I do like Taylor Tawny as well. Good stuff.
Here are some notes from a tasting we did a few months ago.
100 Years of N.V. Taylor Fladgate Porto Tawny (Douro) – Cellartracker avg prices. Very educational flight. The obvious breakpoint to me in the complexity curve was at 30yr. In checking retail prices after the fact, I didn't find a monumental leap in quality from 20 yr to 30 yr (or 40) to justify 2.5-3x increase in pricing.
10 Year Old ($25): Mixture of raisiny and very ripe fruit, a bit thin and hot but acceptable for a young tawny.
20 Year Old ($45): So much more richness and balance in this port compared to 10yr old. The flavors really linger, some caramel notes, some red fruit, and the heat is tamed. Worth buying for the price
30 Year Old ($108): More unctuous than 20 yr old with an added complexity of walnut skins and macerated cherries. This is more complex than 20 but I’m not sure I like it more. Not worth $100+ for my tastes.
40 Year Old ($126): Not at all that different from the 30 yr. Ya, it is subtly smoother with less perceived heat but I don’t sense more complexity. So not worth the price for me.
