The Trenta Starbucks size is the largest cup on the menu, holding 31 oz (917 ml) of liquid. It is available for cold drinks only: iced coffee, cold brew, iced teas, and Refreshers and costs roughly $0.50 more than the same drink in a Venti. Most customers never know the Trenta Starbucks exists because it does not appear on the in-store menu board.
What Is the Trenta Starbucks Size?
The Trenta is the biggest cup size at Starbucks. It holds 31 oz (917 ml) of liquid. That is nearly a full quart. For context, the average adult human stomach holds roughly 30 to 32 oz at capacity. A full Trenta sits right at that limit.
Starbucks introduced the size in 2011. It started as a test in Phoenix and Tampa, then rolled out nationwide by May 2011. The name comes from the Italian word for thirty. Starbucks has used Italian naming for its sizes since founder Howard Schultz visited Italy in 1983 and wanted to bring that coffeehouse culture to America. All Starbucks sizes, i.e., Tall, Grande, Venti, and Trenta, follow that same Italian thread.
How Much Is a Trenta at Starbucks?
Prices vary by location and drink type. Starbucks prices in New York or Los Angeles run slightly higher than in smaller cities.
| Drink Type | Trenta Price Range |
| Iced black or green tea (unsweetened) | $3.45 to $4.50 |
| Iced tea lemonade | $4.50 to $5.25 |
| Iced coffee | $4.75 to $5.25 |
| Cold brew | $5.25 to $6.25 |
| Refreshers | $5.25 to $6.50 |
| Refreshers with lemonade | $5.75 to $6.75 |
The Trenta costs roughly $0.50 more than the same drink in a cold Venti. That is the standard upsize price Starbucks set when it launched the size, and it has remained consistent. If you order through the app, you can see the exact Trenta price for each drink before you confirm.

What Drinks Can You NOT Get in Trenta?
Just as important as knowing what you can order is knowing what you cannot.
Hot drinks are completely off the table. No hot lattes, cappuccinos, brewed coffee, or hot teas come in Trenta. The official reason has never been confirmed by Starbucks, but the most likely explanation is heat retention and safety. A 31 oz cup of hot liquid is genuinely hazardous to carry, and cup construction for hot drinks is different.
Frappuccinos are not available in Trenta. Blended drinks cap out at Venti.
Cold espresso drinks like Iced Lattes, Iced Macchiatos, Iced Americanos, and Shaken Espresso drinks are also not available in Trenta. This one surprises people. The reason appears to be recipe consistency. Adding more milk to meet a 31 oz volume throws off the espresso-to-milk ratio and changes the flavor profile significantly.
| Drink Category | Trenta Available? |
| Hot coffee / lattes | No |
| Frappuccinos | No |
| Iced espresso drinks (lattes, macchiatos) | No |
| Shaken espresso | No |
| Iced coffee | Yes |
| Cold brew | Yes |
| Iced teas | Yes |
| Refreshers | Yes |
Trenta Starbucks Calories and Nutrition
The calorie, caffeine, and sugar counts for every major Trenta drink are the following:
Cold Brew and Iced Coffee
| Drink (Trenta 31 oz) | Calories | Caffeine | Sugar |
| Cold Brew (black) | 5 | 360 mg | 0g |
| Iced Coffee (black, unsweetened) | 5 | 320 mg | 0g |
| Iced Coffee with classic syrup | ~120 | 320 mg | ~30g |

| Salted Caramel Cream Cold Brew | 310 | ~320 mg | 37g |
| Honey Almondmilk Cold Brew | ~200 | ~320 mg | ~30g |
Important caffeine note: A plain Trenta Cold Brew has 360 mg of caffeine. The FDA recommends a daily maximum of 400 mg for healthy adults. One drink gets you 90% of that limit. If you are sensitive to caffeine, this is worth knowing before you order.
Iced Teas
| Drink (Trenta 31 oz) | Calories | Notes |
| Iced Black Tea (unsweetened) | 0 | Zero calorie option |
| Iced Black Tea (sweetened) | 70 | |
| Iced Black Tea Lemonade (unsweetened) | 90 | Lemon adds natural sugar |
| Iced Black Tea Lemonade (sweetened) | 220 | |
| Iced Green Tea (unsweetened) | 0 | Zero calorie option |
| Iced Green Tea (sweetened) | 140 | |

Refreshers

| Mango Dragonfruit Refresher | 280 | ~90 mg | ~61g |
| Mango Dragonfruit Lemonade Refresher | 280 | ~90 mg | ~61g |

| Pink Drink | 270 | ~90 mg | ~48g |
| Dragon Drink | 280 | ~90 mg | ~50g |
Refreshers get their caffeine from green coffee extract, not espresso. The caffeine is natural, but it is still real. At the Trenta size, most Refreshers carry around 90 mg of caffeine per cup.
Lowest Calorie Trenta Options
If you are watching your intake and counting the calories, the Trenta can still work for you. These are your best picks:
| Drink | Calories | Caffeine |
| Iced Black Tea (unsweetened) | 0 | ~25 mg |
| Iced Green Tea (unsweetened) | 0 | ~25 mg |
| Cold Brew (black) | 5 | 360 mg |
| Iced Coffee (black, unsweetened) | 5 | 320 mg |
| Iced Passion Tango Tea (sweetened) | 70 | ~25 mg |
| Iced Black Tea (sweetened) | 70 | ~25 mg |
The unsweetened iced teas are a genuinely good choice for calorie-conscious customers. Zero calories, a light amount of caffeine, and still 31 oz of cold drink on a hot day. If you want caffeine without calories, the black Cold Brew is 5 calories for the full 31 oz. Just respect the 360 mg caffeine count.
Why Is the Trenta Not on the Menu Board?
Starbucks does not advertise the Trenta on its in-store boards. It does appear in the app when you select eligible drinks. This has been true since the size launched in 2011. The most likely reason is menu simplicity. Tall, Grande, and Venti cover the vast majority of orders. Listing a fourth cold-only size adds clutter and confusion.
Keeping it off the boards also keeps the focus on the standard menu without making cold-drink customers feel like they are missing out. But it is a fully real, fully available size at every US Starbucks location.
How to Order a Trenta at Starbucks
Ordering is straightforward once you know the format. Starbucks takes sizes at the start of the order. Just say: “Trenta [drink name], please.” For example:
- “Trenta iced black tea, unsweetened”
- “Trenta cold brew, no ice”
- “Trenta Strawberry Acai Refresher”
In the app, select your drink, tap the size option, and Trenta will appear for eligible cold drinks. The app also shows you the exact calorie count and price before you confirm. If a barista says Trenta is not available for a specific drink, it is because that drink falls into an excluded category, not because your location does not carry the size.
The Trenta Starbucks size is the ultimate option for customers who want the maximum drink volume in a single cup. If you’re exploring all Starbucks cup sizes and want to understand how Trenta compares with Tall, Grande, and Venti, then the Trenta Starbucks is at the top end of the size range for cold beverages.
