The espresso double shot recipe I always see passed around is 14 g grounds to make a 2 fl oz (60 ml) shot. But the water ratio ought to be 1:2, right? Isn't that recipe over twice as long as it should be?

1:2 ratio is based on weight.

14g grounds > 28g espresso (or more often now it’s 18g:36g or 20g:40g)

Yeah, I do everything by weight and I've been doing just that, 14g > 28g espresso.

The "2 fl oz" passed around is 60 g so that seems just insanely off the mark.

Article from the SCA about this. The recipe you quote comes from the “heritage” definition of espresso:

quote:

Before exploring the results of the study, it is essential to have a frame of reference. Below is the heritage Specialty Coffee Association of America (SCAA) definition of espresso:

“Espresso is a 25–35ml (.85–1.2 ounce [×2 for double]) beverage prepared from 7–9 grams (14–18 grams for a double) of coffee through which clean water of 195°–205°F (90.5°–96.1°C) has been forced at 9–10 atmospheres of pressure, and where the grind of the coffee is such that the brew time is 20–30 seconds. While brewing, the flow of espresso will appear to have the viscosity of warm honey and the resulting beverage will exhibit a thick, dark golden crema. Espresso should be prepared specifically for and immediately served to its intended consumer.”

They surveyed baristas, most of whom were pulling 1:2:

quote:

An overwhelming 93% of respondents considered the espresso they pull to be a double shot. In subsequent discussions about the results at a recent Barista Camp in the US interesting conversations about this terminology emerged: several baristas noted that single/double measures are no longer valid and a number of respondents refer to any espresso extraction as a shot, no matter the volume or mass.



The majority of respondents reported their lowest dose as 18 grams and their highest at 20 grams. This was consistent with the amount of the “average dose”: 66% reported this amount to be between 18 and 20 grams.



An overwhelming 82% used weight to measure espresso yield. Measured by weight, the average output for espresso extraction was 36.5 grams. For those measuring by volume, the average output was 1.8 ounces or 74.2 milliliters. Addressing ratio: for every gram of input espresso grounds, how many grams of output beverage are obtained? The average response was 1:2, for example, 20 grams in and 40 grams out. All responses ranged from 1:1.5–1:2.5.

So you’re seeing a difference between the “heritage” recipe and the common recipe used in the industry.

That's not correct, usually it's 18g in and 40g out roughly for a double. Notice they're both weight measurements, it's likely the specific gravity of espresso is not meaningfully different from water but just use grams IMO.

e;fb

The volume difference is due to the bubbles in the crema I'd expect. The specific gravity of espresso isn't really meaningfully different to water and 1g would be =1mL if it weren't for the additional volume of air. It's still a little different, but at this size it's more a rounding error.

Pre-ground is objectively worse than using a capresso infinity or encore at the time of brewing (non espresso). You can easily modify the infinity making it stepless, I've been using the same small area of adjustment for years with my v60. You won't be using a wide range of grind settings for drip/pour over anyway.

http://lowendespresso.blogspot.com/2009/04/modifying-capresso-infinity-for.html

Hmm, that's an interesting situation. The v60 is the second most grind sensitive brewing method I can think of after espresso because the bottom hole is so drat big. Minute changes in grind will have large swings in extraction.

I've never seen grind distribution data for an encore but here is something for the Baratza Sette(3x the price, same mfg):

and a link to the source: https://www.instagram.com/p/BSKYHLEDuL_/

"Pre-ground is objectively worse than..."

To clarify my statement a bit, I'll assert that preground coffee less than a week old on a high quality commercial grinder will taste noticeably better in most immersion style brewers. The v60 has to be dialed in very tightly for the coffee to really shine, so I'm not sure you'd be able to do that UNLESS you have a cafe near you that offers pour-overs from a v60. Then you could just have the coffee ground to whatever they are doing and test my assertion.

On another topic, has anyone done this before: https://leaderboard.coffee/en-us ?

they haven't put them up online to confirm what's what but i am drinking a coffee that looks washed but smelled more like thyme and oregano than anything i've ever tried before and now is really intensely like rose/violet in the cup. truly no idea what it might be, clearly went through some aggressive/nonstandard fermentation process though

Gather round, one and all, and thrill to my turgid tales of underwhelming misadventure!

I was too excited to take pictures of the shot I pulled but I think it was pretty alright!

I have my Baratza Vario W set to the factory "contact" point of 2Q. Just assuming that espresso would require a very fine grind, I tried to initially set the grinder go 1K (or whatever the midpoint of the fine adjustment is). I set the grind weight to 17 grams and started it. I guess either the grind size was too fine or something wasn't flowing because at 1x it was grinding either a very small fraction of a gram per second or nothing at all. The scale was not moving while the grinder spun. I stepped the grind size up to 2K and it started grinding, but it was still extremely slow. Eventually it seemed like whatever contents were between the burrs made it out and it eventually stopped grinding at 16.7 or so grams. The annoyance with the Vario W is that it will tend to stop grinding once the weight reaches about 0.3 grams less than the set amount. If you're a real nerd you can tap the "start" button a few times and it will eventually reach that round number, but it probably doesn't matter.

Followed James Hoffman's early recipe of 17 grams of grounds, and measured 60 grams into the basket. Tried to do a pre infusion so light pressure until I started seeing a few drops into my cup. Waited maybe 10 seconds, and then pulled with what I thought was high pressure, but I think I only hit 6 bar on the gauge. I failed to measure how many grams of espresso I got out. I'll try to next time.

The texture was thick, a little tart, but not extremely sour. Maybe extraction could be better, or I could apply more pressure. Honestly not bad for a first try. Unfortunately I'm now almost totally out of beans, so I need to go buy more.

Don’t worry about measuring the amount of water in the basket…just fill it until it’s 5-8mm from the top.

This will affect a few things:


1) you’ll need a spare cup for the remaining water after you pull the shot

2) you won’t have to tamp as hard or potentially grind as fine since the extra water will create more pressure on its own.

Awesome. I can't offer much advice as I don't have mine yet, but I plan to use the orphan espresso prep system. Seems reasonably priced and a good way to remove some variables.

Second shot I've pulled with the robot. I did go ahead and buy the orphan espresso little system for it. This time I remembered to use both the top and bottom paper filter. It has a little less mouth feel, maybe?

Still tart or fruity. This was with a Tanzania peaberry roasted at Central Market with they claim a fairly light roast.

I put in ~17g coffee, 60g water into the basket, and pulled ~43.5g of espresso. I forgot to look at the little timer on my hario scale to see how long that took. Doesn't matter. I turned this one into an Americano to have with an almond croissant.

How old are the beans and are you preheating the piston?

I’ve heard you generally want 1-2 weeks after the roast date to hit the sweet spot for grinding and brewing. On my coffee it’s definitely a little rough if I use it 4/5 days after roasting but gets better after that time.

I do darker roasts so I don’t bother preheating most the time, but I’ve heard it can be worthwhile on lighter roasts. I’ll usually just do it if it’s early in the morning and the house is cold. I bought a silicon 58mm flush disc off Amazon like this:

Backflush Disc – Blind Insert for Espresso Machine – Food-Grade Silicone – 3 Size Variations – Compatible with Cleaning Tablets and Powder – Wide Compatibility – (58mm) https://a.co/d/hidPnNn

You can also just put boiling water in a cup and submerge the piston in it for 30 seconds if you want to give it a try.

The price of the Harios are not very high, so it might be a good option.

Since you already have a nice electric grinder, you could go for a nice espresso level hand grinder? Or if you can afford it a nice single dose electric grinder!

On another note, I decided to try some place other than sweet marias.. ordered 5lbs each of a Rwanda and Ugandan from happy mug in preparation for my kaffelogic and robot.

Before diving into another grinder you can try getting the pressurized basket and seeing the difference. The other basket will allow for you to grind a bit coarser so you won't necessarily need an espresso level grinder

Yeah it’s real easy to get the right texture with a steam wand. The nanofoamer does a decent job of making foam, but it doesn’t seem to be as easy to get decent microfoam from one of those things compared to what I can do with my steam wand.
