The majority of brewpubs are all grain brewers. A very small percentage are extract brewers. Some brewpubs do most of their beers all grain, but may do a special or seasonal using extract, often as a trial. The cost of extract and the limitations it places on a brewer in making craft beers makes it unattractive. The level of activity you see in a brewpub and the number of brews they make in a week is related to their sales and the size of their brewing system. The economics of brewing makes it attractive to brew in 7 - 10 barrel batches. If a brewpub has a 10 barrel system, depending on sales, they may only brew 2 -3 days per week or less. And yes, some brewpub chains may brew more beer at one location than another and truck the kegs between pubs. So, not all the beer sold at one location was made at that location. Are there brewpubs out there with the equipment as show, I suspect yes. However, I suspect either the equipment has been bought as a decoration and is not functional or the particular location does not need the capacity at the current time and draws its beer from a functioning brewpub at a near by location.
These are just my observations.
