Hammerhead: A coffee drink only served in the USA. It is an American term for a shot of espresso in a coffee cup that is topped up with drip-filtered coffee. As Kris Rosvold explains in the comments: In Oregon, the hammerhead is usually known as a red eye and uses 2 shots of espresso topped up in a 16oz travel mug with drip coffee. It's also sometimes called a "shot in the dark".
Coffee is brewed by placing the ground coffee in the empty beaker and adding hot (93-96 degrees Celsius, 200-205 degrees Fahrenheit) water, in proportions of about 28 grams (1 ounce) of coffee to 450 ml (15 fluid ounces) of water, more or less to taste. After approximately four minutes the plunger is pressed to separate the grounds and hold them at the bottom of the beaker, then the coffee is poured. Coffee press users have different preferences for how long to wait before pressing the plunger, with some enthusiasts preferring to wait longer than four minutes.
Please note that you will not see these same effects if your cup is half coffee, half cream and sugar. You might actually be worse off in that case. But if you drink black coffee, then studies show an average of 7% drop in risk for diabetes for every daily cup (6 oz.) of coffee. Typically a coffee mug is 12 oz. So if you drink, say, two mugs of coffee in the morning, or 24 oz., then you’ll have a 28% lower risk for developing type 2 diabetes, compared to those who don’t drink coffee.
Caffè crema (Italian: cream coffee) refers to two different coffee drinks: an old name for espresso (the 1940s and 1950s), and a long espresso drink primarily served in Germany, Switzerland and Austria and northern Italy (the 1980s onwards), along the Italian/ Swiss and Italian/ Austrian border. As a term, it generally means "espresso", while in technical discussions, referring to the long drink, it may more narrowly be referred to as Swiss caffè crema. Variant terms include "crema caffè" and the hyperforeignism "café crema" – "café" is French, while "caffè" and "crema" are Italian, thus "café crema" mixes French and Italian.
Caffeine is a natural stimulant that works in your brain by blocking the effects of adenosine, an inhibitory neurotransmitter  . This increases neuronal firing in the brain and releases other neurotransmitters like norepinephrine and dopamine which improves mood, reduces stress, increases vigilance and reaction time and general brain function  .
Café bombón was made popular in Valencia, Spain, and spread gradually to the rest of the country. It might have been re-created and modified to suit European tastebuds as in many parts of Asia such as Malaysia, Thailand and Singapore the same recipe for coffee which is called "Kopi Susu Panas" (Malaysia) or "Gafeh Rorn" [lit: hot coffee] (Thailand) has already been around for decades and is very popular in "mamak" stalls and "kopitiams" in Malaysia. A café bombón, however, uses espresso served with sweetened condensed milk in a 1:1 ratio whereas the Asian version uses ground coffee and sweetened condensed milk at the same ratio. On the Canary Islands a variety named "Café Proprio" or "Largo Condensada" is served using the same amount of condensed milk but a "café largo" or espresso lungo. For café bombón, the condensed milk is added to the espresso. For visual effect, a glass is used, and the condensed milk is added slowly to sink underneath the coffee and create two separate bands of contrasting colour – though these layers are customarily stirred together before consumption. Some establishments merely serve an espresso with a sachet of condensed milk for patrons to make themselves.
A Café Rápido y Sucio or a Quick & Dirty Coffee, is simply three shots of espresso topped with chocolate or mocha syrup. Unlike a café mocha which has milk added or an Americano which has water added, a Café Rápido y Sucio or a Quick & Dirty Coffee is espresso and chocolate only. Any variation of this drink containing more than three shots of espresso would be referred to as a Fast & Filthy Coffee.
I’m a bit of a coffee aficionado myself. I used to drink my coffee black but then got pregnant with The Stinky, and I couldn’t handle it black anymore. I’m also a fellow Paleo and I LOVE coconut milk (from the can) in my coffee, with a sprinkle of cinnamon and a drop of vanilla extract. It tastes like my beloved Vanilla lattes and you eventually trick yourself into thinking you’re drinking sugar. I call it a “Summer Latte”. You should try it sometime.
My mom's been a long-time lover of coffee. I can still remember her sending me up to the counter for her usual when I was a kid. “Double-tall nonfat extra hot latte with extra foam, no whip.” We lived in the coffee-loving city of Seattle before coffee was uber chic, and I like to think I inherited some of my mom's refined cafe preferences. But the fact remains that at 20-something years old, I still hadn't figured out how to make black coffee that didn't taste like mud to me. So I snooped around her kitchen when we were up to visit last weekend to see how she does it. “What's this coffee brand on your counter, mom? Gevalia?”
The method of preparing these three black coffees, namely Black eye, Red eye and Dead eye, are similar except the proportion of espresso added in each. These 3 black coffees are prepared by adding shots of espresso with dripped coffee and do not contain sugar or milk. In “Black Eye Coffee” two shots of espresso are added with dripped coffee; in Red eye, a single shot of espresso is added with dripped coffee and in Dead eye coffee, three shots of espresso are added with dripped coffee.
Too much work pressure and tension can lead to depression and stress which in turn can cause many serious health issues. But having a black cup of coffee when you feel tensed or low can boost your mood instantly and make things better. Coffee stimulates the central nervous system and increases the production of dopamine, serotonin, and noradrenaline, important neurotransmitters that elevate the mood.
