Bad hair days for wine

At this stage, there's something I need to tell you. It adds another level of complexity to wine tasting, but we can't ignore it.

It's the fact that wines show differently on different days. It's not clear why, but the same bottle opened on a Tuesday might taste different to the same bottle opened on Friday. It's known in the trade as 'bad hair days' for wine. Well, actually, it isn't but it should be. I've only heard the phrase mentioned once, by winewriter Simon Woods (pictured), and I like it.

What's the explanation? I can think of several. First, it could be that we change from day to day in our ability to taste. It could be our hormones; it could be our mood; it could be whether we have the beginnings of a cold; or it could be the other wines we've just tasted, or food we've recently eaten, that have affected our palate.

Context could matter: where and when we are tasting the wine.

Atmospheric pressure may have an effect - wines could taste better on bright days with high pressure than they do on cloudy, low-pressure days. Ambient temperature and humidity are likely to factor here, too.

And there's also the biodynamic calendar. Stop sniggering at the back: some UK supermarkets actually schedule their press tastings to take into account whether it is a shoot day or a root day. I'm not sure which is best.

The long and short of it is that experienced people in the trade think that there's something real about the fact that wines have these 'bad hair days', although personally I suspect this explanation is marshalled more often for wines with the 'right' labels than it is for humble wines.

I score this the surprise of the day.

This topic is something that's bugged me for quite a while - wines seeming to show better on one day than another. Even whole tastings.

So, I like what you have here, and, I think this has to be a solvable mystery...right?

I'm having a hard time making the leap that Lunar cycles could affect taste, though.

I've always put this down to minor cork variations. Does this still occur with other closures?

Anyone who has tasted wine blind for years well understands "bad hair days for wine ". What I find remarkable is how many experienced palates look for exotic explanations like (bottle variation,cork variation,wine needs to breath,TCA, phases of the moon etc etc) While it is important to accept the fact that these possibilities do exist and can be pertinent the explanation is often within the taster and not external. We have an amazingly complex olifactary system which is contantly recalibrating i.e. the perceptual differences are often within us
