I wonder if any of them have experimented with cold brew yet. Personally, my preference is Funranium Labs' (http://www.funraniumlabs.com http://www.funraniumlabs.com) Black Blood of The Earth (BBoTE). The upside is that you don't need to carry around alot of apparatus: You can get a good Americano equivalent with 3:1 or 4:1 BBoTE to hot water. Or you can have it straight. One downside is that it's supposed to be stored cold; but it can handle 2 days of room-temperature (considering how it is shipped), so maybe it's not too big of an issue. Another downside is most of the BBoTE offerings are single-origin, so things go out of stock from time to time, but there are some blends available: Death Wish is one, and the proprietor has been known to do custom batches of Dunkin Donuts and other blends.
