Sí, sí Steve...... en el río bajo la sombra de un árbol de mezquite grande una cerveza con una seniorita exprimir mi lime.
How it ever came about that people would ruin a carefully crafted lager with a nasty ol lemon or lime is probably gone forever. That thing with the citrus was because we Gringos didn't trust the sterility of the bottling process. (Montezuma's Revenge, et. al)
So those of us with weak stomachs, (you know them as two beer people) took to swiping the necks with bar garnish, (citrus) to kill any bacteria on the bottle neck. It is a known fact that harmful bacteria will not survive in beer. The Mexicans of course never understood this, only that for some reason we needed a wedge with the cerveza, and so began serving them that way.
Sometime around 1981, some Yuppies from So Cal (that is a State in California) saw waiters delivering beers with limes shoved in the necks at those posh Baja resorts situated amongst the hovels and poverty there.
Not unlike the raccoon's fascination with shiny objects as a way of ensnaring them, these Yupsters ended up accidently poking the citrus all the way down the neck, looked sheepishly around, and said, "I meant to do that."
Now days, we seem to think a lager from Mexico, (probably brewed in Latrobe, PA) "requires" that fruit down there. It doesn't. However any good brewer knows that clear glass destroys lager and ale quicker than an imaginary Mexican Microbe.
