Yes, you can adjust the strength or flavor of your cold brew coffee by using a cold brew maker. The strength of the cold brew can be adjusted by varying the coffee-to-water ratio or the steeping time. To make a stronger brew, you can increase the amount of coffee grounds relative to water or lengthen the steeping time. Conversely, for a milder brew, you can decrease the coffee grounds or shorten the steeping time.
