Can I heat the cold brew?Updated 12 days ago

Yes. Of course you can heat it up and it will still be one of the smoothest cups of coffee you have ever had. For a true hot coffee connoisseur, they will note a difference (less acidity, less bitterness) than a hot cup because this is, well, heated cold brew which is chemically different. You can absolutely heat in the microwave as long as you ensure you don't overheat/boil the coffee. Best, but least-used method, is to heat on the stovetop under low heat.
