Whiskey being poured into a glass with ice
This Is How Whiskey Was Served In The 18th Century
In the 17th and 18th centuries, before the rock or lowball glass was invented, whiskey was served in a quaich, a traditional drinking vessel invented in Scotland.
A quaich was meant for enjoying special drinks like brandy or whiskey. Unlike modern glasses and cups of today, quaichs have two handles or lugs (the Scottish word for ears).
The communal aspect of drinking from a quaich added social enjoyment. Since both hands were needed to hold a quaich and drink from it, this vessel built trust and comradery.
