Let’s talk about coffee, coffee types and flavors. Flat White : The two most Kiwi coffees available are the long black and the flat white – as both originated in New Zealand and Australia. For a flat white, the steamed milk from the bottom of the jug (which is usually not so frothy, but rather creamy) is poured over a shot of espresso. It is now popular among mums and dads at school fetes who are desperately trying to stay awake. Long Black : Hot water is poured into a cup, and then two shots of espresso are poured into the water. If you do the inverse of this, it will result in an Americano. Long blacks can be quite strong, and have more crema (a creamy foam that tops espresso shots) than an Americano.
Robusta beans, on the other hand, are a much stronger and bitter bean that is produced and used in many types of espressos and even for those that prefer a really strong coffee. They tend to have around double the caffeine content of Arabica beans.
Next, the other very common type of coffee bean is Robusta. Rather than gaining its popularity through quality and depth of the brew, these plants are popular for for their high caffeine level and hardiness. While they do thrive in hotter climates and varied rainfall, Robusta beans are known for being able to put up with a much wider range of climates and altitudes. Also, they withstand diseases much better than other varieties. That resistance makes them better for growing in large crops. Higher quality robust tends to have a lower acidity and heavy body. These brews stand up better against things like cream and sugar, making them great for something like Vietnamese Coffee. And it works well in blends like Death Wish that are specifically curated for their caffeine kick.
Lungo – Lungo is often confused with Americano, but it’s not at all the same. Lungo is a long shot prepared by extracting double the amount of water with same amount of coffee grounds. In figures, it means, 50 ml of water is extracted with 7 grams of coffee. This results in extraction of more caffeine, but with dissolved off-notes of coffee. It’s a less popular drink but it’s a preferred drink for people who demand more caffeine. Caffe Crema – An extra long espresso drink served in Northern Italy, Germany, Switzerland and Austria. It has different flavor profile than related drinks like Lungo and Americano due to different extraction process. Rough brewing ratios of ristretto, normale, lungo, and caffè crema are 1:2:3:6 and the average water part per shot is 6 oz (180ml). Cafe Zorro – This is a double shot of espresso that is added to water in a 1:1 ratio. Read more details at The Best Coffee.
