SCIENCE: Vac Sealed Whipper Gastro-Micro Cold Brew, The “El Bulli” of Coffee
This article is part of our special Back To School Week series:
Everyone remembers where they were when Billy Wilson introduced “Crema Loves Creme Fraiche” featuring espresso caviar in 2006.
Espresso caviar was everywhere. You couldn’t walk into a “third wave café” without seeing it on the menu. Well… move over 2006, we’ve got this year’s hot ticket offering: pressurized cold brew coffee!
James Hoffmann, Jay Caragay and other Wylie Dufrense Molecular Gastronomites are currently discussing an exciting new trend: infusing aromas with cream whippers. Basil in mozzarella. Cacao nibs in liquor. Ground coffee in water. Bold steps to take a page from restaurants like El Bulli and The Fat Duck.
From JimSeven:
Could pressure add the necessary energy – perhaps even allow rapid cold brewing? I loaded a syphon with 15g of coffee and 250ml of water, pressurised it, shook vigorously and then waited a minute and released the pressure. I strained it through a V60 and tasted it. Disgusting, barely any extraction.
“More time….” I thought – so I set up a longer brew. The results were very tasty. I needed a control sample, so last night I experimented again.
We here at Sprudge.com applaud this new concept! The current state of cold brew is mostly appalling.
Join the discussion at JimSeven. Though we are a little concerned with one commenter’s warning:
Please be carefull, as N2O liquid mixtures may form shock sensitive explosives.











Caragay followed up that pressured brewing with vacuum brewing:
