I used to make them with Harp or Bass under Guinness and now I use Smithwicks on the bottom . However though I will be getting some Boddingtons to try this out with Guinness as both come in pints . Bass would probably be the the original as I have a brass Bass brolly for pouring the Black and Tans with . Bass Ale is embossed right in the brolly and it was free over the internet a while back .
