People Are Just Realizing the Lid Hats on Tequila Bottles Have a Function On 5/27/21 at 7:07 AM EDT There's a time and a place for tequila shots, which is usually 2 a.m. in a dimly lit room somewhere. Despite drinking the spirit for years, some alcohol fans have only just discovered the lids of the Sierra tequila bottles, which come in the shape of hats, serve an actual purpose. Nino Purtseladze, who calls herself realrijaxa online, shared a video on Wednesday that has already been watched more than three million times, after finally realizing the hats are more than just decorative.
