Nucleated Pint Glasses
It is increasingly common to find pint glasses which contain markings on the base; very often these glasses are branded to one particular beer. The markings themselves are formed from small pits which aid in nucleation, allowing the gas within it to be released more easily, thus preserving the head. Without the aid of these pits a regular pint glass will keep a head for only 3 or 4 minutes before appearing 'flat'. The markings come in a variety of styles ranging from a simple circular or square hatched pattern to more complicated branding messages.

“Nothing in Nature’s sober found,
But an eternal health goes round.

Fill all the glasses there—for why
Should every creature drink but I?
Why, man of morals, tell me why?”
