Cold brew or cold press coffee refers to the process of steeping coffee grounds in room temperature or cold water for an extended period of time resulting in a coffee concentrate that must be diluted with water. It is also sometimes referred to as "Toddy” coffee which is a trademarked cold brewing system.

The cold press process requires grinding coffee beans at a relatively coarse setting (typically only as fine as necessary to allow filtering) and soaking those grounds for 24 hours.  The water is normally kept at room temperature, but chilled water can also be used. The grounds must be filtered out of the water after they have been steeped using a paper coffee filter. The result is a coffee concentrate that is diluted with water and served over ice.

Because the coffee in cold press does not come into contact with heated water, the process of leaching flavor from the beans produces a different chemical profile than conventional brewing methods, providing a smoother and less acidic cup.

Groundwork’s Certified Organic Cold Brew Coffee is sold in 2 formats: bottled, or poured by a barista in-store. Our bottled, ready-to-drink Cold Brew is sold in each Groundwork shop, as well as online at our website and by our retail partners. Groundwork Cold Brew concentrate is regularly delivered to our shops, fresh from the Roastery and ready to be prepared by a barista.  

Below is the recipe for making a cold brew concentrate, as well as the three simple steps required to make cold brew coffee. Note that, when making the concentrate, the ratio of coffee to water is 1:8. Once the cold brew concentrate is made, however, it will be mixed with water at 1:1 concentrate to water ratio.
