Techniques for Using Mint Leaves in Cocktails

Muddling: Gently press (do not tear) leaves with a muddler to release aromatic oils. Over-muddling brings out bitterness from the stems.
Shaking: Add whole leaves to the shaker for a subtle infusion of mint without overpowering herbal notes.
Garnishing: Slap a mint sprig between your palms before garnishing to express essential oils, then place on top for enhanced scent with each sip.

Bartenders often choose spearmint for its sweet, approachable menthol quality, though peppermint brings an intense, spicier profile. Always use freshly picked, aromatic leaves for best flavor impact.

Tips for Home Bartenders Using Mint

Use only the freshest, unbruised mint for the cleanest flavor; limp or darkening leaves can deliver muddy or bittersweet notes.
Store mint stems in water or wrap in a damp paper towel in the fridge to keep them lively longer.
For sustained aroma, place garnish directly by the straw or drinking edge so each sip is perfumed with mint.
