Cognac bottles should be stored upright to prevent cork taint.

Cognac is best stored at room temperature.

Immediately after pouring, re-cork the bottle of cognac. Do not leave a bottle of cognac opened for very long - otherwise the contents will evaporate.

Should be served in a glass that fits comfortably in the hand.

Glass should be thin-rimmed; avoid overly narrow glasses or ones that are too deep.

The glass should narrow slightly at the top - this helps to trap aromas and direct them toward the nose.

The glass should be large enough to fill about ¼ capacity

A thin glass is crucial - the delicate aromas can be released slowly through the warmth of the hand.

Just before tasting, rinse the glass out with a drop of the same cognac that is about to be enjoyed. Cognac glasses should be washed in clear, warm water, without detergent.
