Scrublin Stout

I used an old-fashioned American yeast (ECY 10 - the old Ballantine Ale strain) for my best bitter, and so I figured it would be a nice yeast to use on a dry stout. Since I hadn't brewed a low-gravity dark beer ever, I thought it seemed prudent to try. Here's what I did:

I dubbed this dry Irish-style stout "Scrublin Stout," as the style originates from Dublin, Ireland and Dublin, California is sometimes called Scrublin by residents of nearby San Ramon, CA, where I grew up. I am kegging this stout today.

Edit: It's good and kegged now and it tastes great.
