Top 5 Strongest Espresso Beans By Flavor Profiles

The following are what I consider to be the strongest espresso beans based on their flavor profiles and the strength of flavor. Let’s get on with this one.

#1 The Dharma Espresso Blend By Temple

Roast Level: Medium

Whole Bean Or Pre-Ground: Either, it’s up to you what you order.

Flavor Profile: Expect notes of caramel, cocoa and sweet berries.

Origin(s): Ethiopia, Brazil and Costa Rica.

The Dharma Espresso Blend By Temple coffee roasters is a well thought out blend of very tasty beans from South America and Africa. Available from Trade coffee, these have the expected flavors of chocolate, caramel, nuts and, to keep your taste buds on their toes, there are some hints of sweet berries.

What is very interesting is that each of the three beans are processed differently. The Brazilian beans are washed and bring around a darker, heavier body and chocolate sweetness. The Costa Rican beans are honey-processed and are naturally sweet and nutty with notes of hazelnuts and almonds.

The Ethiopian beans are fruity and naturally processed. The result is a pretty amazing espresso blend that works well with lattes, cortados and a straight shot of espresso or a macchiato with a splash of milk.

I am very confident these will be the best espresso coffee beans that you have ever tried!

Origin(s): Africa, Indonesia and Latin America.

Sumptown coffee is one of the leading coffee companies in the third wave of coffee. They have a strong focus on processing methods, cultivation and origin.

They pay so much close attention to their coffee and have a focus on sustainability.

Hair bender is a name that is an acknowledgement to the beauty parlor that occupied their first roastery before they took it over. This coffee has a rich texture and the brightness that you would expect from an Indonesian volcanic coffee. Fruity and earthy characteristics of the African and Latin American beans. I also noted some elements of dark chocolate and citrus hints.

This is a great blend and makes a good, strong tasting full-bodied espresso.
