Stairway To Coffee Excellency: How To Strain Cold Brew Coffee

Cold coffee is an established brew style among coffee lovers, so, gone days when it was only fashionable for making a cold brew because of the summer heat outside. Cold-brew is an all-seasonal drink now and it can be the same for you too at home if you know how to brew and strain cold brew coffee with proper knowledge.

This smooth, tad bit sweet, and super refreshing brew is actually easy-to-make and will save you a heck of money. Once you make one you can preserve it for a week too! Also, you can heat it up and drink it as a regular black coffee if you’re not in the mood. If you’re a late-morning person, cold brew coffee will totally change your coffee game.


Standard Cold Brew Coffee Ratio

  • First off, this ratio is absolutely flexible. But the given ratio can be a good starting point for you. Later you can change it to fit your tastebud. We advise you to use a kitchen scale but it’s not a must.
  • For each cup of water, you’ll require 1 ounce of coarsely ground coffee. About 1/4 of a cup of whole coffee beans will give you roughly 1/2 cup of ground coffee. Please do note that, in the metric system, 1 ounce equates to 28 grams.
  • Next, bear in mind, you’ll lose some of the water concentration since some will be absorbed by the grounds. That’s why you’re going to make the blend with an equal coffee to water (1 oz. coffee to 1 cup of water) ratio. It will get you the double final yield.


How To Strain Cold Brew Coffee: 9 Ways To Do It At Home

1- Straining Cold Brew With Paper Towels

  1. Place 3 or 4 leaves of tissue paper or clean paper towels over your cup. Use a rubber band to keep them in place.
  2. You should form a receptacle shape with the towels. It will prevent the coffee from overflowing when you start straining.
  3. Run fresh water through the paper towels. It will rinse out the paper flavor. Now, carefully pour the water from the cup.
  4. Now, pour your cold brew coffee through the filter. Pour a little at a time to stop overflowing.
  5. You don’t want to disturb the sediments. Because dropping the coffee too fast will turn the paper towels wet and subsequently may cause the towels to tear.
  6. Finally, when you have strained enough cold brew, discard the used paper towels.

2- Straining Cold Brew With Muslin/Nut Milk Bag

  6. Dump the spent ground coffee after the straining is over.
  7. Rinse and wash the bag immediately or even keep it soaked for cleaning later.

3- Straining Cold Brew With Cheesecloth(s)

Cheesecloths are an excellent choice and they are also food-grade fabrics for straining cold brew coffee. Like the muslins/nut bags, cheesecloths are also reusable. So once you have performed the cold brew straining, wash that bag or cloth to use it later for the same or to prepare other drinks and food items.

  1. Depending on the grade (depends on the weave quality) of cheesecloth, you should use a double layer for a cleaner straining of the coffee.
  2. Rinse the cheesecloth(s) in freshwater. It removes the fabric odors and cleans any foreign material clinging to the fabric.
  3. Fit the cheesecloth(s) over your carafe or bowl. Use some 2-4 clothespins to hold the cloth tightly in place.
  4. Now, start pouring the cold brew coffee over the cheesecloth(s).
  5. Remove the cheesecloth(s) once done straining. Discard the spent grinds.
  6. Soak the cheesecloth in water before cleaning it.

4- Straining Cold Brew With French Press

  5. Once, straining is done to your satisfaction, pour all the brew into a separate cup/bowl.
  6. Discard the grounds and clean the French press.

5- Straining Cold Brew With Paper Filter

Paper filters have 2 shapes – flat-bottomed and cone-shaped. Usually, the paper filters come in as pre-folded. But you are also likely to find some that are not.

  1. A paper filter may be a cumbersome process for you. Only when you do not have a funnel, rigid cone, or a pour-over maker to hold it in place properly.
  2. You may have to use clothespins to stick the edges of the filter to prevent it from collapsing inside the cup during pouring.

How To Make Cold Brew Coffee At Home

All these straining methods are fine and dandy but we can’t let you hang around without speaking about how to actually make the cold brew first itself. Take a quick look below.

Ingredients

We’ve already mentioned cold brew follows a 1:1 water to coffee ratio.

  • So, for a single person serving, you need 3 ounces (85 grams) of coarsely-ground coffee. About ¼ cup of whole beans will give about ½ cup of coarse ground.
  • 3 cups of water.

Steps

  1. In a wide-mouth mason jar, mix the coffee and water. Stir to mix well.
  2. Rest the mixture for 5 minutes and stir it again. This way the grounds will get more exposure to water.
  3. Put on the lid of the jar. Refrigerate for 12 to 24 hours.
  4. Strain your cold brew after the given brewing time.
  5. Let it rest for a few minutes after straining.
  6. Fill a glass with ice. Then fill up half of the glass with water.
  7. Then fill the rest with cold brew and stir. You can even add cold milk to it too.
  8. Cold brew remains well in a refrigerator for up to 2 weeks.


Cold Brew Fun Facts

  • You can use any coffee type to make your cold brew.
  • You can heat up your cold brew to have it as a hot coffee.
  • Only coarse ground is the best ground option for cold brewing.
  • The cold extraction (12-24 hours) brings out fewer of coffee’s bitter substances. So, the end result consists of sweeter notes and a smoother texture.
  • Cold brew is less acidic so it will not upset your stomach. Also, the cold brewing method naturally gives more control to you, so you can fix and change to suit your taste.
  • Cold-brew is naturally a highly caffeinated beverage. So, don’t drink the cold brew straight. Add an equal amount of cold water and ice with the brew to have the best outcome.


Cold Brew VS Iced Coffee

Surprisingly, there are a lot of folks who don’t really know that these 2 are different drinks. We want to make sure that these two delicacies have their proper recognition. Hence, we’re giving you the distinctions between them below.

Iced Coffee

  • The iced coffee is exactly what it says – regularly brewed coffee which is served over ice.
  • This brewing method is quick and requires normal brewing (needs just minutes).
  • After brewing the coffee gets to cool down. Then ice cubes are poured over it.
  • Since, this addition of ice cubes dilutes the coffee, the iced needs extra coffee doses (sometimes doubling the amount of ground for the same amount of water).
  • Some baristas double up on the flavor by making the coffee ice cubes out of these. They simply pour the room temp coffee into an ice cube tray and put it inside of a refrigerator.
  • But it tastes best if sipped immediately after preparing.
  • The extra coffee addition makes it more bitter and acidic tasting.
  • It’s a cheaper but popular commercial drink option.
  • You can add various delicious toppings to it, especially Cold Foam.

Cold Brew

  • Making cold brew requires more care and time. It isn’t as straightforward as an iced coffee.
  • It needs coarse-ground coffee. The coffee has to be steeped in cold water for 12 – 24 hours.
  • After this long steeping, the coffee grounds are filtered out. Leaving you with a strong coffee that can be blended with milk or water.
  • The longer the coffee sits, the stronger and mature the flavor will be. This makes the coffee strong (high caffeine), low in acid, and smooth tasting.
  • Since, it requires skill, time, and more care; the cold brew is an expensive drink of choice.
