tamp FLAT, not hard. So long as it’s firm, you’re good."

At the advanced level, preparing espresso is all about ratios, namely weight and time. Generally, you want a 2:1 ratio in about 30 seconds. The 2:1 ratio means the ratio of your dose (i.e., ~18g) to the resulting espresso (i.e., ~36g). The process of brewing espresso is called extraction.

Many espresso machines will do this for you! When you press the double shot button, it will dispense enough water to make the "right" amount of espresso... presuming you're using the right basket and the right dose! With such machines (e.g., the Breville Barista Express, or BBE), what you should do is watch the pressure gauge. It should be in the "espresso range". (Advanced practitioners will measure pressure in bars—you want ~9 bars in an ideal world.)

If the pressure is low, you either need more grounds (higher dose)—which you can get by adjusting the grind amount—or a finer grind—which you can get by adjusting grind size. You may also need to tamp harder, but typically this isn't the problem.

(If your pressure is too high, the inverse is true... but this doesn't happen very often.)

Every bean is different, and so needs different settings to produce a good result—in your case, to keep that pressure dial where you want it. The process of adjusting these different settings is called dialing in.

Your goal here is a well-extracted shot. That's all about how it tastes! Espresso should be sweet and balanced. If it's sour, it's under-extracted (to which you would grind more and/or finer); if it's bitter or astringent, it's over-extracted (to which you would do the opposite).

Everyone here is adjusting all these variables (bean, pressure, grind size, dose, ratio, extraction time, and more) in search of the perfect shot!

(Derived from this post by u/basseq.)

What espresso machine should I buy? Great question, and a very common one. Generally, there are two key inputs:

How much do you want to “tinker” with your espresso? Do you want to play with different variables, or just wake up to a good coffee?

How much do you want to spend?

Espresso can be a very expensive hobby, so the answer to the second question can you get to the best bang for your buck.

Remember that espresso is not just the machine. The other notable expense is the grinder, which can be as much as—if not more expensive—than the machine itself. There’s also some key accessories (notably a scale) and the cost of good coffee itself ($15+/lb).

Recommendations by Budget <$500 – Bare Bones If you’re looking to step up from a Nespresso or just drink less Starbucks, start here. There are really two ways to go:

Manual ($250–$300) – Flair Neo ($125) + 1Zpresso JX ($130).

Automatic ($450–$500) – Breville Bambino ($350) + Baratza Encore ($170).

The DeLonghi Dedica ($350) is also a solid choice. For grinders, you can also check out the Breville Dose Control ($150), or upgrade to the 1Zpresso J-Max ($230). The Sette 30 ($300) and Mignon Notte ($320) grinders are solid, but may put you above $500.

If you’re really looking to do espresso on the cheap, forego the grinder and work with pressurized portafilters on the Neo or Bambino. Many of us started with things like the DeLonghi EC155 ($100), but it’s hard to recommend.

Keep in mind that the espresso you get in a cafe was ground on a grinder that cost around $2000 and brewed on a machine that cost at least $15,000. You can't shrink all of that into a sub $300 setup without a huge loss of quality. –u/MyCatsNameIsBernie

$500–900 – Entry Level If you think you’re “serious” about espresso, this may be a better entry point than above, which you might outgrow sooner than later. There are two common choices here:

All-In-One – Breville Barista Express ($750) or Pro ($850). While the community sees the built-in grinder as the weak spot (no upgrade path), and long-term reliability can be spotty, it an easy and popular entry point into the prosumer market.

Separate Setup ($800–900) – Gaggia Classic Pro ($500) + Baratza Sette 270 ($400) – The Gaggia is a classic and time-tested, with lots of options in the used market.

Something like a Bambino Plus ($500) or Lelit Anna ($570) might also work. There are a lot of good grinders in this range: the DF64 ($400), Eureka Mignon Silenzio ($470), Baratza Vario ($480), and Rancilio Rocky ($430) are all well-regarded.

If you’re strapped for cash, the r/espresso guidance is to prioritize the grinder. Better to run a cheaper machine (Bambino/Dedica) with a nicer grinder than the other way around.

$900–$1,500 – The Standard The endgame for many people, this range is probably the “sweet spot” for great espresso without going over the deep-end.

The r/espresso Standard – Rancilio Silvia ($850) + Niche Zero ($680) – The Silvia is a classic, moddable, and can be found used. For this price range, the alternate choice might be something like a Lelit Glenda ($900), or pairing a Gaggia with a nicer grinder. For grinders, ECM and Profitec both have offerings ($550), Baratza Vario W+ ($600), Eureka Mignon Specialita ($700), or any of the ones in the previous category. You can start mixing and matching machines and features and specs.

$1,500–3,000 – Prosumer We’re getting heavily into the “prosumer” market now, and there are less common machine+grinder pairings, so we’ll start looking at them separately.

Machines – Profitec Pro ($1,800), ECM Classika ($1,600), Lelit Elizabeth ($1,700), Rocket Appartamento ($1,700). The land of shiny chrome and lots of knobs. The Breville Dual Boiler ($1,600) is in this range too.

Grinders – Mazzer Mini ($800), Mahlkonig X54 ($750), Eureka Oro ($800).

$3,000+ – Dream Machines From here, it’s dream machine land and the art of the possible. If you’re asking, “What should I buy,” you probably shouldn’t start here.

Machines – Lelit Bianca ($2,900), ECM Synchronika ($3,200), Decent DE1 ($3,500), plus some offerings from Isomac, Rocket, Elektra, or Nuova Simonelli. You get into true “endgame” machines like La Marzocco Linea Mini ($5,900) or Slayer Single Group ($10,000).

Grinders – Eureka Atom 75 ($1,400), Mahlkonig E65S ($2,300), KafaTek Monolith Flat ($2,500), Weber EG-1 ($3,700).
