What Size Coffee Is 24 oz? A Guide to Large and Venti Servings

3 min read

According to coffee industry standards, 24 oz is often considered an extra-large or grande-sized beverage, although branding varies. For most coffee drinkers, knowing what size coffee is 24 oz can be confusing, especially with the unique sizing systems used by different coffee shop chains. This article will help you understand this common coffee size and its equivalent names at your favorite cafes.

Quick Summary

A 24 oz coffee is most commonly known as a cold 'Venti' at Starbucks or an 'Extra Large' at chains like Dunkin' Donuts, though exact terminology varies. This size is one of the biggest options available, and its caffeine content and liquid volume can differ significantly depending on whether it's a hot or iced beverage. Knowing this helps customers manage caffeine intake and choose wisely.

Key Points

  • Starbucks Venti Iced: A 24 oz coffee is most famously known as a Venti, but only for cold drinks, not hot ones, which are 20 oz.

  • Variable Caffeine Content: A 24 oz cold brew from Starbucks can have significantly more caffeine (310mg) than a standard Venti iced coffee (235mg).

  • Extra Large at Other Cafes: At chains like Tim Horton's, a 24 oz coffee is typically referred to as an 'Extra Large'.

  • Common Tumbler Size: 24 oz is a very popular and common capacity for reusable travel mugs and personal tumblers for on-the-go brewing.

  • Customization is Key: Due to the large volume, customers may need to specify an extra espresso shot to ensure a strong coffee flavor, rather than a diluted, milky drink.

Decoding the 24 oz Coffee Size

For many coffee lovers, a 24 oz beverage represents a significant and satisfying volume, ideal for a morning kickstart or a long work session. However, the name for this size is not universal and can be a point of confusion for consumers navigating different coffee shops. The most famous example is the Starbucks 'Venti' size, which famously changes from 20 oz for hot drinks to 24 oz for iced beverages.

Starbucks' Venti: A tale of two sizes

At Starbucks, the Venti size is a bit of a trickster. The word 'venti' means 'twenty' in Italian, which logically suggests a 20 oz size. This is indeed the case for hot coffee drinks like lattes and americanos. However, to accommodate for ice and provide a more substantial cold beverage, the Venti for iced drinks is 24 oz. This means a customer ordering a Venti Iced Latte receives more liquid volume and, crucially, an extra shot of espresso compared to a hot Venti beverage.

Dunkin' Donuts and other extra-large options

While Starbucks has its own naming convention, other major coffee chains and independent cafes use more straightforward labels. At Dunkin' Donuts, for example, a 24 oz iced coffee is typically referred to as a 'Medium,' while a 'Large' is 32 oz. This highlights the need to check specific menu sizes, as what is considered 'extra-large' at one establishment might be a 'medium' at another. Many independent cafes may also offer a 24 oz option, typically labeled as 'Large' or 'Extra Large'.

Why does size affect taste and caffeine?

The size of a coffee doesn't just impact the volume; it also significantly influences the drink's taste and caffeine level. For espresso-based drinks, a larger size often means more milk and syrup are added for balance, which can dilute the coffee flavor unless extra shots are included. The caffeine content in a 24 oz iced coffee can be considerable, as seen in Starbucks's Venti iced coffee which contains 235mg of caffeine, while a Venti Cold Brew packs an impressive 310mg.

The rise of oversized coffee mugs and tumblers

Beyond cafe-specific sizing, the 24 oz measurement is a common capacity for reusable travel mugs and oversized coffee mugs. For those who prefer to brew at home and take their coffee on the go, a 24 oz insulated tumbler is a popular choice for keeping drinks hot or cold for extended periods. The popularity of these mugs has contributed to the 24 oz size becoming a household standard, moving beyond the traditional cafe context.

Tips for ordering your 24 oz coffee

To ensure you get the perfect 24 oz drink, follow these tips:

  • State your drink temperature: When at Starbucks, specify 'Venti iced' to get the 24 oz size. Just saying 'Venti' could lead to a 20 oz hot drink.
  • Ask about espresso shots: If ordering a milky espresso drink, confirm how many espresso shots are included. You might need to ask for an extra shot to maintain a strong coffee flavor in a 24 oz cup.
  • Know your caffeine: Be aware that a 24 oz cold brew often has significantly more caffeine than an iced latte of the same size.
  • Bring your reusable cup: Many cafes offer discounts for bringing your own tumbler, which is a great way to save money and reduce waste.

Conclusion

Understanding what size coffee is 24 oz means navigating a landscape of unique and sometimes confusing brand-specific terminology. Whether it's the cold Venti at Starbucks, an extra-large option at another chain, or your trusty insulated tumbler, the 24 oz size is a robust and popular choice for a strong and satisfying coffee experience. By being aware of these distinctions, you can make an informed choice and get the best value for your beverage.
