How to Make Cold Brew Coffee Shelf Stable
A cold brew coffee shelf is a container for making and storing cold-brewed coffee. There are many recipes out there for how to make iced coffee, but the goal of preparing the cold-brewed coffee shelf is precisely to allow you to make it in advance.
This gives your iced coffee time to age to achieve maximum flavor (this process is called “cold brewing” or “cold steeping”). Cold infused coffee can be prepared within 30 minutes. However, allowing the mixture to steep overnight will result in a significantly more flavorful end product. In this article, I will discuss how to make cold brew coffee shelf stable. So let us get started.
Stepwsie Guide on How to Make Cold Brew Coffee Shelf Stable:
What you’ll need
- 1 L glass jar or non-reactive container with a tight-fitting lid. We use the Anchor Hocking Glass Jar 1L, which can be found on Amazon.com for under $10.00.
- 2 tablespoons of coarse ground coffee to start your cold brew; adjust according to taste after complete brewing.
- 3 cups of room temperature filtered water, and we recommend using filtered water because it produces less sediment when brewed and ensures no impurities in your final product.
- A funnel and fine-mesh sieve or cheesecloth to strain out the coffee grinds.
- A timer of some sort.
Warm the jar by running it under hot tap water for a few minutes, and this will make it easier to pour the cold filtered water into the pot without breaking or cracking it. You can also let your coffee sit out at room temperature for about an hour before brewing if you like;
we do not recommend using hot water to brew with because it extracts very quickly and may produce an overly acidic product. Next, grind your coffee coarsely (big flakes like kosher salt). We use our Porlex Mini grinder, which is small enough to travel with but more than capable of producing a perfect grind for use in cold brew;
however, any similar device should work just fine. Add the ground coffee to your jar and fill with 3 cups of filtered water slowly to allow any air pockets a chance to escape without pouring out too much liquid, then cover with a lid and shake vigorously for about 10 seconds. Allow your cold brew coffee to concentrate on sitting overnight at room temperature (about 8 hours), occasionally stirring if you think of it.
Finally, pour the cold brew through a cheesecloth or fine-mesh sieve lined with a funnel into another container with a tight-fitting lid; using the backside of a spoon is helpful here. You can now enjoy your iced cold brew over ice or refrigerate it for later use!
Once your cold brew has been strained from its liquid state, you can choose to store it in the refrigerator (we recommend no longer than 14 days), or you can make shelf stable cold brew coffee concentrate; the choice is yours.
To make shelf-stable cold brew coffee, allow your concentrate to sit at room temperature for about 3 hours and then place it into a sterilized jar and seal with a lid leaving as much air out as possible;
this will cause the natural oils which have risen to the top of your cold brew during its overnight fermentation process to fall back into solution and create a fresh, flavorful beverage that won’t spoil as quickly as freshly brewed iced coffee would. Be sure to use it within one week of making, though, because those lovely fatty acids begin to degrade after this time, which reduces the shelf life even more!
Precautions While Making Cold Brew Coffee Shelf Stable:
Before we begin, I would like to warn you that the shelf life of this coffee is entirely dependent on how it’s stored. Please be aware that cold brew coffee is best served within seven days of making it. If you’re not going to drink all the coffee within those seven days, please consider freezing or canning some (sous vide) as discussed below.
Cold Brew Coffee Shelf Stability: Cold brew coffee has a different flavor profile than traditionally hot brewed coffee, and what may seem strange at first is part of this difference comes from oxidation which occurs naturally in your cup over time; however, unlike traditional iced (hot brewed) coffee where extra oxygen and sunlight greatly expedite these actions effects, iced cold brew is wholly protected.
Benefits of Having Cold Brew Coffee Shelf Stable:
1) You Save Money: Cold Brew Coffee is cost-effective as it can be made in advance and stored for several days; you only need to add cold water, milk/creamer of choice, and ice if you like iced coffee. So it’s cheaper than the regular hot brewed day-to-day joe and more affordable than high-end cold brews (trust me, we’ve tested both;)).
2) Less Acidic: Coffee tastes better when less acidic, even though some might prefer a slight acidity. Here’s how we make our Cold Brew Coffees at home: We use 2/3rd of a cup of medium grind (powdery fine!) coffee beans;
pour 8 cups of room temperature water on top of the grounds, mix it around a few times, and set aside for 12-24 hours. Then we pour everything through a fine-mesh strainer twice to eliminate any coffee powder at the bottom.
When it comes to hot brewed coffee, if you leave the coffee on the burner too long, some acids will evaporate while some things in your coffee will oxidize, producing more acidic flavors.
3) You Get More: We make sure all our cold brews are 1/3rd stronger than their respective counterparts (i.e., more concentrated). For example, this Almond Cold Brew is made with 2 cups of ground espresso roast beans and 16 cups of room temperature water resulting in double strength cold brew that can be diluted to your liking with water and ice or coffee creamer of choice.
4) More Flavor: Cooking something on low heat for a long time makes it more flavorful because slow cooking helps the ingredients break down and make smaller pieces releasing flavors that would otherwise be locked within them. In some cases, these substances help create new flavor profiles and react to one another.
For example, this is what happens when you cook red meat; if it’s cooked for a long time at a low temperature, then all sorts of spices will be added into the pot, giving it a rich taste.
I hope this article has offered you all the necessary instructions on how to make cold brew coffee shelf stable. Thank you and have a nice day!
