I have had both several times. Let me put it this way...
Where Artemis will curl your toes, Fay will have you seeing fireworks..
In other words, both wines are amazing, but the Fay is beyond amazing!!
Artemis is a blend of different cabernets, some of which is made from outsourced grapes. Fay is made from grapes that are 100% grown in their Fay vineyard. This is reflected in the price. Where a good price for Artemis is around $40.00, a Fay is around $100.00.
I know what you are thinking.. Is it worth the extra $60.00?
IMHO, YES, YES, YES! from the balance to the complexity to the concentration of flavors to the incredible finish, this wine is worth the extra money!
I am not talking about drinking this every day. Lord knows that I do not have that kind of money, but you owe it to yourself to be treated to something truly grand!
