Don’t screwcaps avoid flavour scalping that occurs under cork and synthetic closures?
Winemakers and researchers are still learning about the interactions between the wine and the closure, including the ability of the closure to absorb certain flavour compounds from wine.
At this stage it appears that synthetic closures have the greatest tendency to scalp flavours, whereas screwcaps scalp little if any flavour. Cork appears to lie somewhere in between.
It may be that in some cases the ability to modify flavour has a beneficial effect, for example in modifying high concentrations of TDN, which imparts a kerosene-like flavour to Riesling.
Some researchers also claim that cork has the ability to remove sulphide compounds from wine, but this is unproven.
What are the ideal growing conditions for the cork oak?
The cork oak is native to the Western Mediterranean Basin, where there are ideal growing conditions:
- Sandy, chalk-free soils with low nitrogen and phosphorus, high potassium and a pH from 4.8 to 7.0;
- Rainfall from 400-800 mm per year;
- Temperature from -5º C to 40º C;
- Altitude from 100-300 m.
A toast to cork!
