Ninkasi does good work. Though I still lament the loss of their artsy series of lagers and more classic styles.
Old Rasputin is good. Not too dark (from the persepcive of bitter patent malts being used heavy-handed... its got a good well-rounded flavor and takes the bourbon barrel well.
My favorite bourbon aged is the old Allegash Curieaux (sp?)... its been a long while since I've tippled one and always remember those fondly.
