Quick question for anyone who can answer it:

I'm a head brewer at a small farm brewery in Virginia who is in the process of starting my own. I'm currently searching for the right location but would love to do a couple of brews with some friends of mine while I wait. Is this possible without my TTB Permit? This would be a great way for me to make some extra income and establish my brand within the state. I am a registered LLC. A few of the breweries I'd like to work with are within the state and one is in NC. Any advice would be greatly appreciated.

Thanks
