Cold(ish) Brew Sous Vide Coffee
Posted by : Alex Mills /
It's summer time.
And cold brew caffeine, er, coffee, is that refreshing, trendy beverage we can't get enough of. Smooth and flavorful, without the bitterness that can come from an over-extracted brew cooked with off-boiling water, cold brew satisfies your taste for a cold beverage, along with your high standard for extra quality coffee.
Plenty of folks have developed their own at-home methods for DIY cold brew. Most of them take a day or so of "steeping" the coffee inside your fridge. If you can wait a whole day for your smooth coffee treat, by all means.
But, the sous vide community found a hack. Marry the best-of-worlds smooth taste of cold brew with the time saver of this low-and-slow cold(ish) brew coffee. Only takes a couple hours and you'll have that delicious cold brew flavor.
Then, store in the fridge for up to a week. That's right, unlike the flavor of hot coffee which degrades as it cools, the flavor of our cold(ish) brew coffee will keep in the fridge for up to a week.
It's like Christmas in June.
*note: we found a little contraption on Amazon that lets you do DIY cold brew in a cute XL mason jar, complete with built in filter and a pour-spout. So we've used that in this recipe. But, it isn't necessary at all... you can even dump the water in a freezer bag, mix in the grounds and seal up the bag. At the end, you'll just need to filter out the grounds. A pour-over filter works great for this.
- 1/2 cup coarsely ground coffee to every 4 cups filtered water (we recommend setting 18 on your coffee grinder if you have one)
- sous vide set up with our Gramercy Kitchen Co sous vide immersion circulator
- DIY cold brew maker or a large freezer bag and pour over filter
- coffee fixins of your choice
Set up your GKC sous vide immersion circulator in its water bath and program the machine for 150F for 2.5 hours.
Ground your coffee - we recommend size 18 on your coffee grinder if you have one. A French press coarse grind works perfectly for this - a more fine grind can produce coffee that is too strong or bitter.
Pour the filtered water you'll use for the coffee into your container. Then, fill the metal filter with your coffee grounds and close the lid. If you are using a freezer bag, just combine the water in with the grounds and use the water-displacement method to seal the bag.
Once your water bath comes to temperature, place the jar in the water bath and let brew for 2-2.5 hours.
Once your cooking cycle has finished, remove the jar. If you used a freezer bag, use a pour over filter. Then, cut a small hole in the corner of the filter and drain your coffee through that hole into the filter and then on into container you'll store it.
From here you can either add a bunch of ice and enjoy immediately or let the drink chill in your fridge for up to a week to enjoy later.
