Okay, bear with me...

It'd called Guerilla Sommelier, not Nerdy Web Designer. 

We didn't have any computers on La Granma in 1959.

But here is a better explanation of the rating system:

Five Hammers= Epic.  Like watching Batista take off from Cuba in a low-flying plane at midnight.

Four Hammers= Hammer Time.  A great finish at a great price.

Three Hammers= You got your money's worth.

Two Hammers= Something was "off."  Probably priced too high or illogically (See: a future post on restaurant pricing.)  Could have been bad notes in the finish.  Maybe worth another shot.  But there are so many "FOURS"--and life is short.

One Hammer= Save your dinero, Vaquero!
