Coffee was an Earth beverage made from the roasted bean-like seeds of several types of coffee plants. There were also a number of comparable beverages from other planets that were also considered to be "coffee".
Basic Earth coffee was generally served hot and was a deep brown in color, though it could be modified in countless ways – served frozen or cold, with cream, sugar, or any number of flavorings. It usually contained significant quantities of the stimulant caffeine, and was used by many for these properties, especially in the morning.
The alien trader D'Marr, who was introduced to coffee in 2151, thought it to be "excellent". Upon learning this, Captain Jonathan Archer, who was bartering with D'Marr, offered to have Chef wrap him up ten kilograms of coffee in exchange for the location of a shipwreck. (ENT: "Oasis")
The next year, Sub-Commander T'Pol took coffee, in a thermos, to Captain Archer's quarters aboard Enterprise NX-01, in an effort to rouse him from the mind-altering effects of a specific kind of radiation from a trinary star system. After dousing Archer fully clothed in a shower stall, T'Pol poured some of the coffee into the thermos' cup and helped him drink it. Once he tasted the beverage, a slightly disgusted Archer formed the opinion it was "lousy coffee," though he continued to drink it nonetheless. (ENT: "Singularity")
When a group of Vulcan physicians came to Enterprise during an Interspecies Medical Exchange conference later that year, Captain Archer commented to Sub-Commander T'Pol, "You can bet they're not coming up for coffee and doughnuts." (ENT: "Stigma")
In January 2153, Rianna Mayweather at one point poured herself a mug of coffee in the mess hall aboard the J-class freighter ECS Horizon, while there with Travis Mayweather, and proceeded to drink it. (ENT: "Horizon")
In the Arctic Circle later that year, coffee was in a thermos that was delivered by a researcher to Doctor Moninger, who commented it was "just what the doctor ordered." Once the researcher left, Moninger began to pour some himself a cup of coffee. However, he accidentally spilled it on the ground. (ENT: "Regeneration")
Jonathan Archer was drinking coffee from a mug at the desk in his ready room when his pet beagle Porthos became agitated. Moments later, a spatial anomaly thrust the mug into the air. The coffee spilled out of the mug but became suspended in air, seemingly frozen in time. Although Archer later put the mug back on his desk, he left the coffee suspended.
Later in 2153, when Jonathan Archer entered a saloon in North Star, a bartender offered him some coffee "on the house", which Archer accepted and drank. He subsequently requested more coffee. This request diffused a high-tension incident involving Deputy Bennings and two cowboy companions bullying a Skagaran named Draysik, who helped out in the saloon and from whom Archer requested the coffee. After Sheriff MacReady entered the establishment and inquired into Archer's intentions, MacReady persuaded Archer that the climate was too hot for coffee, so Archer exited the saloon. (ENT: "North Star")
In an illusion created by the Talosians in 2254, Vina asked Christopher Pike if he wanted coffee while she was preparing for them to have a picnic in what was apparently parkland near Pike's hometown of Mojave. Vina told Pike the coffee was in a thermos that was hooked to a saddle. Though Pike fetched the thermos, he and Vina actually drank none of the coffee before their illusory surroundings changed. (TOS: "The Cage", "The Menagerie, Part II")
Some junior officers aboard the USS Enterprise had a low opinion of the ship's coffee in 2267. When Charlene Masters offered coffee to her colleague, he joked, "Is that an order, lieutenant?" Yeoman Rand's brew, which she phaser-heated after the galley lost power, was more welcome on the bridge in a time of crisis. (TOS: "The Alternative Factor", "The Corbomite Maneuver") When Hikaru Sulu and his landing party were stranded on the freezing surface of planet Alfa 177, he asked that the Enterprise lower down a pot of hot coffee on a long rope. (TOS: "The Enemy Within")
Captain James T. Kirk sometimes enjoyed coffee, but in 2268, he was dismayed when tribbles that had infested the Enterprise got into his chicken sandwich and coffee that he had ordered from a food synthesizer. (TOS: "The Trouble with Tribbles"; DS9: "Trials and Tribble-ations")
Some believed coffee was capable of curing drunkenness or a hangover, as Dr. Leonard McCoy indicated in 2293; following an unsettling dinner with Klingon chancellor Gorkon on the USS Enterprise-A in that year, McCoy planned to find himself a pot of black coffee. (Star Trek VI: The Undiscovered Country)
While Jean-Luc Picard was most known for being fond of Earl Grey tea, his preferred breakfast menu, often shared with Beverly Crusher, was coffee and a croissant. (TNG: "The Perfect Mate") He also enjoyed a French-press coffee and sandwich on route for a medical procedure at Starbase 515. (TNG: "Samaritan Snare")
In 2369, after Commander Benjamin Sisko ordered coffee from a replicator on ops, he yelled at Chief Miles O'Brien, having thought the chief had repaired the replicator. Later, O'Brien ordered a "Hot coffee, black, double sweet," and was surprised about the good coffee. (DS9: "Babel")
Miles O'Brien preferred a Jamaican coffee blend, double strong, double sweet. (DS9: "Whispers") Keiko O'Brien believed he never drank coffee in the afternoon; this formed the basis for Miles' and Julian Bashir's rescue from T'Lani III, only after which did Miles tell his wife that he drank coffee in the afternoon all the time. (DS9: "Armageddon Game") Kira Nerys also sometimes enjoyed coffee. She held a personal philosophy that coffee should be a little too hot to drink right away, as it slowed down the experience and gave you time to savor the taste. (DS9: "Meridian")
In 2372, Constable Odo had a conversation with Garak in the Replimat, explaining how he could simulate sharing the dining experience with others (despite not needing food) by "creating" food with his own body and reabsorbing it through a mimicking of eating or drinking, reproducing more if need be. In demonstration, he morphed part of his body into a cup of coffee. (DS9: "The Way of the Warrior")
In 2373, when Rom ordered eggs over easy, bacon and corned beef hash for breakfast, Quark sarcastically suggested that orange juice and coffee would be next, and Rom thought this was a nice idea. (DS9: "The Assignment")
Captain Kathryn Janeway was well known for her addiction to black coffee (with no milk or sugar). She consistently had a cup first thing in the morning, sometimes in lieu of breakfast (VOY: "The Cloud", "Bride of Chaotica!"), and often refused to start the day without it. One stressful day in 2374, she had her fourth cup before the morning was over, and doubted it would be her last. (VOY: "Hunters") Very rarely, sometimes she also enjoyed coffee with cream. (VOY: "Caretaker") She once attempted to give it up, without success. (VOY: "The Cloud") She also occasionally enjoyed what appeared to be espresso. (VOY: "Prime Factors") By 2377, Neelix was intimately familiar with her standing order, "Coffee, black," as she had not changed it in seven years. (VOY: "Shattered") In an alternate future, Admiral Janeway gave up coffee after she returned to the Alpha Quadrant, though she quickly had a relapse after traveling back in time to Voyager in 2378. (VOY: "Endgame")

In the final draft script of TOS: "The Man Trap", Uhura was referred to as "toying with a cup of coffee" during a private discussion between herself and Spock, on the USS Enterprise's bridge. No such cup of coffee appears in the final version of that scene, however.
In ultimately omitted dialogue from the final draft script of TOS: "The Naked Time", Kirk told Yeoman Janice Rand, during a briefing, that he and his fellow senior officers "could use some coffee," so Rand left the group with the intention of complying with the request. In the final version of the scene, not only is there no such reference to coffee but Rand seems to disappear midway through the scene, her sudden absence left unexplained.
In the final draft script of TOS: "Court Martial", Stone poured himself a cup of coffee and offered Kirk some coffee, before Stone began questioning Kirk in Stone's office at Starbase 11. Kirk declined the coffee, eager to start the inquisition. This scene wasn't included in the episode's revised final draft script, nor is in the final version of the installment.
According to Star Trek: Deep Space Nine collector and archivist Penny Juday, the specific mugs used on Deep Space Nine for coffee and raktajino were fabricated by a local fabricator and the art department used specific colors on the series. The red/burgundy ones were used at Quark's, the green ones in Ops, and the light blue ones in the Replimat. ("Secrets of Quark's Bar", DS9 Season 1 DVD special features)
In omitted dialogue from the final draft script of ENT: "Two Days and Two Nights", Jonathan Archer offered Keyla some coffee one night while they were at a villa Archer was staying in, on Risa. Keyla was unfamiliar with the beverage, so Archer explained, "It's an Earth drink. I'm sure they'll have something like it here." Lightly, he added, "When people first meet, it's sometimes considered... traditional to have a cup of coffee together." As Keyla didn't want to "break a tradition," Archer decided to order some coffee. When Keyla returned to Archer's villa the next day, she specifically requested "no more coffee" because she had experienced trouble sleeping. Archer apologized and remarked, "The local blend's a lot stronger than I'm used to."
On May 3, 2015, the International Space Station activated the first true zero-gravity coffeemaker nicknamed the "ISSpresso." Italian Astronaut Samantha Cristoforetti sent out a picture of herself wearing a Deep Space Nine/Voyager command uniform without rank device while drinking the inaugural cup in the station's observation module with Janeway's quote as a caption.
