some pictures with very few words have been making the rounds on Instagram in the last few days.
Anyone care to share some insights?
PS: found answer. Google.

John Ermacoff is developing some amazing things in coffee (again). I was talking to him Monday. He's built contraptions using ultrasonic generators that create viscous coffee drinks. If you haven't already, I suggest tuning in to his Instagram feed, @jepycoffee.

I had a quick look on Google and I still have no idea what emulsified cold brew is or what Instagram photos you're talking about. Could you give some links?

Couldn't you emulsify using a blender instead of ultrasound?
Kind regards,

Come on, really? :roll:

I did exactly the same search, and it's not clear whether the "imulsified" cold brew method in the Instagram link (which does not come up in the results) is the same as the Coffee Brewing Methods process. The author is very cryptic about "machinery and its filter method". Has anyone else posted anything similar on Instagram or is that the only photo that was making the rounds?

I'm also thinking that if someone's selling this, you may have to read between the lines to get the gist of the method.

Marshall's posted a few pics (still cryptic though): https://instagram.com/mtnairroasting/

Stream of photos incoming...

I'm pretty confident this is just ground coffee and cold water run in a high power blender. The trick is figuring out how to filter it properly because it's so gunky it won't even run through a gold filter or press pot screen. I discovered the sediment settles to the bottom and the suspended liquid looks pretty much the same as the Instagram photos.

Note: If you do this with a Vitamix, you need replace part of the water with ice. I ran both batches on high for two minutes and the first one was steaming hot and absolutely vile at the end.
