How to Make Cold Brew Coffee in Under 3 Minutes Using Ultrasonics

They used THE cold brew recipe Since THE New York Times For their experiences, with A water-coffee report of 10:1 For both cold- And hot brew batches. (Hot brew Normally has A water-coffee report of 20:1, but THE team research has control variables as a lot as possible.) They thoroughly control When water was added has THE coffee land, how long has shake (Or stir) THE solution, And how best has press THE cold brew coffee.

THE team find that For THE lighter roasts, caffeine content And antioxidant levels were roughly THE even In both THE hot- And cold brew batches. However, there were significant differences between THE two methods When AVERAGE- And dark roast coffee beans were used. Specifically, THE hot brew method extracts more antioxidants Since THE grind; THE darker THE bean, THE bigger THE difference. Both hot- And cold brew batches become less acid THE darker THE roast.
