KELLERBIER 6.0% Process and imagination converge in this modern classic. Cellarless Keller is a traditional lager cellared using a new technique to achieve the elegant aromas and flavors of toasted oak barrels without the timely oak conditioning process. Instead, we pioneered the use of oak wood treatments in the beer using a proprietary blend of toasts and char. Our combination of oak woods are specific to our lager recipe and pinpoint a flavor profile to create a genuinely Cellarless Kellerbier.
