If you use it the right way up, add a small amount of water to the grinds and stir to make a paste, then wait a few seconds before adding the rest of the water, it limits the drip through to next to nothing. Also putting the plunger in so it’s just the tip in, (ooh err, missus), stops the coffee running through because of the vacuum effect.
You know when you’ve hit full on pretentiousness, when you take the Aeropress, Triangia kettle and stove, and make good coffee on the beach. 😳
