Well, yeah the guy from Shipyard says that they use a multi yeast blend....but all I know is that very distinctive flavor/aroma is in the Shipyard beer and the last 2 I brewed and I am not a big fan. Maybe they add another strain to help finish off the fermentation so that they don't have to shake their fermenters to help rouse the yeast.
Yes, the WLP005 and Wyeast 1187 are the same according to the chart on Mr Malty's website
Monk, I have already brewed, kegged, and served these beers. The published attenuation should have been dead on for all the styles but I came up short on each.
