Glencairn glass is popular among single malt connoisseurs who drink Whisky neat or with a drop of water.
It’s a perfectly crafted drinking vessel that combines both form and function to deliver the ultimate tasting experience. It's used in most Whisky labs as it is engineered to bring the richness of aromas and flavors so that you can notice every tiny nuance.
There is some preference towards tulip-shaped glasses that concentrate Whisky aroma towards your nose. They're also neat for swirling.
Generally, a simple glass with a wide brim ideal for nosing is a safe bet.
Glass's shape and quality make some difference, but at the end of the day, the real business had happened in the barrel, so don't make too big of a deal about the glass.
The crafted complexity of Whisky production renders Whisky drinking a simple pleasure.
