Perhaps what you are smelling is the beer brewing. It's always been fine when I have been there.
You were probably there when they were brewing are you were smelling the hops and grains. The brewery is awesome and the beers are the best in the state.
Not sure what you think is a funny smell. They do brew beer on site and it's most likely the smell of hops and grain brewing, hence being a brewery. The place is worth every bit of the 5 stars.
They have 5 starts because the place is really cool to hang out in and yeah, you probably were there during the brewing process.
