A little more than a year ago, on 10/27/12 to be exact, I wrote the following the following footnote about iced coffee.
It’s worth noting the difference between iced coffee and chilled coffee. Iced coffee (as the name suggests) is coffee with ice. It may be convenient, but the ice ends up diluting and weakening the coffee. Chilled coffee (sometimes known as cold coffee) is brewed coffee that’s been put in a fridge. I like to cover, but not seal the coffee, as it allows some carbon-dioxide to escape while retaining aromas. No footnote about chilled coffee would be complete without mentioning cold brew. By adding ground coffee to a mason jar filled with water, and leaving it in the fridge for 24 hours and pouring through a filter, a coffee concentrate is created that ice can be added to for true “iced coffee”.
In my post yesterday about Demitasse, I wrote a paragraph about Kyoto drip, but failed to categorize it. Kyoto drip is not iced coffee because it is not brewed, and is not poured over ice . Kyoto drip is not chilled coffee because a): it is not brewed, and b): it does not have to be put in the fridge. This brings me to my point I failed to make clear. Kyoto drip does not have to be chilled. This is because Kyoto drip is more similar to cold brew, the third type of “cold” 
coffee I mentioned. Both are essentially a coffee concentrate, but cold brew is simply kept in contact with the grounds for 24 hours, whereas Kyoto drip is slowly filtered through the grounds. Also, I was wrong in calling cold brew “true iced coffee”. Like Kyoto, it does not have to be served cold, but rather labeling it as “cold” coffee is more convenient. Kyoto drip is a category of its own, and should not be confused with iced, chilled, or cold brew coffee.
1. If a Kyoto drip is ordered to-go at Demitasse, it is served over ice. When consumed in-store, the Kyoto drip is served in a decanter that separates the ice from the coffee. I called Demitasse, and asked them why a to-go order is served over ice. They explained that traditionally it should be served separated from ice, but a to-go cup does not have the capacity to do this. Furthermore, I was told that you can ask for a to-go Kyoto without ice. I think they should ask if you would like it with ice, as most people would never consider drinking “cold” coffee without ice.
2. This is just a term I am using to describe all coffee that is not hot.
