For The Love Of Port

Before discovering this site, VP was something I never drank on my own. - Consequently, with thirsty company, bottles rarely lasted more than an evening!

The opportunity to share the experiance, blow by blow, not only allows me to guzzle the whole of a fine bottle without conscience, but has also alerted me to the evolution that takes place after decanting.

That respected commentators base their judgements on my bottles that have scarecly had time to breath after decanting is telling...

From my recent experiance I observe that:

a) Wines of modest age (under 40 years) often continue to improve after 24 hours decanting. Some that are very uncivilised after 3 or 4 hours can improve enormously.

b) None has been noticeably in decline after 36 hours.

Until I have an experiance to change my mind; when preparing for a dinner party, I will now be decanting all but the oldest wines the evening before.

- Just my two penneth!

Not much difference of opinion here - more one of degree.

Perhaps a significant detail is that I don't let my decanters warm up - I keep them "cellar cool" throughout.

Is temperature the cause of the myth that vintage port needs to be drunk within 2-3 hours?

I wonder...

To be honest Tom, I had never heard nor read that anywhere before now.

Has anyone, ever, looked at this scientifically??

Tom

I do not believe so, at least I should say, I have never seen it written up anywhere.

Makes sense: Heat will increase the molecular speed which will increase the rate of oxidation. If I have the time for a long decant, I decant in the cellar. :)

Not just the rate of oxidation - heat has a significant effect on taste also - warm port tastes spiritous and unsophisticated.

I wonder if there is an ongoing chemical reaction stemming from the intitial exposure of the wine to air when decanted - or a progressive reaction from it's continued exposure thereafter.

In the second instance, the shape of the decanter would be significant, in the first, it might be possible to get some interesting results if the decanter was flushed with a neutral gas like nitrogen or argon prior to decanting...

What is the point in doing that :?

It would greatly reduce the wine's exposure to oxygen during the decanting process.

This might give the wine a very long shelf life in the decanter, but it might also reveal whether some oxygenation is necessary for a wine to show its best.

OK now I understand what you are trying to achive. Why not use Roy's method for filtering but skip the decanter. Instead place the funnel directly into another bottle or (if you want even less exposure to air) directly into a food grade expandable plastic bladder such as you find in a hydration system ("Camelback" or the like) ?
