Most vintages are made in giant stainless vats and all vintages are bottled after a year and they age in the bottle.
Unlike malt whisky, which relies on flavour imparted from the barrel, port is all about the grape.
You don't want any other flavours in the port so they only use a barrel once then sell them to whisky makers who love the depth of taste they get from them.
The bourbon tours made clear that all the coloring & much of the flavor came from the charred barrels. Why barrel it at all for only a year? Just dump some oak chips in the vat like the cheaper Chardonnay makers do.
Why barrel the port for just a year?
The method for making port or any other fortified wine is to add distilled wine (brandy) to it.
Port is made by blending wine which is from the previous season with a spirit distilled from the same wine. The brandy is added at 76% when the wine is still fermenting the sugars contained in the grapes.
This boosts the wine to 20% which kills the yeast and stops the fermentation. The unfermented sugars are what gives port its sweetness.
The reason you have to store it for a year in vats or barrels is to allow the sediment (mostly dead yeast) to settle and give it time to clear.
Vintage port is then bottled and stored for about 20 years to mature. The best vintages will peak at around 30-35 years with exceptional years staying good for 50 years.
During this time the port will lose a lot of its deep red colour and become much paler.
The bottles contain sediment and have to be stood upright for several days and then carefully opened and decanted leaving the sediment in the bottle.
Tawny port is different from vintage because it is matured in oak and the resultant oxidation and evaporation turn it golden brown and give it a nutty flavour. It is then blended and the result is a paler and less sweet port.
Late bottled vintage is stored in large neutral vats (stainless or plastic) for longer than vintage. usually 7 years in the vat. This means that the port is ready to drink as soon as it is bottled but unlike vintage it won't improve in the bottle.
LBV is the cheaper alternative and it has the advantage of not needing to be decanted. It still has to be declared a vintage year that the grapes were grown but the different technique results in an inferior port.
I bet you wish you'd never asked now.
I can bore people for hours on the subject of port.
I love the Britishness (despite being made in Portugal 70% of all port is consumed in Britain and all but one of the major port houses is British owned, Sandeman being the exception) and ritual of it all. Plus the fact it is delicious.
