Alcohol levels in wine – high or low?

Alcohol levels in wine have increased significantly over the past 20 years. That is not to everyone’s taste, but are low and zero alcohol wines worth considering?

Why have alcohol levels increased?
There are several proposed reasons, including:-

  • Climate change – more heat and sunshine produces riper grapes with more sugar, and hence more alcohol.
  • Better practice in the vineyard, producing better quality grapes, with higher sugar levels.
  • The influence of certain wine critics, which encourages big wines with high alcohol levels.

What influence does alcohol have on your palate?
Alcohol stimulates nerve endings in the mouth, to provide a sensation of body and texture. It spreads flavours around the mouth, which persist even after the wine has been swallowed – known as the ‘aftertaste’. If the alcohol is too high, and is not balanced by the fruit, then the aftertaste may be bitter. If the alcohol is too low, then the wine is thin and unappealing.

Lower alcohol wines
The most successful lower alcohol wines (less than 10%) are those made in Germany. The fermentation is stopped short, and the wine may be sweetened by adding unfermented grape juice. This combination of lower alcohol, sugar and good acidity works very well indeed.

How low and zero alcohol wines are made
A wine has to be made by fermentation of grapes; this produces mainly alcohol, but also a host of other chemicals which contribute to a wine’s taste and smell. So the alcohol needs to be stripped out, but this is likely to remove other compounds as well.

Why drink very low or zero alcohol ‘wine’?
For the reasons stated, these ‘wines’ are a mere shadow of their former selves. So why not drink unfermented fruit juice instead?

Suggestions if you are worried about alcohol consumption:-

  • Look for wines from cooler regions of the world, which will have lower alcohol levels.
  • Drink less.
  • Add water to high alcohol wines. I know this may be sacrilege, but it is better than commercially stripping out the alcohol. Please don’t add fizzy drinks unless you hate the wine, as this completely disguises what you are drinking.
