Cab Sav 15 and the Pike Creek 21 year Oloroso tried side by side. The 15 has a sweeter nose, the 21 is nuttier and bit more dry. Which is better would depend on the drinker’s preference- both are good. I give a slight edge to the 15. The palette is creamier on the 15, balanced and fruity. Very nice. The 21 is a bit better, dry, spicy and delicious. The win goes to the 21 for the longer finish and better overall experience. Both are worth a buy.
