Bottled beer, taproom sales only, bottles never leave premises--label required?

[uptown brothers]

We want to do a bottle conditioned Brett beer, aged in 335 ml bottles for 6 months then served only in the brewery tap room. Bottles never leave the tap room, in fact customers would never touch the bottle; we would open and pour into glass on order.

Do we still need to label the bottles?

Depends on your state?

The TTB won't care since you aren't going across state lines with it, but every state is different...
