The term “growler” can be traced as far back as 1883.
Rumor has it the name comes from the sound of a full jug as it was shoved down the bar by a bartender.
Another suggests the term “growler” stems from the amount of beer given to workers to prevent their stomachs from growling with hunger.
Some even say that “growler” is meant to describe the grumpiness of someone who drank the entire container.
