Simply pour a measure of the whisky into your glass. Taking the glass by the stem or base, hold your nose inside the aperture (the opening at the top) and inhale gently.
(A connoisseur will use a special kind of glass for ‘nosing’ a whisky, called a ‘snifter’. It is a glass with a stem, where the aperture is narrower than the bowl in which the whisky lies. This serves to concentrate the vapour and make the aroma more intense.)
Now take a sip. ‘Savour the flavour’ by taking your time and allowing the whisky to roll over your palate for a good ten seconds, before allowing it to slip smoothly down.
