I’ve discovered my kryptonite. I can see kitchen gadgets, drinkware, tools and any number of other items on the shelf but if their use is obvious I can ignore them. At a recent trip through Williams Sonoma I wandered near the barware and nestled among the cocktail shakers and bottle openers was this simple coaster sized piece of steel. It was sold unboxed, with neither instructions nor explanation. The sole concession to marketing was the engraving around the edge promising the “Perfect Black and Tan”.
It was $9.95 and I was hooked. From the photo it appears to be slightly flat but this could not be further from the truth. The outer ring is designed to sit comfortably around the rim of a pint glass and leaves enough space for a collins or a slightly wider than normal bar glass. The middle ring is recessed from the rim and has equally spaced holes in the bottom of the depression.
The center is a raised dome of steel, perfectly rounded. Being of a single piece of steel there are no welds, seams or rough edges.
Not being a beer drinker I was not immediately familiar with the Black and Tan as a beverage. If you are (like me) unknown to this drink it is a combination of lager and stout most notably Guinness and Harp. Porter and pale ale are also allowable but the original is as given. The drink is supposed to be served in a pint with a relatively clear separation between the two beers. A “Perfect” black and tan would have a firm line between the two without blending between. The Guinness is usually presented on top despite the arguably higher specific gravity (thickness).
To achieve this process the bartender will pour the Guinness over the back of a bar spoon or down the angled edge of the glass to slow the beer’s fall. This is the same process would would use to create a Pousse Cafe only simpler because you’re using only one layer.
So the intent with this little gadget is to give you a bar spoon like surface to spread out the overall pour and prevent splashing and then allow it to drain evenly through the holes across the surface of the lager preventing a single point of contact from mixing the two beers.
This is a fantastic design and a well thought out item. It is easy to clean, use and store. Beyond those elements it is useful for more than simply the original intention. You could use this item to create similar separated drinks in any other format so long as the glass allows for the drain openings.
I have not attempted an actual pousse cafe with this as most of them use significantly smaller quantities of alcohol and much smaller glasses.
