Episode #102: O’Sullivan Bros. Brewing


It was not planned, but our 102nd episode features the brewery that Kyle Wiskerchen used to work at before Division 23.  We are recording this episode with Ed O’Sullivan from his name sake, O’Sullivan Bros. Brewing.  We were very surprised and excited to learn that Ed and his crew are very scientific focused and don’t brew your standard San Diego style beers.


Seeing how Ed’s namesake is in the brewery name, we ask him where he got his knowledge from.  He went through one of the first UCSD Extension program for brewing.  He is now also an instructor with that program.  Ed moves into talking about his brewhouse.  He ended up getting it from Brewmation which partners with Stout Tanks and Kettles.  We find out that they brew mainly malty beers, but there is an IPA on tap.  Ed talks about the ownership structure of the brewery and all his brothers (and sister.)  Before the show we saw he has a lab so Brian is very interested in how he treats his water.  From there Ed talks about the rest of the equipment in the lab which starts with the ability to do yeast cell counts.  Another surprising aspect of the brewery, is they foam down the brewery every 30 days with acid to wash the breweries.  Finally, the lab helps they tracks the gravity of the beers and they plot it for reference.

After a break we come back some listener beer and a talk about the Reinheitsgebot and how O’Sullivan Bros. follows it.  We move into a listener question from Hauck Architecture about why the brew English style beers.  We then get into our news and other topics.
