Review on Hario V60 Glass Coffee Dripper Size 02 Black - Enhance Your Brewing Experience! by Steve Willis

I've had a size 3 Hario for three years and it holds size 4 filters well. This is the best glass coffee filter I have ever used. However, the outlet at the bottom of the glass dropper is a 3/4 inch diameter hole, so the coffee comes out quickly. To make the best cup of joe with Hario you have to follow a few important steps and you will have the best cup of coffee you've ever had. I use the time-tested method of Nick Cho, the "Coffee Scientist". First, you MUST use a finer grind, e.g. B. Sugar, and then you have to "wet" the coffee. You see, when you put coffee grounds in hot water, the CO2 trapped in the ground bean needs to be able to escape and bubble. The problem is that when the carbon dioxide comes out, the water can't get in. Therefore, you need to "dawn" coffee. When you start pouring water over the ground grains, you must add enough scalding water to wet the entire bottom and then stop watering. Let the coffee soak up this water. Stop and release the gas for about 15-30 seconds. You'll see the base layer swell and expand, resulting in what coffee experts call "bloom". Then you can seriously serve hot water with ground coffee. The "diffusion" cell wall structures of our coffee grounds are semi-permeable membranes, allowing osmotic pressure to push the beverage out of the coffee grounds' highly concentrated chambers into a more aqueous environment. Enjoy your Hario - the king of coffee filters.
