The choice between traditional cold brew and the hot bloom method depends on what you like in your coffee. The cold brew method makes a gentle, low-acid coffee. On the other hand, the hot bloom technique brings out more flavor and aroma from the coffee.

With the hot bloom, you first pour hot water over the coffee. Then, you let it sit for about 30 seconds before adding cold water. This way makes the coffee taste more bold, like iced coffee. It has a bit more acid and caffeine than normal cold brew.

Still, not everyone will like this stronger taste. Some people prefer the classic smooth and low-acid cold brew. The way to choose is to think about what flavor you enjoy most in your coffee. Choose the method that matches your personal taste the best.
