You know what? The Berserk and Cranbacco are probably fine (even for a flavor junkie like me) without that extra flavor shot. And as they age, they just keep getting better and better!
Thank you, Ted!
Maybe I should note on the site which flavors are not recommended to get "extra flavor"
For example, I cringe when anything with honey has extra flavor because too much ruins it! It's very touchy.... As are some other flavorings.
