I think it was partly in jest, but in truth, some of the wineries that make these so-called “higher-end cuvees” do in fact spoof them with more than just megapurple. For example, some change their regular oak regime, use more or all new oak, oak longer. Etc. Granted, I suspect that the First Growths likely all use predominantly new oak. At least that’s the way I use the term, “spoof,” an exaggerated or overly-manipulated bottling.
One of my favorite wineries, Sociando Mallet, made a special cuvee that is actually damn nice:
Chateau Sociando Mallet, Cuvee Jean Gautreau
in 1995, Sociando Mallet produced a special wine that was at the time, intended to only be produced in that one vintage, Sociando-Mallet Cuvee Jean Gautreau. The wine was made from a barrel selection and was aged in 100% new, French oak barrels. To produce the wine, Jean Gautreau pulled the eighty best barrels from over 1,500 barrels.
Those barrels were aged separately. Then, out of those 80 barrels, Gautreau pulled what he considered the top 15 barrels. Those 300 cases were bottled for his own pleasure and were not originally intended for sale.
