What is Cold Brew Coffee?
Cold brew coffee is coffee that is brewed by steeping coarse coffee grounds in room temperature or cold water for an extended period of time, usually 12-24 hours. This extraction method results in a coffee concentrate that is smooth, low-acid, and highly caffeinated.
The main difference between cold brew and iced coffee is the brewing process. Iced coffee is regular drip coffee that has been chilled, while cold brew is slowly steeped without heat. This results in some key differences:
- Flavor - Cold brew is smoother and less acidic compared to iced coffee.
- Caffeine - Cold brew tends to be more caffeinated because the long steeping time extracts more caffeine from the beans.
- Shelf life - Cold brew concentrate can last up to 2 weeks refrigerated, while iced coffee has a shorter shelf life.
Why Make Cold Brew at Home?
Making your own cold brew coffee at home has several advantages over buying it ready-made. Homemade cold brew is known for its incredibly smooth, low-acid taste that many coffee aficionados love. The cold extraction process brings out sweeter, more flavorsome notes from the beans. You can also customize the coffee's strength and flavor profile to suit your personal tastes - go bold or go mild.
On top of that, cold brewing your own coffee can save you money compared to buying it from a coffee shop. Just invest in some basic equipment like a mason jar or cold brew maker, and some high-quality coffee beans, and you'll have liter after liter of delicious cold brew for pennies per glass.
Finally, cold brew coffee makes for a fun and rewarding DIY project. There's something very satisfying about steeping and straining your own batch of cold brew. You can get creative with different beans, brew times, flavors, and serving methods. It's an enjoyable process from start to sip.
Selecting Coffee Beans
When it comes to cold brew, you'll want to use a coarse coffee grind. A coarse grind allows for increased surface area of the grinds, while minimizing over-extraction that can lead to bitter flavors. Browse the Paradise Roasters shop to discover a wide selection of whole bean coffees that are perfect for cold brew. Our single origin coffees provide delicious fruit-forward flavor profiles that shine through the cold extraction process.
For cold brew, steer clear of pre-ground coffee which will lead to a muddy tasting brew. Grind Paradise's whole beans on the coarsest setting right before steeping to maximize freshness and flavor.
Coffee to Water Ratio
The coffee to water ratio is extremely important for cold brew because it determines the flavor and strength of the final product. Unlike drip coffee methods, cold brewing requires a higher coffee to water ratio since no heat is used to extract flavors. The standard recommendation for cold brew is a 1:4 or 1:5 coffee to water ratio. This produces a concentrate that can be diluted with water or milk.
Paradise Roasters specially crafts Island Style Cold Brew using 12 oz of finely ground coffee for every 4 litres of water. This ratio yields a smooth, rich, and flavorful cold brew concentrate. Diluting the concentrate 1:1 with water or milk creates a perfect ready-to-drink beverage. When making cold brew at home, aim for a similar ratio for best results. The concentrate can be adjusted to taste preferences.
Steeping Time
To achieve optimal extraction and flavor, cold brew coffee should steep for 12-24 hours. The long steeping time allows the cold water to slowly draw out the oils and flavors from the coffee grounds, resulting in a smooth concentrated brew. Steeping for the full 24 hours is ideal but 12 hours will also produce delicious cold brew.
Avoid steeping for less than 12 hours, as the brew will taste weak and under-extracted. The slow cold extraction is what gives cold brew its signature smooth, mellow flavor.
The optimal 12-24 hour steeping time produces a well-balanced, flavorful cold brew perfect for homemade batches.
Brewing Vessels for Cold Brew Coffee
When making cold brew coffee at home, you have a few options for brewing vessels that will get the job done right.
Mason Jars
Mason jars are a popular choice for cold brewing. Their glass construction won't impart any flavors to the brew. Look for wide-mouth jars to make it easier to add coffee grounds and filter the finished brew. Quart or half-gallon mason jars work well for most batch sizes.
Cold Brew Makers
Purpose-built cold brew makers are designed for convenience and can make the process practically foolproof. Most cold brew makers use a filter basket or bag to hold the grounds suspended in water. The brew flows into a pitcher or carafe for easy pouring. This all-in-one setup makes it easy to brew and serve perfect cold brew.
Other Vessels
Any non-reactive, heatproof vessel can work for cold brewing. Pitchers, large french presses, and even clean buckets can get the job done in a pinch. You'll need a way to filter the brew after steeping, so make sure you have cheesecloth or filters on hand if improvising your own cold brew setup. The key is finding a container large enough to hold the finished concentrated brew.
Straining the Brew
After your cold brew coffee has finished steeping, the next step is to strain out the coffee grounds. Straining helps produce a smooth, sediment-free cold brew concentrate. There are several filtration methods you can use:
- Cheesecloth - Fold a cheesecloth into a few layers and use it to line your strainer. The cheesecloth will help filter out fine coffee particles.
- Coffee filters - Use a standard paper coffee filter or a reusable metal filter to strain the cold brew. The filters will catch all of the grounds.
- Cold brew filters - You can buy reusable cold brew filters or disposable filter bags specifically designed for cold brew. These have very fine mesh that yields crystal clear cold brew.
No matter which filtration method you choose, be sure to strain the cold brew slowly and in batches. Trying to rush the process can lead to a cloudy final product. Let the cold brew drizzle through the filter at its own pace for maximum clarity and flavor.
Enjoying the Cold Brew
Cold brew coffee is incredibly versatile and can be enjoyed in many delicious ways. Here are some of our favorite methods:
- With milk - Cold brew is great with any type of milk - dairy, nut milks, or coconut milk. The smooth, velvety cold brew combines perfectly with the creaminess of milk. For a special treat, use flavored milk like chocolate or vanilla.
- With syrups/flavors - Mix in your choice of flavored syrups like vanilla, caramel, or hazelnut to create a sweetened iced coffee drink. Flavored cold brew is also wonderful with a scoop of ice cream for an iced coffee float. You can even blend cold brew with frozen fruit for a refreshing coffee smoothie.
- Alcoholic versions - Cold brew shines as the base for coffee cocktails. Combine it with rum, whiskey, amaretto, or your favorite liquors. Irish coffee with cold brew, whiskey, and cream is sublime. For lighter drinks, mix cold brew with citrus vodka, triple sec, and lemonade or ginger beer for a Moscow Mule spin.
Cold Brew Storage
Cold brew can last up to 2 weeks when properly stored in the refrigerator. The key is keeping it chilled below 41°F. Store the brew in an airtight container in the fridge after brewing.
You can also freeze concentrated cold brew in ice cube trays for longer term storage. The frozen cubes can be popped out and diluted with water or milk when ready to drink. This allows you to make large batches of concentrated brew and enjoy it for months. Freezing is a great way to preserve your cold brew and avoid waste.
