Costa Coffee Signature Blend review summary.

Score: 3/5.

Tasting notes:

Smooth and nutty with notes of caramel.


Costa have managed to successfully produce coffee beans that will allow you to make a really solid coffee at home.

Whilst not quite shining in the black coffee department or tasting quite as good as the coffee bought in the store, coffee lovers with milk will feel right at home.

The full Costa Coffee review.

I used a French press and whole coffee beans for this review. At a bare minimum you will need a coffee maker that utilises coffee beans.

If you don’t own a coffee grinder then fear not. Costa also provide a ground coffee version, which I’ve linked to below.

The coffee itself is labelled as a ‘Mocha.’ Typically these types of coffee blends are made to be paired with milk. Black coffee drinkers should fear not! I’ve also taken the time to drink this coffee without milk so you too can decide if it is right for you.

How does it taste without milk?

If you open the packaging and take in a deep breath you will inhale a lovely, chocolatey smell. It has an earthy aroma with a hint of harshness when brewing and sipping the coffee.

The nutty flavour of the drink is much more prominent when drunk without milk. The Signature Blend is a mixture of arabica and robusta beans, with the harshness of the latter more apparent without the sweet flavour of milk to counteract this.

This by no means makes this a coffee that is overly bitter or difficult to drink. Despite its slightly heavy feel and lingering flavour, it also tasted reasonably smooth as the description on the packaging suggested.

If you are looking for a vibrant coffee bursting with lots of complex but subtle coffee flavours, you won’t get it here. The roast flavour of the coffee is more apparent and the acidity (which can bring out some of the more fruity flavours) is missing.

What you are left with is a uniform flavour that is not too harsh but not too smooth. A little bit heavy but not overpowering either. Not world beating but a good choice for people looking for an affordable coffee that strikes a balance between extremes.

How the Signature Blend tastes with milk.

Whilst drinking it straight felt quite heavy and left me wanting to grab a glass of water, adding milk naturally changed this quite a bit.

The milk masks the nutty tasting notes quite a bit but instead I detected the subtle but sweet flavour of caramel. The drink is a lot lighter and refreshing too.

People looking for a coffee that adds a bit more ‘kick’ may want to choose a heavier roast although the flavour is more enjoyable the more you drink it.

I used 40g of beans with 500ml of water to make this coffee. If you want a stronger flavour then consider using a higher ratio of coffee bean to water. This is a medium strength coffee however. Consider whether you want powerful, bittersweet flavour or something that balances flavour with smoothness.

The coffee beans really shine best when used with milk and would make a really good choice as a regular coffee to buy. They don’t quite have the same flavour as the coffee bought in store however.

Consider buying this coffee if:

  • You want a coffee that is smooth to drink.
  • A black coffee with a consistent, nutty flavour is your thing.
  • Carmel tasting notes with milky coffees sound appealing to you.

Look elsewhere if:

  • You want a fruity coffee with complex tasting notes. Pick a lighter roast coffee instead.
  • A more powerful coffee flavour is something you are after. In that case, you may want to look for a darker roast instead.

Which coffee beans does Costa use?

Costa use a mixture of robusta and arabica beans for its Signature Blend. Robusta is typically a harsher coffee whereas arabica is usually smoother to drink. When mixed in the right ratio, the combination of of these two extremes can produce a coffee that is balanced and will appeal to many people.

How fresh are Costa Coffee beans?

It really depends on where you buy them from. The fresher the better in terms of flavour. I personally wouldn’t want coffee beans more than a month old unless you usually drink your coffee with lots of milk or as a cold brew (which can mitigate against bitter flavours).

Is the Signature Blend worth buying?

At the end it really comes down to how particular you are about your coffee. Most people looking at this coffee will already be Costa Coffee drinkers in all likelihood. And in that respect, it does a fairly good job at replicating that flavour.
