Been going down the list of ports available at a local supermarket. Starting with cheapest with label indicating certified port from Portugal. So far 5 bottles. Mostly Sandeman and Graham's. Ruby, Fine Tawny, Fine Ruby, Reserved Ruby. LBV are not available at the supermarket, but we do have wine stores. It seems price start going up with 10 year old. Few more bottles to sample at local place. Six Grapes, 10 yr old tawny both from Graham's. There are small vineyard bottles at rather good prices for vintage ports. Not exactly the best years. '97, '98, and some early 2000. Mail order only.
Tawny port is a good starting point as bottles can be finished over a couple of weeks, whereas vintage ports and LBVs should be drunk within a couple of days of opening.
10 yr old tawnys are to be had at reasonable prices. The 20 yr olds are my favourites as they still retain quite a bit of their primary fruit, while displaying mature character.
Ready to drink upon purchase.
A vintage is "declared" when the quality of the harvest is very good to excellent.
When the vintage is good, rather than very good, a house may direct their better grapes into a LBV - which gives rise to releases in "undeclared" or lesser vintages.
These LBVs can be excellent value as they contain juice usually reserved for vintage ports. Like their vintage brothers they will mature further if cellared
Ruby ports are younger versions of tawny. So called because more of the primary red colour is still present in the wine.
As port ages, the colouring pigments coalesce, drop out of solution and form sediment. With time this sediment forms a "crust". Crusted port is a term that is still seen occasionally on some bottlings.
You should decant bottles of old(er) ports.
