I Reinvented a 300-Year Old Drink 

Peanut Butter Washed, Curd Incubated Espresso Martini (aka the Best Espresso Martini Ever) PB-washed vodka Smear a generous portion of peanut butter on the bottom of a mug Pour about 300 mL vodka on top (gently, so as not to disturb the peanut butter) Cover and let sit at room temperature for 24 hours Curd-incubated espresso Prepare a 15% citric acid solution (you can buy citric acid powder online; make a 15% solution by adding 15 g of powder to a measuring up and filling it with water to the 100 mL mark) Curdle about 100 mL of milk using the citric acid solution Add citric acid in small batches, 1-5 mL at a time, and stop the moment you see the milk start to break (adding too much acid will make the final drink taste off) Spin the curdled milk in a centrifuge (4000 rpm for 1 minute) or filter through a coffee filter If centrifuging, pour off the whey (save it, you’ll need it later) If filtering, keep the whey (save it, you’ll need it later) Pull two shots of your favorite espresso (ideally low acid coffee) If you centrifuged the milk, pour your espresso in the centrifuge tubes that contain the curds. Cap the tube and shake vigorously, then centrifuge at 4000 rpm for 1 minute If you filtered the milk, pour the espresso on top of the curds in the filter (gently, so as not to disturb the curds) Note that this might be hard to do with such a low volume of coffee - if it doesn’t work well, try it with cold brew At this point you should have curd-incubated coffee Build the drink In a cocktail mixing glass, add: Ice 2 oz peanut-butter washed vodka ½ oz Kahlua 1 oz curd-incubated espresso ½ oz whey ¼ oz simple syrup Rest easy knowing no one will ever outdrink you *Note: instead of effing around with a centrifuge or filter, you could try to adapt this recipe that uses milk powder: punchdrink.com/articles/milk-punch-powder-technique/ If you do, leave a comment and let us know how it went!!!

Drinking before noon. "FOR SCIENCE!"

Lipophilic compounds (such as many bitter tasting agents) will diffuse into the milk proteins and thus get removed from solution when those are denatured and precipitated. Btw. your blood contains Albumine and alpha-Glycoprotein in order to allow for transporting lipophilic compounds in the watery medium that is blood plasma - it's the same principle (with thousands of papers available) minus the precipitation. Greetings from a pharmacologist.

"Chemistry works" (14:40) Darned straight it works. Nice video. Thanks for sharing.

I could totally see a new bar concept called The Centrifuge where they serve milk-washed cocktails.

I love this channel. This channel is criminally underrated!

With this and some brined chicken working your way towards a fantastic Reactions dinner party.

I love this channel, I learn something new every fricking time.

Damn. Now I need a centrifuge for cocktails 😂

In the future, I'm going to cite this video as a source for my scientific paper. 📜

You have to do this a spinoff serie ! Every month a new cocktail ❤️

I could stand to see more cocktail or cooking themed Reactions videos.

14:28 Fluffy Cameo if you're interested. 😂

Just reminded me about Pilk, that is a tasty beverage I haven't had in a long time.

Thank you for this video, now I can show it to the people that show me the video of the milkwashed coke that supposedly proves coke is toxic or something, I hate when people just believe any TikTok they see

I really wanna see you have other people try it. Still a really nice video

RU-vid needs more science content and men who can make long sleeve t-shirts work. This did not disappoint.

I was sceptical at first, but I just tried milkwashed Jack Daniels and it is absolutely delicious. I didn't have any citric acid, so I used a little bit of vinegar.

this was my favorite reactions video to date! awesome work George!

Huh, I hadn't heard of milk washing before but that's pretty interesting technique to separate hydro- and lipophilic compounds out of things. I'm not much of a drinker but ngl I kinda want to try George's spin on the espresso martini now 🤔

This guy does not react the way i do when i taste vodka

For flavour purposes it should be interesting to curd the coffee directly with the milk instead of separately. I'm pretty certain that the extractions aren't the same

When he's basically describing alcoholic cheese-making lmao Just get cheese cloth and collect the curds that way, folks :) Way easier than buying a centrifuge.

I also kind of want to see How To Drink try this over several different drinks. But maybe a guest spot, because as much as watching him get slowly drunker and using a centrifuge would be fun...

Loved that and learned as well.

Wait... is this technique why adding lactose to beers, meads, liqueurs, etc. is supposed to give it "that old-fashioned flavour"?

Great info! Butter also contains milk solids, which you missed mentioning during the section on fat washing.

so, what i heard is: i should buy a truckload of vodka, put peanutbutter into the bottles and resell it for twice the regular price. ;)

Your fame has gained another subscriber. Really enjoyed this video. (Now wondering if I can speed up the infusion using a vacuum chamber. Could this be a new hobby? 🤣)

I love milk washing. Is there any sort of ratio you could point to for how much citric acid or citrus juice we might want to add?

Interesting stuff, I can see some delicious experiments in my near future! Here's to 9am drinking! (it's ok if it's in the name of science!)

Fascinating

Intriguing to say the least, but it was fun to watch and something good to learn as well😊

I used to drink coke and milk bc it tasted so good. Fascinating to learn the science of it

I have some coffee that is so acidic that it curdles the milk unless I put a lot of milk or somehow increase the pH. Maybe I'll try straining it...

Awesome video! Going to try milk washing (and fat washing, been meaning to for ages). I just wish you had also compared the espresso martini with one that was milk washed, and/or your three part process minus the peanut butter. Curious about removing its influence

1:53 Let me just pull up the wiki page for milk washed🤣

I didn't catch the rationale for including the peanut flavor variable. How do the drinks compare without adding peanut to the typical recipe?

Bro LOVES vodka at 9:28 am

Missed pilk opportunity :(

Can you mix coconut oil with coffee or tea and centrifuge it? Some doctors here keep recommending this to lose weight.

So when sat on a tuffet, eating her curds and whey was she just drinking milk?

Kool!

cheers

Mmmm cocktail cheeses.

What if you just don't brew the tea as long?

They really had to twist your arm to do this one, huh?

0:50 I feel the only time this can be a thats what she said is when one of my fellow transfems says it xD Not me personally tho, im intersex XXY and its def far from bein anythin describable as too long xD

Ok. Um thanks. But what if A) you don't own a centrifuge, and/or B) you want to make cocktails for more than one person in less than half an hour.

Video pitch. I make alcohol and drink it for...science...yeah the science.

OO OOH

But tannins are good for you! Don't!!

I almost didn't click on this video because of the channel name, I thought this was one of those "react" channels

Cmon now, do you actually think science can make taking drugs even more enjoyable? Wait...nice

you didn’t remove the citric acid

🥱

Now I want to see what @HowToDrink does with this

now that you have revolutionized the alcohol industry do you think you will be revolutionizing the ketamine cupcake club? or the Amphetamine tea time? are you gonna get into cannabaking as well or is that too intimidating bc they already know what they are doing?

I want my 16:57 minutes back

Milk "washing" obviously adds acid. That was the first thing i thought when he added acid to curdle the milk.

@DANFELLOWScoffeecocktails should definitely try this!
