I tried to harvest yeast from some Saison DuPont but it didn't take off (not the topic of this thread). Which is fine, I'd like to try 3711 anyway. But my LHBS only carries White Labs. There's a homebrew shop about an hour and a half away that has a pack of 3711 but it's a year old, so he offered it to me for free. Before I drive that far (I'd make a work-trip out of it too), what do you think are the chances that it's still good?
