askaboutI like the one you linked to because it has a larger filter basket. More coffee, better infusion. I make mine with one by Teavana which has a similar sized filter. I basically fill it with grounds, infuse for 36 hours and dilute with ice and cream. Mush smoother than hot brewed c off. No bitterness.
