24 hours? Do you have the 8 cup? I have the 8 cup and it takes about 2 and 1/2 to 3 hours. Just keep the filter clean- after every few times I've been puro-caffing mine. Always wash out the whole thing before and after. My problems have been with water/ice ratio, I can't figure out how much to put in so that I don't have to refill it later. Super great cold press though- I've been experimenting with single origins and coming up with some awesome stuff.
Would it be compatible with the popular Toddy Cold Brew system? I think the cotton filter for those brewers are only 2 inches in diameter.
It sounds verrrrrrry nice!
