This is a hard one. Definitely good port casking there but unfortunately it really isn't balanced with the alcohol which overpowers the cask with it's strength and slight harshness. It's only 46% but comes across several % higher at least and definitely cleared out and sanitised my nasal passages when I took a wiff. Towards the end I started getting into it more so maybe if i worked my way through a bottle it might gell a bit more. Definitely a 3.5 as its only $60USD but unfortunately I had the 1977 portwood shortly after and in comparing to that it was hard to round up to a 4.
