HDPM,
What a dumb question. Both, of course!
I have just gotten started on brandy in the last couple of years. I have a few cognacs and armagnacs and have tried a bunch more, but I can't offer much opinion/advice on the stuff besides buying whatever the folks at K&L recommend to me and really enjoying it all so far!
Which Old Potrero did you get? Might be different from what you had before. They currently offer three ryes:
100 Proof Hotaling -

Those links describe the different types of barrels/aging used for the releases.
