Drink iced coffee when it's at its best and freshest with Coil. Up until now, to get iced coffee you had to either water it down using ice, or plan a day in advance by soaking the grounds. With Coil, just pour the hot coffee into the lid or brew it directly into the container. The coffee passes through copper tubing — which can drop the temperature from 210° to 48° in under 4 minutes. Instant gratification and your iced coffee never even touches ice.
