Singles or Blends?
Not so long ago I had a minor squabble with Neil Perry via twitter on the pros and cons of single origins vs. blends in espresso beverages. Even as one of Australia’s most recognised and successful celebrity chefs, his mis-interpretation of the merits of each had me perplexed. As I attempted to explain how each performed generally as espressos the conversation got split into tangents and inevitably came to a halt, but it left me wondering how many people are confused by what ‘single origin’ or ‘blend’ actually means and how they can best be used.
The term ‘single origin’ can be a little confusing. Essentially it means coffee from one single place – either one country, one region or one single estate. It is not mixed or blended with any other coffee, be it from another or the same, country, region or farm. It is alone, one bean from one place.
A blend is anything other than that. A blend can be coffees from various countries, from various regions, or even two varying roasts of the same coffee mixed together (usually referred to as a ‘single origin blend’– just to things!).
So, why do we offer both? It’s hard to establish how blending coffees together began, but it is easy to explain why it became popular. By putting together coffees of various taste and depth, a roaster can develop flavours and textures that might not be possible in a single origin bean. When done well, a blend can bring out the best in coffees as individuals, while complementing each other to create balance, the desired taste or other aspect most sought after. Blending can sometimes hide faults in coffees and add volume as fillers, or perform better (than single origins) when mixed with milk. Traditionally, over decades, coupled with the limited technology for quality control from the growing and production of green coffee and roasting, blends produced a better outcome for espresso coffees.
Single origins coffees, whilst always having existed, have had somewhat of a renaissance in the last decade or so. This is primarily because of the rapid increase in the quality and traceability of coffees, as well as a renewed interest in single cup brewing. Even when I started in the coffee industry 17 years ago we sold the generic Colombia, Brazil or Mexican coffee. Now, we can trace our coffees back to the region, farm or estate and get a much higher quality cup.
Singe Origin coffees are however individual in their taste and not for everyone. In fact, the point of them, more often than not, is to highlight the individuality and nuances of a region, variety or processing method; aspects of flavour that can get lost if mixed with other coffees. As an espresso, single origins are most often softer in milk than a blend or sometimes a little confronting with unusual or unique characteristics as a black coffee. They are not for everyone and are almost always limited when it comes to repeating a flavour profile.
Both blends and single origins are valuable elements, especially for specialty coffee, as an avenue of sharing just how good quality coffee can taste. Blends are a fantastic way of introducing people to better coffees but ironically, as people explore coffee more and more they are inevitably drawn to tasting the distinct and diverse range of single origin coffees now available to the market. Regardless of what you prefer, if it’s a good coffee bean to start with you will almost always enjoy the experience.
