Q:

An age old question (pun intended) came up again about the labeling of Tawny ports while enjoying a bottle of Grahams 20 Year Old Tawny.  While common convention dictates that the age of the tawny indicates the average age of the wines in the bottle, my understanding is that current IVDP laws regulate that as long as the wine subjectively taste like a particular age characteristic the bottle can be labeled as such.  Is my understanding correct that a majority of port houses actually adhere to the IVDP interpretation and not what common sense dictates?

Q:

Have there ever been attempts at creating grape-specific ports such as a single quinta Touriga Nacional for instance? I imagine it could be interesting for port enthusiasts to compare two single-grape ports from the same vintage.

Q:

I bought a bottle of WARRE'S 20 yr old TAWNY PORT and it was bottled in 2002. May i check with you what is its 'age' actually? Is it a good Vintage?  How long can i keep it?  Thank you.

Q:

Is each lote (batch of wine) of  Port laid down at harvest for a particular house within the Symington group or is there any flexibility to put (e.g.) something from the Dow cellar into a Graham tawny if it would better suit that style?
