Pliny the Elder in Philadelphia

Very True. Unfortunately, just not right at the moment (was there last night and it was not on tap).

 

I'm assuming things haven't changed a great deal when it comes to the obtainment of RR beer, since I last lived in the Mid Atlantic region (back in 2012, when the OP's question - or one's very similar to it - came up on a pretty regular basis).

My understanding is that Origlio receives a shipment of RR product once a month. Upon receiving their current shipment, they then go about the business of filling order requests, which includes filling orders for PtE. In my experience, for roughly a week after that, one can find PtE in a variety of Philly/SEPA bars and pubs. Unless a pub/bar plans to hold onto a keg for some special event (DIPA/IPA tasting; anniversary party, etc.), most places tap their keg of PtE within a few days of receiving it (as the beer is best when fresh, and so no purpose is served by holding onto it). The rest of the month, it's not all that easy to find PtE in the area. I've heard/read that Monk's gets several kegs of PtE each month, which is why they seem to have it on tap a bit more often than other places in town. I'm not sure about Teresa's Next Door, but have often noticed that they seem to be better supplied with RR beer than most other places in the SEPA area (for instance, while they didn't have any PtE on tap last night, if memory serves, they did have on a keg of redemption and Salvation).
