Costa Spanish Latte: Taste, Calories & How to Order It

The Costa Spanish Latte has quietly become one of the most talked-about drinks on the UK coffee scene for people who want something richer and more indulgent than a standard latte. Built around espresso and a condensed milk flavoured sauce, it delivers a smooth, dessert-like coffee experience that works equally well hot or iced. This expanded guide covers the flavour profile in detail, accurate nutrition figures, ordering options, customisation possibilities, comparisons with other popular drinks, and practical tips so you know exactly what to expect before you buy.

What Exactly Is a Spanish Latte?

A Spanish Latte is essentially a classic latte elevated with condensed milk flavoured sauce. The result is noticeably creamier and sweeter than a regular Costa Latte or Flat White, with a smooth, almost caramel-like depth coming from the condensed milk notes. The drink draws clear inspiration from traditional Spanish condensed-milk coffee styles, particularly the café bombón, where a layer of sweetened condensed milk sits beneath espresso. Costa’s version integrates the sauce throughout the drink rather than leaving it layered, creating a fully blended, velvety texture.

Baristas finish the drink with a light dusting of cappuccino powder in the familiar wave pattern that Costa customers recognise. The Spanish Latte is vegetarian and contains milk. One important practical point: it cannot be made fully dairy-free, even if you switch to a plant-based milk alternative, because the condensed milk flavoured sauce itself contains milk ingredients. This limitation is worth knowing if you have a dairy allergy or intolerance.

Taste Profile: What Does the Spanish Latte Actually Taste Like?

The flavour sits somewhere between a regular latte and a mild hot chocolate. You get a clear espresso base that is softened and rounded by the condensed milk sauce, producing a rich, silky mouthfeel without the sharp sweetness that multiple flavoured syrups can bring. The condensed milk notes add a gentle caramel and creamy depth rather than a sticky or artificial aftertaste. Many people who normally find regular lattes a little plain or too bitter find this version far more satisfying.

Hot Spanish Latte tends to highlight the creaminess and espresso balance best. The warmth allows the condensed milk sauce to coat the palate more fully, making each sip feel luxurious. The iced version keeps the same flavour profile but can taste slightly sweeter overall because the cold temperature reduces the perception of coffee bitterness. Some drinkers prefer the iced version on warmer days or when they want a longer, more refreshing drink. Either way, the Spanish Latte stands out for delivering sweetness that feels integrated rather than added on top.

Costa Spanish Latte Calories and Full Nutrition Breakdown

Accurate nutrition data is essential for anyone tracking intake. For the standard medium size (semi-skimmed milk, approximately 380 ml) the figures are:

– Energy: 262 kcal 

– Fat: 6.1 g (of which saturates 3.9 g) 

– Carbohydrate: 41 g (of which sugars 33 g) 

– Protein: 13 g 

– Salt: 0.42 g 

Per 100 ml these values sit at roughly 69 kcal, 1.6 g fat, 11 g carbohydrate and 8.7 g sugars. 

Smaller sizes land lower – typically in the 190-215 kcal range depending on milk choice and exact portion size (usually around 290 ml). Whole milk increases the calorie and fat content, while skimmed milk or certain plant-based options reduce them modestly. Even with lower-fat milk, the condensed milk sauce still contributes a significant amount of sugar, so the drink is best treated as an occasional treat if you are closely monitoring free sugars. Caffeine content follows a standard double espresso base (generally 100-150 mg depending on whether extra shots are added).

These numbers place the medium Spanish Latte higher in calories and sugar than a regular medium Costa Latte (around 146 kcal) but still lower than many of the richer seasonal or chocolate-based drinks on the menu.

Sizes, Prices and Customisation Options

Typical UK pricing for the Spanish Latte falls in the £4.30-£4.80 range depending on size and location. Small is usually the more affordable option, with Medium commanding a higher price. Exact figures can vary slightly by store, city centre versus retail park, and whether you order via the app or in person.

Available sizes are normally Small and Medium. Customisation options include:

– Milk choice: semi-skimmed (most common default), whole, skimmed, soya, oat or coconut 

– Coffee type: signature blend or decaf 

– Extra espresso shots 

– Temperature: hot or iced (Spanish Iced Latte)

Because the condensed milk flavoured sauce contains milk, a fully dairy-free version is not possible. Additional toppings such as marshmallows may be offered in some locations but are optional and will increase both calories and cost. The drink appears regularly on seasonal menus and has returned multiple times due to customer demand, so availability is generally good when it is listed.

How to Order a Spanish Latte – Step by Step

Ordering is straightforward whether you prefer the counter, the app or delivery.

1. In-store: Simply ask for a Spanish Latte and specify hot or iced, size, and preferred milk. Most baristas know the drink well. 

2. Costa app: Search for “Spanish Latte”, select your customisations, and pre-order for collection. This is the quickest way to skip the queue. 

3. Delivery platforms: Available on major food-delivery apps where Costa partners operate. The same customisation fields usually appear.

For the best first experience, many people recommend starting with the hot medium-size using semi-skimmed milk. This showcases the creaminess and balance most clearly. If you prefer a lighter drink, request skimmed milk and consider a smaller size. Those sensitive to caffeine can ask for decaf without losing the characteristic flavour.

Spanish Latte vs Regular Costa Latte and Other Sweet Options

A standard medium Costa Latte is lighter in both calories and sweetness. The Spanish version deliberately trades some of that lightness for richness and a more dessert-like profile. Compared with caramel or vanilla syrup lattes, the condensed milk character feels more integrated and less syrupy. Against chocolate-based drinks such as a mocha or hot chocolate, the Spanish Latte keeps a stronger coffee identity while still delivering noticeable sweetness.

If you normally enjoy sweet coffee but find flavoured syrups too artificial or overpowering, the Spanish Latte often proves a better fit. It occupies a useful middle ground between everyday coffee and full dessert drinks.

Practical Tips for Enjoying or Lightening Your Order

– Choose skimmed milk or a lower-calorie plant option to reduce fat and calories slightly. 

– Skip extra shots if you are sensitive to caffeine or prefer a milder coffee taste. 

– Treat the drink as an occasional treat rather than a daily habit because of the sugar content. 

– Try both hot and iced versions – preferences frequently differ between the two. 

– Pair it with a simple pastry or shortbread; the buttery notes complement the condensed milk without competing. 

– Check current seasonal menus, as the Spanish Latte has returned in both winter and summer cycles.

Final Thoughts

The Costa Spanish Latte stands out for its straightforward yet distinctive flavour. The condensed milk flavoured sauce gives it a unique place among everyday coffee-shop drinks – creamy, sweet and satisfying without relying on multiple syrups. Whether you order it hot for comfort on a cooler day or iced for a refreshing treat, knowing the calorie figures, customisation limits and flavour profile helps you decide if it fits your preferences and your day. For many regular Costa customers it has become a reliable favourite that offers something genuinely different from the standard latte range.
