There is no shortage of things to be learned from wine labels. I must admit that, before seeing Moo Clu, I was without a clue about clurichauns, let alone how to party like one. The label and this site explains that clurichauns are like leprechauns but far more mischievous.
If you treat them well they will protect your wine cellar, however, if mistreated, they will wreak havoc on a home and spoil the wine stock. Occasionally [they] can be heard singing Irish folk songs in the wine cellars. The clurichaun is great to have around the house because he also protects your home from vandals and thieves. … They are impeccably dressed and well-groomed. … Except for a pink tinge about the nose, they perfectly resemble leprechauns in all their physical characteristics, but they never wear an apron or carry a hammer, nor do they have any desire to work.
Moo Clu is honey wine fermented with lactose, hops and natural flavors. Sometimes, it is a fine line among beer, wine and other beverages (such as kombucha, barleywine, etc.). Just as there can be a fine line amongst the various Celtic Fairies.
