Summer is definitely here! And, while we still think the aroma of a freshly brewed cup of coffee is the best smell in the world to wake up to... we must admit a cup of Cold Brew on the rocks is our favorite way to cool off! So, we wanted to share with you some of our 'secret' knowledge acquired through lots of research & experimentation (a.k.a. "plant watering batches")... and hopefully give you all the tips & insights you need to make the absolute best Cold Brew at home!
First things first... what exactly is Cold Brew? The name (kind of) gives it away... it's coffee brewed with cold water, over extended periods of time. Please note, this is very different from hot-brewed coffee served over ice (that's Iced Coffee!). What makes Cold Brew so different is that cold brewing over (relatively) long periods of time favors the extraction of specific components, while hot brewing methods tend to extract all soluble components. Why? Because the solubility of different components is largely determined by temperature. Caffeine, for example, is only slightly soluble (~1-2 g/100 mL) in cold water, yet fairly soluble in hot water (~65 g/100 mL). Naturally occurring phenolic acids are also significantly more soluble in hot water (which means very little acidity on cold brews!)... yet sugars and larger components (responsible for sweetness & body) are still soluble provided enough time (but be careful... too much time and you'll begin extracting bitter components)!
Now that you understand the chemistry... it's time to have some fun making it! (we promise is a lot easier than understanding all that chemistry!). Here's our step-by-step Cold Brew recipe:
1. Mix 40 oz spring water (~5 cups) for every 8 oz of coarsely ground coffee
2. Steep for 14-18 hours under refrigeration (we commonly do 16 hours, but you can do up to 20 hours if you like a stronger brew)
3. Dilute up to 1:1 with ice/milk/water & enjoy (you'll have enough for 12 large cups)
4. Keep refrigerated and consume within a week (8-oz batch is perfect for 1-2 people drinking 1-2 cups a day!)
Some of our favorite origins to Cold Brew are Central and South Americans... our Florida Cold Brew Blend is actually a mix of two Guatemalan beans at a medium-dark roast level, and was the 'winning' combination in our taste tests (and our best-selling Cold Brew at the farmer's market!).
Happy Cold Brewing!

PS. The new R15 roaster is finally up and running... and we couldn't be happier, or more eager to share it with all of you... watch out for pics/videos in our Instagram and Facebook over the next few weeks... and monthly tours/tastings starting in Sept! (sign-ups available online Sept 1st!). We're also working on some AMAZING new additions (including our first-ever Holiday blend!)
