If you're curious, try a small batch of medium roast cold brew next time you shop. Brew it the same way you usually do, and taste it side by side with your usual dark roast. Pay attention to the finish—does it linger with a pleasant sweetness or leave a bitter aftertaste?

You don't need fancy gear. A simple mason jar and a fine-mesh strainer work. Use a 1:8 ratio of coffee to water, steep 12–18 hours in the fridge, and dilute to taste. That's it.

If you want to make it a daily habit, grind your beans fresh and store them properly. Freshness matters more than roast level, honestly. Check the roast date on the bag—if it's older than a month, you're not getting the full picture.
