Cold brew coffee is just that: coffee brewed when cold. Though it takes longer that its high temperature cousin, steeping coffee grounds in cool water for a longer period of time unlocks rich, full-bodied flavours you won’t find through any other brewing method.
Saturate all the grounds by gently rotating the brewer. Allow to brew for 8-12 hours. Remove the filter, place the top of the bottle back onto the glass base, open the spout, and pour over ice.
P.S You can store it in the refrigerator, & drink within 3 days.
