Red wine should be served at room temperature, referring to European temperature (which is completely different to SA, especially in summer). Therefore, to preserve the red wine, theres no need being afraid to dunk it into an ice bucket to tighten up the flavours.
Wine served too cold will inhibit the fruit characters, which makes it far more acidic. The general rule for young red is to serve it cooler than rich styles, and dry white wine shouldn’t be as cold as sweet whites.
So next time you crack open a bottle, experiment and see how different temperatures affect the flavour.
