I like both tea and coffee but when I tell a coffee drinker putting together a BOB I recommend tea because of the taste of freeze dried. If you like freeze dried or instant coffee use it since you can get it in single serve packs and small jars. The only reason I have tea in my pack is as a moral booster and that’s best done with something you like. I don't know of any other reason and if there is another maybe some one will enlighten us. As far as what kind grab a few of the sampler packs and find your favorite flavor.
