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!

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).

I'm relatively new to the espresso game and my espresso always tastes a bit sour... please help! I'm using a Breville Barista Express. From what I understand, the sourness is generally because of under extraction. The water seems to be at around 190-200 degrees, so I don't think that's the issue. I've tried to dial in the grind size so that pulling a shot takes around 25-30 seconds. At that grind size, the pressure gauge is at the very top of the range. I believe if I go finer with the grind, then it'll take longer to brew and push the pressure up higher. I'm not sure exactly what to do to address this. Could it be that I'm tamping too hard? I push relatively firm, aiming for about 30 lbs of pressure. Thanks for the help!

How many grams of espresso are coming out at the other end? The rule of thumb is around 2x the mass of coffee in the portafilter. However, that's just a rough guide. Generally, more water -> more extraction -> less sour. Just for experimentation's sake, try adjusting variables like fineness or water, and let the shot time go longer. See how you like the results.

I tried to follow all the rules of espresso. "Only X seconds of brew time", "Only this Y grams of water". I never got a good tasting shot. Then I started experimenting. I have a pretty cheap DeLonghi Dedica, and I began to tailor my shots to how my machine actually works, vs how others told me to do it.

Nowadays, I pull a ~43g shot from 18g of coffee. I have my grinder set to some fineness level that I haven't needed to adjust in months. The shots I pull are always better than most non-specialty coffee shops. Sometimes, I even get a perfect shot that tastes like heaven. It all became better when I stopped focusing on rules and started learning what my machine likes.

Love this comment. I like the mindset of using the rules as general guidelines, but experiment a bit and see the impact.

[–] [email protected] 2 points 1 year ago

You just encapsulated the concept of espresso I thought was long lost: Espresso is an art.

[–] scorchingheat 3 points 1 year ago* (last edited 1 year ago) (1 children)

I highly recommend a scale (with 0.1g precision) to weigh how much coffee goes in vs how much liquid comes out. Without it you're just going to be eyeballing and that will quickly become frustrating (I've been there). No need to spend a lot of money, a cheap €20 one will get you a long way.

Once you get a scale, you can follow this simple recipe:

  1. grind 18g of coffee (weigh the grounds, do not weigh the beans unless you have a very good grinder with low/no retention)
  2. Extract your espresso for 30 seconds
  3. Weigh the liquid in the cup, it should be around 36g (1:2 ratio). If it's under 36g you're grinding too fine, if it's over then you're grinding too coarse.
  4. Repeat until you consistently get it right.

After it's dialed in, you can start making micro-adjustments to your liking.

[–] hi_its_me 1 points 1 year ago

Thanks. I actually have a .01g scale, but I was only weighing what went in. I didn't realize I can also weigh the output to help tune in. Thanks for the instructions. Seems pretty clear.

[–] [email protected] 2 points 1 year ago* (last edited 1 year ago)

The BBE has a lower grinder burr that is not documented in any of the papers that come with the machine. Discovering this and adjusting it was a game changer. I'll try to find that video.

Edit: this isn't the video I used, but it seems pretty thorough https://www.youtube.com/watch?v=QNvOcE4-VEo

[–] not_woody_shaw 2 points 1 year ago (1 children)

If it's under extracted then extract more. If you let it run a few seconds longer you'll get more extraction along with a larger, weaker shot with less body, but at least if the level of sourness is right you'll know more about what's going on.

Does your machine have a preinfusion option? Preinfusion can increase contact time, and thus extraction, without increasing shot volume.

[–] hi_its_me 1 points 1 year ago (1 children)

Makes total sense! I don't think it has an (obvious) pre-infusion option, but I'll do some research to find out.

[–] not_woody_shaw 2 points 1 year ago

Before I upgraded the electronics on my Gaggia Classic, I used to do a "poor man's preinfusion" by leaving the steam valve open for the first few seconds of the shot, so that most of the water could escape that way instead.of thru the puck. Not sure if the same would work on your machine.

[–] kyle1320 2 points 1 year ago (1 children)

In addition to measuring your output / a longer extraction, you can try a longer pre-infusion, or bumping up the temperature. 190F is on the very low end of what is usually considered ideal -- you could try aiming for 195 - 205. Also, if the portafilter is not fully heated that will offset the brew temperature and cause lower extraction.

[–] hi_its_me 1 points 1 year ago

Thanks. I'll read up on pre-infusion. I also didn't know I was supposed to be heating the portafilter.
