Hello sous vide fam, and acquire to a quite caffeinated installment of Will It Sous Vide?, a weekly mainstay where we make whatever we wish me to with my soak circulator.
We were indeed ostensible to tackle this subject final week, yet Portland can’t understanding with sleet and—not usually could we not make it to a store to buy coffee—my coffee consultant couldn’t make it to my kitchen to assistance me out. It wasn’t a finish of a universe however, as I took that event to purify out my freezer, sous-vide style.

But now a object is out, a sleet has mostly melted, and my coffee consultant was means to make it by for a consult. Given a fact that my coffee ambience is, in a word, “basic,” this deliberate was many needed. Though we like to give him grief for regulating terms like “third call coffee” and attending latte art chuck downs, there is no denying that a male (aka Chris of Seven Virtues) knows his beans.
Not usually was Chris kind adequate to move me some unequivocally good coffee (an Ethiopian bean with good “peach, churned berry, and juniper” notes), he even belligerent it regulating a imagination burr grinder. (For we nerds out there: He used a Mahlkonig Kenia.) He belligerent a beans regulating dual opposite settings: that used for auto-drip (which is environment #10 on a Kenia) and that used for French press (#18).
Since a ideal heat operation for coffee descent is 195℉-205℉, we motionless to decoction 4 opposite samples:
Sponsored
- 18.5 grams of coffee belligerent for auto-drip, extracted during 205℉ in 10 ounces of H2O for 4 minutes.
- 18.5 grams of coffee belligerent for auto-drip, extracted during 195℉ in 10 ounces of H2O for 4 minutes.
- 18.5 grams of coffee belligerent for French press, extracted during 205℉ in 10 ounces of H2O for 4 minutes.
- 18.5 grams of coffee belligerent for French press, extracted during 195℉ in 10 ounces of H2O for 4 minutes.
However, before a drift could be combined to a water, we had to get it adult to temperature. The easiest approach to do this is to magnitude out your H2O into freezer bags and set them in a bath when we initial spin on your circulator, that approach your brewing H2O will arrive during your aim heat during a same time as your H2O bath.
It is really critical that we use actual freezer bags, not a sandwich bag like a one we see in a above photo. (I wasn’t meditative and grabbed a wrong bag during initial and that thing sprung a trickle and done me sad.) Once your H2O is ready, supplement in a grounds, put a bag behind in a bath, and set a timer for 4 minutes. Why 4 minutes? Four mins is a brewing time endorsed when creation French press coffee and, given that process is sincerely identical to sous vide, we went with that.
Then it was tasting time. We cut a small hole in a dilemma of a bags and—using oven mitts, since that ish was hot—poured a coffee by a excellent filigree sieve into cups.
I might of might not have done a disaster with one of a samples.
We both tasted a coffees, with Chris regulating a ladle and me holding sips like a normal human.
These were a thoughts (you will notice that one set of thoughts are somewhat some-more useful than a other):
Auto-drip grind, extracted during 205℉ for 4 minutes:
Claire: “I don’t like that. It tastes like coffee that comes out of a pot that has been sitting on a warmer for too long.”

Chris: “This tastes over-extracted. It’s bitter, and we don’t get those good berry records like we should.”
French press grind, extracted during 205℉ for 4 minutes:
Claire: “I like this!”
Chris: “This one is many some-more balanced, and we get some-more clarity with a flavors. You can indeed ambience a fruit notes. This surpasses what we would design from a French press. we would splash this.” [Claire’s note: “I would splash this” is many aloft regard than one would think. There are a lot of things Chris won’t splash that we would.]
French press grind, extracted during 195℉ for 4 minutes:
Claire: “I like this too!”

Chris: “This one is okay, yet somewhat blander than a 205-degree sample. It lacks some of those berry records and some of a sweetness.”
Auto-drip grind, extracted during 195℉ for 4 minutes:
Claire: “Still gross.”

Chris: “Yeah, this is a same [as a 205-sample], yet cooler.”
And now it’s time to ask a favorite question: Will Coffee Sous Vide?

The answer: Yes, and it creates for a flattering good cuppa. More interestingly yet (to me, during least) was how a examination demonstrated a significance of grind-size, something we had deliberate to be a small too changed before. A four-minute descent of a French press-ground representation during 205℉ yielded a beautiful, complex-tasting crater of coffee with all of those betrothed flavors present. The auto-drip representation however was so bad, that even we deserted it as “just bad coffee.”
That being said, it’s positively not a many unsentimental approach to decoction coffee; it’s a bit awkward and it requires about half an hour of wait time while a bath and brewing H2O come adult to temperature. However—unlike a certain coffee brewing complement that rhymes with “pharaoh chess”—it would be flattering easy to scale up. You could decoction a large bag of ideally temperature-controlled coffee, aria that whole thing in a large pitcher, and serve. Though Chris won’t be replacing his flow overs with sous vide coffee, he couldn’t repudiate that it done a good crater (better than a French press in his not-so-humble opinion). Given his high standards, we cruise this a sous vide victory.
