Does Heating Up Cold Brew Coffee Make It Acidic?

Cold-brew coffee’s naturally lower acidity is well-known and appreciated by the general public. However, few people know that this property is attributable to the cold brewing procedure and is distinct from most hot coffees. No. Given its lower acidity due to the way it was made, does heating it undo all that incredible work? No, of course not. A warming cold brew won’t change its acidity, which is a quick answer. A significant factor in why cold brew cannot be made more acidic by simply adding more coffee grounds during the heating process is that the grounds themselves give coffee its acidity, not the process of heating it. The percentage of water added to your batch is more important than the temperature when determining your cold brew’s acidity and caffeine content. Adding more or less water won’t do anything but dilute or amplify the concentrate’s effects, which are already present in the concentrated form. You may feel like you’re cheating by heating your cold brew to drink it warmly, but don’t worry; you’re not doing anything at that moment to alter the strength of your brew in any manner other than by adding water.


Given the widespread use of hot coffee brewing methods, it may seem counterintuitive to heat cold brew, but that’s precisely what it does. If you prefer your hot coffee with the low acidity and creamy, smooth flavor of cold brew, it’s well worth your consideration. For those who have difficulty making hot coffee in the morning, warming either cold brew concentrates or ready-to-drink cold brew is an easy and quick method to get your fix of java. Using a steam wand to heat the cold brew or overheating the cold brew in a microwave can result in an unpleasant taste, as can overheating the cold brew. If you’re willing to put in the time and effort, you’ll soon discover that cold brew coffee isn’t only good for the summertime; it’s also great for the fall and winter months.
