The Deep27 fits really nicely on a Glencairn glass!
Inspired by this post, I've been experimenting with drinking my coffee out of my Glencairn whisky glasses. I've poured two at once from a carafe, but for a single serving I did not want to lose too much temperature. Found that the Deep27 fits _perfectly_ on top of a Glencairn glass. It'll brew roughly 150ml before the paper starts hitting the brewed coffee. A quick stir and the thing's ready, I'm not sure what to think of the experience yet but I'm starting to see it.
