Electrical current might be the key to a better cup of coffee
- Thread starter JournalBot
- Start date
I don't speak the King's English, but I was always under the impression "cuppa" referred exclusively to tea. Can it refer to tea and not tea? Arthur Dent asking.

The static charge generated during a grind is also responsible for the small mess you make when pouring the ground-up beans into your coffee brewer. The grounds just stick to any surrounding surface. Putting a few drops of water into the grinder before grinding reduces that mess somewhat.

How many science disciplines did this guy consult, lol. Must be some serious professors with their coffee.

Now the real question is how long until James Hoffman tries making coffee with this new method....

Jennifer, for a brief moment, you had made my day beautiful with that headline: "Electrical current might be the key to a better cup of coffee". I thought I had the perfect excuse to don the white lab coat, hire the Igor, strap the coffee maker to the slab, raise it to the heavens while lightning arced overhead, bolts raining down from the sky, to hit the rod and electrify the brew, as it rises from the slab and stumbles forth to awaken the townspeople while I laugh manically, liquid inspiration held in one tiny, perfect cup!
But it turned out to be the opposite. Ah, well, this is good to know, too.

In the United States, a "cuppa joe" is coffee (esp. cheap diner coffee, but not exclusively).

In the United States that would be "cup of joe" or hyphenated "cup o' joe". The English expression has similar root but sounds different as "cuppa". I don't know the right pronunciation terms but the English expression flows faster and the "cup o' joe" has a longer and more seperated "p" and "o" sound.

Tea only. And frankly anyone suggesting otherwise is close to inviting us to come back and take back over.

I’d like to see this measurement applied to steamed water. (Yes, you read that right.)

I give my beans a couple quick spritzes with an atomizer when I weigh them, works great, no fuss.

ETA: When I filter by "American English" it turns out "Cuppa Joe" is more popular than ever, but I think that's because in title case it's the name of at least one coffee shop.

I feel like it's more like "I'll have a cup-a-joe" to allow the words to slide together rather than the way the British use "cuppa".
Also I swear I hear things like "I'm a mess until I've had my morning cuppa" a lot more these days from the British shows I've watched so I don't know if that's driving more usage in the US? Although, from the graph above it appears that this trend may have already peaked in relation to Joe.

You might not be my first choice to take us by hostile acquisition but any port in a storm, right?

I just let the grounds sit in the grinder while the water is heating. The charge dissipates.

Unlike 1812, this time the British don't even need to set fire to the White House because its current occupant is tearing it down for them.

Is it "take back over" or "liberate"? given current US management I'm tempted to view the later. Heck even a tool like Farage seems refreshing compared to Stephan Miller or Trump.

Don't promise us salvation form insanity and fascism and then leave us hanging...
If all we have to do is yell cuppa cuppa about coffee to get some help - I'll get started
Even with the mess of Brexit and your own brand of Trumpians, you still seem do be doing quite a bit better.

Since we seem to live in a world where the worst possible outcomes are inevitable,
Judging coffee by its electrical conductivity might lead to adulteration with salt.

At least in the mid Atlantic, it is pronounced "cup a joe", not with an oh sound in the middle. If that is said.
Pretty much everyone (around these parts) calls it "coffee"*. Not cup of coffee, just coffee. Assuming they mean the actual basic beverage. 98% of people are ordering a "latte". Or "mocha" or "macchiato". "espresso" "cafe americano".
Very few people order just "coffee", but when they do in the mid Atlantic, it is almost always just "coffee".
There is more of a break in the words than "cuppa joe" or the British "cuppa".
*My experience and my wife was also a barista for a few years after high school, and also her experience. Granted that latter was 20 years ago.

IMHO, one thing I see little of, on Ars, or Coffee nerdry is the impact of WATER on the final brew.
Which I find odd, because there is SO much focus on water on the final brew with BEER. But on coffee, I basically never hear about it. Coffee shops seem to do one of three things. Nothing about their water. Basic filtering. Reverse osmosis.
I don't see then ever adultering their water.
IMHO, my experience is that the starting water has a strong impact on the final brew. With harder water providing a much softer tasting coffee with reduced bitterness, most noticeable with very dark roasts. The extra minerals seem to buffer the flavor profile more. Same with the starting acidity of the water. More acidic water leads to a sharper and harsher tasting final brew (but also a weaker one). A fairly neutral (but not alkaline) water with medium hardness produces the best dark coffees, with a hint of sodium in the water (a HINT).
Just my opinion. I will walk away now before I get too nerdy and hurt myself.

You should watch that James Hoffman video that was linked above, it will make you feel better with the level of nerding out over water in it.

I accept your offer. Next Monday good for you?
Regarding the Americanism "cup o' joe", being 'Murican I'm familiar with that of course, I've just never seen an American use the word "cuppa" in isolation. I do not mean to bash on J.O.; it's a very minor nit, carry on then.
