Costa Dragon Fruit & Guava Refresher UK Price & Calories 2026
The size choice matters more than usual with the Dragon Fruit & Guava Refresher. The Small is £4.50 and the Medium is £4.75, so you’re paying 25p more for an extra 100 ml. On a weekend walk, I stopped at a Costa beside a busy bus stop because I wanted a cold takeaway drink, and this is exactly the sort of order where I’d check the price gap before choosing.
My short answer: the Medium makes the most sense if you actually want a proper cold drink to carry with you. The calorie jump is there, but it’s not huge: 95 kcal in Small and 131 kcal in Medium. The bigger thing to notice is sugar, because the Medium has 19 g.

Price, portion and value
For a cold refreshing drink, the Dragon Fruit & Guava Refresher sits in a simple two-size choice: Small at £4.50 or Medium at £4.75. There’s no Large in the provided size list, so the decision is really whether the extra 25p is worth it.
On value, the Medium is the stronger pick. You get 391 ml rather than 291 ml, which is a 100 ml increase for 25p. That’s a meaningful difference if you’re taking it away, drinking it slowly, or want something to last beyond a quick stop.
The Small still has a role. If you only want a short cold drink, or you’re mainly keeping an eye on sugar, it saves 36 kcal and 5 g sugar compared with the Medium. But if price is the deciding factor, the Small doesn’t save much money.
Best size for most people
I’d choose the Medium. The price gap is small, the portion jump is clear, and 131 kcal is still fairly modest for a sweet cold drink. It’s the size that makes most sense if you’re buying it as a proper refresher rather than just a few sips.
Choose the Small if you’re trying to keep the order lighter. It’s 95 kcal, has 14 g sugar, and is still 291 ml, so it isn’t tiny. But because it’s only 25p cheaper, I’d only go Small if the lower sugar or lower calories matter more to you than value.
Dragon Fruit & Guava Refresher calories and nutrition
Dragon Fruit & Guava Refresher has 95 kcal in Small and 131 kcal in Medium. The default size is Medium, so the main order to judge is 391 ml, 131 kcal and 19 g sugar.
The Medium’s 131 kcal is just below a can of Coke at around 139 kcal, which is a useful way to think about it. This doesn’t make it a plain light drink; it’s still a fruity, sugary cold option. But it’s not in the same calorie territory as heavier dessert-style drinks.
The bit people can miss is that the calories are not the only number that changes. Moving from Small to Medium also takes sugar from 14 g to 19 g, carbs from 22 g to 30 g, and salt from 0.03 g to 0.04 g. Fat stays low in both sizes at 0.3 g for Small and 0.4 g for Medium.
| Size | Portion (ml) | Energy (kcal) | Energy (kJ) | Sugar (g) | Fat (g) | Saturates (g) | Carbs (g) | Protein (g) | Salt (g) |
|---|---|---|---|---|---|---|---|---|---|
| Small | 291 | 95 | 397 | 14 | 0.3 | 0.3 | 22 | 0.5 | 0.03 |
| Medium | 391 | 131 | 549 | 19 | 0.4 | 0.4 | 30 | 0.7 | 0.04 |
Calories, sugar and the bit people miss
This is a refreshing drink, but it isn’t sugar-free. The Medium has 19 g sugar, which is the number I’d look at before ordering it often. The Small has 14 g sugar, so downsizing makes a real difference if sugar is your main concern.
Protein is very low in both sizes: 0.5 g in Small and 0.7 g in Medium. That means this is a drink for refreshment, not something that will add much substance to your order. Salt is also low at 0.03 g in Small and 0.04 g in Medium.
So the decision is fairly straightforward: go Medium for better value and a longer drink, or Small for the lower sugar and calorie count.
Would I buy it again?
Yes, but I’d buy it for the right moment. The Dragon Fruit & Guava Refresher makes sense when you want something cold, fruity and easy to take away. It’s a better fit for a warm-day drink than for anyone looking for a filling option.
For most people, I’d recommend the Medium. Paying £4.75 instead of £4.50 gets you 391 ml rather than 291 ml, and that extra 100 ml makes the order feel better value. I’d skip the Medium only if you’re trying to keep sugar closer to the Small’s 14 g rather than the Medium’s 19 g.
The main thing is to order it knowing what it is: a sweet fruity refresher with moderate calories, not a plain low-sugar drink. If that’s what you want, the Medium is the sensible choice.
