Most people picture one glass when they hear “stout glass”: the branded pint used by Guinness (we also reviewed Guinness Draught itself, if you want to know how it actually tastes). That is a fair starting point, since Guinness alone accounts for the vast majority of stout served worldwide, but it is not the only shape in use, and Guinness itself has changed its standard glass more than once. If you are buying stout glasses for home, it is worth knowing what each shape is actually doing before picking one.
The tulip pub glass, the industry default
Guinness’s standard glass for decades has been a 20oz “tulip” shape, wide at the top, tapering inward about halfway down, with a flat, stable base. The taper is not just aesthetic. It funnels the nitrogen-driven surge that gives stout its signature cascading pour, and it helps concentrate the creamy head at the top of the glass rather than letting it spread thin. The same basic shape has appeared under various brand labels over the decades, harp logo, toucan mascot, the old “My Goodness My Guinness” branding, but the core geometry stayed consistent.
“The gravity glass was designed so the nitrogen bubbles cascade down the sides and rise up through the center, building that dome on top the classic tulip couldn’t quite do the same way.”, Ryan Wagner, Guinness Open Gate Brewery ambassador
The gravity glass: Guinness’s 2010 redesign
In 2010, Guinness introduced a second official shape called the “gravity” glass: taller and slimmer than the classic tulip, with a much less dramatic taper. According to Guinness Open Gate Brewery ambassador Ryan Wagner, the redesign was meant to change how nitrogen bubbles move through the pour, encouraging them to cascade down the sides of the glass and rise back up through the center, building the dome-shaped head that has become part of the brand’s visual identity. Not every longtime drinker preferred the change; plenty of fans still ask for the original tulip specifically, and both shapes remain in circulation at different bars.
Stout glass shapes compared
| Glass | Volume | Shape | Best for |
|---|---|---|---|
| Tulip pint (classic) | 20oz | Wide top, tapers halfway, flat base | The traditional Guinness shape, still the most common worldwide |
| Gravity glass | 20oz | Taller, slimmer, gentler taper | Guinness’s 2010 redesign for a different nitrogen cascade pattern |
| Stem/snifter-style stout glass | About 14oz | Rounded bottom, widest at base, branded as a ‘half-pint’ | Used for stronger imperial stouts served in smaller pours |
| Nonic pint | 20oz (imperial) | Straight sides with a bulge near the rim | Standard British pub glass, sometimes used for stout though not stout-specific |
Smaller stem glasses for imperial stout
Stronger stouts, imperial and Russian imperial versions that can run 8 to 12 percent ABV, are typically served in smaller stemmed glasses, often branded as a “half-pint” even though the actual capacity is closer to 14oz. These glasses have a rounded bottom and are widest at the base, a shape closer to a snifter than a pint glass, meant to concentrate aroma for a beer you are sipping slowly rather than drinking a full pint of in one sitting.
Stout Beer Glass: Quick Facts

| Alternative shape | Gravity glass, introduced 2010, taller and slimmer |
| Nitrogen delivery at home | Widget-equipped cans or Guinness NITROSURGE device |

What to actually buy
For everyday stout at home, whether Guinness, Murphy’s, or one of the craft dry stouts on our dark beer brands list, an official branded pint glass is the safest, most tested option since it is designed specifically around the nitro pour. If your collection needs to cover both a session-strength dry stout and an occasional imperial stout, pair a standard pint glass with a smaller stemmed snifter for the stronger stuff rather than trying to make one glass do both jobs.
FAQs
What glass should I use for Guinness at home?
A standard 20oz tulip pint, the classic branded Guinness shape, is the safest choice since the glass’s taper is built around how nitrogen-poured stout cascades and forms its head.
What is the difference between the tulip and gravity Guinness glass?
The tulip is Guinness’s original shape, wide at top and tapering halfway down. The gravity glass, introduced in 2010, is taller and slimmer with a gentler taper, designed to change how the nitrogen bubbles cascade during the pour.
Do you need a special glass for canned nitro stout?
Not strictly, but a proper pint glass helps the widget-driven surge form a fuller head. The widget inside the can forces nitrogen through a small hole when the can opens, recreating a draft-style pour regardless of glass, though a tapered pint glass shows it off best.
What glass is best for imperial stout?
A smaller stemmed snifter-style glass, around 14oz, works better than a full pint glass for imperial stouts in the 8 to 12 percent ABV range, since it concentrates aroma for a beer meant to be sipped rather than drunk quickly.
