Sometimes (only sometimes, maybe half the time) I find it impossible to push the plunger down (and thus pour coffee out of the Press). If I try too hard, coffee gushes out all over the counter or (as just now) I break the entire plunger part.
What causes this to happen?
Can I do anything to prevent it? Or to speed the process along? (Usually, ten minutes or so allows me to pour coffee.
Is this a problem with the press, with the coffee, with me, with the universe?
