My hosts at last night's signing at Philadelphia's Indy Hall co-working space did a lot to make me welcome, but most of all, they supplied me with rocket-fuel. The fuel took the form of a bottle of La Colombe Pure Black Cold Brew, a deceptively smooth, dark, chocolately cold-brew coffee that comes in a 12oz beer bottle. Deceptively smooth because this stuff is, as noted, pure rocket-fuel. They gave me a bottle for the road that I cracked in my hotel room this morning before heading to DC, and it practically had me plastered to the ceiling, despite its mellow flavor, and in a very good way.
I drink a lot of cold-brew on the road (I use the radical hotel-room coffee independence method to make cold-brew in breast-milk bags that I put in the minibar fridge overnight) but La Colombe was a cut above even the excellent stuff I make myself.
