What’s the difference between Iced Coffee and Cold brew coffee?
Cold brew is ground coffee steeped in cool water …mostly overnight process. Iced Coffee is brewed in hot water, then cooled over ice. Because of the difference in brew methods people claim the cold brew coffee is sweeter, smoother and less bitter than iced coffee.
Although cold brew coffee can take longer to develop than drip coffee, it is completely worth the wait. Cold brew coffee is smooth almost creamy like and a little bit sweeter tasting too. You don’t get those bitter notes like you do with drip brewed coffee.
The cold brew coffee maker I use is from OvalWare, but there are many different types of cold brew coffee makers out there. Some that are automatic too.
But if you don’t want to invest in a cold brew maker, you can always use a mason jar or water pitcher. The result is basically the same. Delicious cold brew coffee.
The recommended brewing time for cold brew coffee is somewhere between 12 to 24 hours. The longer you let the coffee steep, the stronger it will be. I’ve let the coffee brew for a little over 24 hours and it was still fine. But I love a strong cup of coffee.
When you coffee is done steeping, you will need to strain the coffee grounds. If you are using a cold brew coffee maker, you simply remove the filter containing the coffee grounds.
If you are using a jar to steep your coffee, you will need to filter out the coffee ground through a fine-mesh sieve, coffee filter or cheesecloth. To strain the coffee, place the filter into a mesh sieve or drape the cheesecloth over the sieve. Then pour the coffee over the filter to separate the grounds from the coffee.
Using 85 grams of freshly roasted beans made such a rich concentrate and the overnight steeping brought out a smooth low-acid flavor that I loved. I used the mason jar method and strained through a coffee filter which gave me a very clean brew with no grit. It was super convenient to make and kept well in the fridge for the next few days. Perfect for my busy keto mornings.
I love how simple this recipe is and that it requires just two ingredients. Using freshly ground beans really makes the flavor pop. Five stars for making keto mornings so much better!
