Inspired by conversations on the Food52 Hotline, we're sharing tips and tricks that make navigating of our kitchens easier and more fun.

Today: What's the big fuss about cold brew? Let us explain.

Cold Brew Coffee

Iced coffee in the summer -- it's a given. It's cold, it's refreshing, and for many of us, it is a necessity. But what's the big fuss over cold-brewed coffee? 

There are a few things about a cold-brew that have made it into the summer beverage du jour. The first thing most people note about cold-brewed coffee is the lower acidity level. Since the grounds never come into contact with the intense heat of boiling water, the flavor profile of the final brew is different than with drip coffee. Similarly, when hot coffee is rapidly cooled, it creates a slightly bitter taste. One of the major draws of a cold-brewed cup of iced coffee is that it will have a smoother, slightly sweeter flavor.

Cold Brew Coffee 

Finally, a cold brew is pretty much ideal for iced coffee because it is more concentrated than a traditional, hot-brewed cup o' joe; the addition of ice and cold milk or cream will dilute it just enough without watering it down.

Iced coffee is more expensive than hot coffee, and cold brew is even pricier. Yet many people are willing to pay extra because they are intimidated by making it at home.

You're in luck; with only three steps, cold-brewing might be the easiest coffee method out there.

Cold Brew Coffee

Grind, Soak, Wait

The ratio of coffee grounds to water is pretty debatable; personal tastes will dictate your own. A good place to start is 1/3 cup of ground coffee to 1 1/2 cups of water. After you find the ratio that you like best, you can adjust the size to fit as large a brewing vessel as you want. The type of grind, however, has been universally decided upon: it must be coarsely ground. A smaller grind will result in a cloudier liquid.

Put the coffee in your brewing container and add the water.

Cold Brew Coffee

Stir to make sure all the grounds have been moistened, then cover and place on the counter or in the fridge over night, for at least 12 hours.

Cold Brew Coffee

In the morning, strain twice through cheesecloth or a fine-mesh sieve.

Cold Brew Coffee

Add ice, milk, or your other favorite coffee companions and enjoy.

Note: To make a simple process even simpler, this can all be done right in a French press: Add the coffee and water and put the lid on but do not plunge. In the morning, press, pour, and drink -- easy enough to do without caffeine.

Very nice article (especially I like the Pictures with cream) on how a Cold Brew Coffee can be easily done with a traditional steeping method.
You also mentioned the way using a French Press and there are a bunch of other methods avialable. We from ColdBrewTest.com compared them (e.g. French Press, Toddy, Cold Drip...) and gave some comments on each methods advantages. Feel free to have look.

I use a nut milk bag and a 2 quart pitcher. Easy filtering. When I'm ready, I wring out the nut milk bag. Very few containers, and the only waiting time is the brewing.

I've tried the nut milk bag route, but the mesh wasn't quite fine enough for the cheapie store brand ground coffee I use most of the time...lots of gritty sediment. I plan to try again with some coarse ground coffee, though!
I'm still loving my muslin bags -- a 6x8" one holds a good 1.5 cups of grounds with room for them to swirl around a bit for maximum grounds to water contact in my 2 quart pitcher!

I'm employing a somewhat more haphazard/renegade cold brewing system right now...

Empty fresh juice bottle from a uk supermarket full of ground coffee and water. Refrigerate 12-18 hours.
Filter through aeropress into mug, then pour into jug (yup- super time consuming).
Wash bottle. Pour filtered cold brew back into juice bottle and return to fridge.

It worked pretty well when I tried it a few days ago, though It didn't come out quite as concentrated as I was hoping. I've now changed quantities a bit- I'm actually taking a punt at the ratio I go for when brewing a cup of aeropress (1 level scoop, inverted method plunger at about number four, water up to just below the end of the device- theres about 4.5 times that mix in the juice bottle) hoping that will produce a meatier concentrate that will last longer and will stand up to milk a bit better (last brew was a bit weak for the milk, though was fantastic with a dash of extra cold water and some ice)

you are all working way too hard for that well deserved gourmet iced coffee or latte
no tools no vessels no silt no filters no magic just a sachet of gourmet black coffee pour contents in a cup add boiling water stir lightly add ice and enjoy EVERY TIME contact [email protected] for all the info etc check it out

I've tried the "loose in a bucket" method described above, but got tired of waiting for FOREVER for it to strain through, plus too many vessels and tools. I then bought a 1.25 quart french press, but it doesn't make enough at once - having to wash it out every day sucked. I still had to filter out some grounds, too (cheapie press, filter has tiny gaps at the edges).
I then thought of big muslin bags! Ordered sme 5x7 cotton bags from amazon, park 1.5 cups grounds in one, use a rubber band to clse and plunk it into my 2.5 quart pitcher in the fridge. I just leave the bag in until I've finished the pitcher and let the brew get stronger each day...even sometimes adding a bit more water if I see there's not going to be quite enough for the next morning. When I'm done, I squeeze the loosely packed bag of the last drops I can get, then 'flatten' it out on a small wire rack over a plate to dry for a day or so, then dump it out in the garden or sprinkle it over the lawn.
The bags are totally washable, reusable and I never have to mess with a strainer or filter. I never worry if my grind is too fine because the bags hold all but the very finest silt (less than a tsp per pitcher) inside.

Are you making this regular strength? Because I'm one of the French press users, and I make mine very, very strong -- coffee concentrate in fact. If you make it that strength, no matter what your method, you'll have plenty to last more than one day. Just be sure to keep the concentrate refrigerated, then just dilute to the strength you desire. You can even make a hot coffee with the concentrate.

Hi, beejay45 -- The main reason my press didn't work out for me is because my son and I both consume cold coffee drinks at a phenomenal rate! Even with the 3 cup yield of concentrate (1 part coffee 3 parts water) from my press, we still would have to set it up every night and wash it out every day. More grounds added, the less actual liquid yield...and since I also strongly believe that there's a certain saturation point where the water just isn't extracting any more goodness, adding much more coffee would be a pointless waste of money.
I've experimented with ratios and found that the 1.5 dry cups (probably a bit more as I use a heaping 1/4 c. scoop times 6) of grounds in 2 quarts (8 cups) of water (so that's...um...about 1:5? I think that's the ratio most recipes I've seen recommend) gives the results that suit us. We use it with flavored simple syrup and half n half either over coffee ice cubes or blended into a frappe. I will fill a 1 liter bottle halfway with the coffee/syrup/half n half, freeze it overnight then fill up with more in the morning before work to have cold coffee all day (I use a nifty crocheted 'bottle cozy' to carry and prevent condensation drips). My son jokes that he'd do a coffee IV, but then he wouldn't be able to taste the flavors he's come to love from "Mom's Brew". His friends envy his great tasting drinks and I can't keep the pitcher full when one of them visits our house.

I'm very glad that your press works so well for you, though!!

Hi, cattyb! Wasn't touting the press, just the concentrate. ;) Are you familiar with kakegori (if I'm spelling that right), the Japanese shaved ice thing? I use my coffee ice cubes in that for hot weather, top with sweetened condensed milk, or your choice of creamer and/or syrup or liqueur. Whatever you like, it's great and really hits the spot when you're sweltering.
I'm not supposed to drink coffee at all, but the cold brew doesn't release all the oils that cause me problems, so I can have the occasional indulgence. Have to choose my moments, though. ;)

Oh my stars and garters, that sounds heavenly! It was 98 degrees here yesterday and I could have used two or three coffee 'snow cones' throughout the afternoon.

About the press/concentrate thing... I didn't mean to de-mean, if you know what I mean. :-} I really AM glad it suits your needs so closely! I just tend to get all wordy and go off on tangents when I get excited about something.

We'll occasionally use our "dregs", which are pretty concentrated, to make coffee ice cubes that strengthen rather than dilute... or for baked goods...or just as an excuse to add even more sweet creamy goodness to the last cup. >^..^<

Hmmm so if you only have to let it sit over night, why not just use coffee pads that you can take out and discard after?

Is the water supposed to be hot (boiling?) or cold when added to the ground coffee?

I make cold brew as per instructions above and strain thru a few un bleached coffee filters (I need to use them as my brewed coffee is made with keurig style refillable pods or an old school italian Moka pot). It works pretty well and I'm rewarded with wonderful coffee! May try my tea infuser "kettle" , but this works. Tomorrow I'm definitely tryng the martini shaker idea with almond milk, sans agave!

I make cold brew all the time. After many times of straining the grounds out of the coffee I found a better way, for me anyway. I use NEW knee highs/panty hose. I wash them and put my grounds in and tie them up. You can get several out of one knee high. It's the same as nylon bag/filter. When coffee is done just remove bag and use it on plants discard. Nothing fancy at all but it works good.

When my favorite coffee pot finally expired yesterday, I looked for a 'back up pot' which I think I sold in my last move. (I knew better) But I remembered my old cold brew system which honestly always made the best coffee but I quit using it because it is so good I drink way to much and coffee prices are so high. Anyway I'm trying to remember the water to coffee ratios and the time to 'brew'. I'm starting with 1 1/4 cup ground to 2 cups water. But it seems like I remember a pound of ground coffee to make the entire carafe. Of course the best feature is the concentrate can be diluted as much as you like. Herein lies my issue as an old New Orleans girl I like it strong! I would like to get the most concentrate from the amount of grounds used. Any suggestions appreciated. To the design system and the cook, the Toddy System (which is what I think mine is a great way to handle the messiness and easy to clean rinsing and then into the dishwashet. I've never tried the French Press which is in the cabinet for that reason plus the cold brew keeps in frig so well. You only have to wait for the microwave

I first tasted delicious cold brew coffee at my New Orleans friends and noticed that they used a vintage Toddy maker. I bought one of my own on Amazon...the design has never changed and it makes perfect cold brew coffee which I have every morning.

I am an industrial design student doing research for a client that intends to manufacture a cold brew coffee system, not entirely unlike the Toddy Cold Brew System. I’ve noticed that there is a multitude of articles on how to make cold brew coffee with common household items, but there is not a great number of commercially available cold brew coffee makers.
Is there a sense of pride associated with making your own cold brew coffee with your own assembled equipment? Is this a trait of the cold brew culture? I am trying to identify the motivation for the home made systems and the possible preference over commercially manufactured ones.
If you could design a cold brewer, what features would you most like? Which features (or lack thereof) are frustrating?
Any replies are greatly appreciated. Thank you

For me, a cook who's infusing, then filtering, things all the time for one use or another, I just went to my fallback French press for cold brewing coffee. I am not a fan of single use appliances, but having said that, if your client were to make a cold brew coffee system that would streamline my infusing and filtering of various things, I'd definitely give it a go. My number one requirement is something that will give me a good infusion yet not leave me with a sludgy mess that needs to be filtered and refiltered and re...ad infinitum. The French press does this quite well, even for things like ground coffee. The lack of bitterness in cold brewed coffee is a factor of the low temp, so that wouldn't be an advantage in an "appliance." But something that allowed me to just pour off an almost clear (of particles, not color) liquid would be ideal.

I've never tasted a commercial cold brew that is as strong as what I achieve at home. And I follow the proportion of water to coffee that the manufacturer intended.

More gentle taste. Voila. As much better as sun tea is to tea that was scorched by the boil.

I use my large pour over cone. put grinds and water in a plastic bag in the cone and freeze overnight. Remove from plastic bag in the morning and place back in cone with filter paper. Allow to thaw for several hours or more.

hi, i've just made 500 ml of cold brew yesterday. something that i improvised was using the hario v60 as the filter. Can anyone tell me what they think about my method?

Hi Obi - At Cold Brewed Co., we strongly believe that a little extra filtering goes a long way. As long as you've steeped your cold brew for long enough, putting it through a v60 is a great idea...you'll end up with an extremely smooth brew.

What is the toddy system? I'm loving summer with the french press method. However you make it, I agree with John about the bacteria. Keep it in the fridge whatever the method. I was explaining the cold brew concept to my mom over the phone who thought it sounded great. Since she was at a book store with a coffee bar she dutifully asked if the iced coffee was cold brewed. Uh well, she does live in Floriduh. She got a sweet tea
