Do Black and Tans Work in Arizona?

Gerry from Kearny AZ had emailed me with some great feedback about the tool that he had received as a gift from a friend. His input led to putting up the Instructions webpage mentioned a little while ago in the blog. 

Gerry was using Guinness bottles, which is not as easy to layer as the Guinness cans.  After some experimentation he came up with an interesting technique.  Here is Gerry's description: 

"I’ve attached some photos from this weekend when we used your special tool and it worked GREAT! I even have a “close up” of the device causing the top layer to foam, so it floats in the foam on top of the lower layer.  AND we have developed a “trick” to improve the foaming action of the bottled Guinness Stout. When I put the Guinness bottle on the counter, I do it with a bit of “authority” as Cartman might say on “South Park”.  While I’m pouring the Bass into the fluted frozen glasses, the Guinness sits and absorbs the light shock I’ve given it. Then, when I OPEN the bottled Guinness with a standard “church key” aluminum opener, I just barely rock the top to break the seal. There is a tiny “pssst” and then I stop and push the top back DOWN. After about 10 seconds, I begin pouring the Guinness into the Perfect Black and Tan device, and from the photos you can clearly see the foaming action that takes place thanks to your innovative design. It works GREAT!"

Thanks for the feedback Gerry!
