I was into drinking good Port until about 5 or 6 years ago when I started having a problem with the sulfites that are in wines. Taylor, Dow, Graham, Sandeman and Cockburn are all good ports. Warre's are also good.
it really is.I looked up the San Sebastian Port from your link, on Vivino and it scored an impressive 4.2 stars out of 5, which is pretty good for a bottle that costs $19.99.
