It's been a long time for reliable distro to Folsom, a few months back found bottles near Rancho Murieta. Road trip to SR is only definite way to obtain Pliny. Total Wine sez they get a case first Wed. of every month and limit to 1 PP but never personally got it there.
Only if you have a time machine. If you do, set your dials for 2008 and you can find it at any number of places. These days, every place that gets it sells out within hours, so there's no "reliable" source.
I got a bottle at Corti Bros the other day, what a pleasant surprise. Did a blind taste test with Enjoy By, and I was surprised at how much obviously better Pliny was. I thought it'd be closer.
Had one last night, got it from the brewery. Better off going up once in a while and just bring back plenty of bottles.
