Best for me? Definitely not cheapest. . . First I looked around and found the Snow Peak Ti French Press, that's what I will use as a container for the truck coffee kit. Next I will pick up some non-ground coffee beans. Next I will need a decent hand grinder that can do a consistent coarse grind. . . any suggestions? Grind them too soon and they oxidize, and then the flavor is flat. . . Does smashing beans get a consistent grind? Either than or I use a knife and just cut them. . . too slow. A 12 volt grinder would be great. . .
