Most of the caffeine produced in the USA prior to 1945 was obtained by methylation of theobromine extracted from cocoa the methylation agents used were dichloromethane and dimethyl sulfate. Synthetic production of caffeine involves the methylation of various xanthines (primarily theobromine) ( Halsey & Johnston, 1987) and theophylline ( Stanovnik et al., 1982 Nesterov et al., 1985) or the reaction of theophylline with carbon monoxide and methanol ( Bott, 1982) total synthesis can be achieved with dimethyl carbamide and malonic acid ( Anon., 1987b). The extraction yields in the production of natural caffeine have declined significantly in recent years, following the increasing use of water-based as opposed to direct solvent-based extraction procedures. Pressurized carbon dioxide is employed to remove caffeine from tea in the production of decaffeinated tea ( Anon., 1986). Refining processes are needed to provide the pure caffeine of commerce. Caffeine has been obtained as a by-product from the manufacture of caffeine-free coffee ( Budavari, 1989), initially by water and then by solvents, e.g., trichloroethylene (see IARC, 1979a, 1987), dichloromethane (see IARC, 1979b Anon., 1986 IARC, 1987), ethyl acetate ( Anon., 1986, 1987a), water-carbon dioxide processes ( Anon., 1987a), and also using oil from spent coffee grounds to remove caffeine from green coffee beans ( Anon., 1986). Extraction procedures involve three methods: direct decaffeination of green coffee beans with solvents, extraction from tea dusts and wastes and fragments of tea leaves, and extraction from cola nuts ( McCutheon, 1969 Menthe, 1985 Halsey & Johnston, 1987). One of the best parts of being a barista at Atomic is seeing what other customers order.Caffeine is produced commercially by both extraction and synthetic procedures. Mojito is a minty flavor that is perfect for the summer time. If you’re looking for a refreshing drink but aren’t a fan of a lot of flavoring, try peach mojito! Although you can add any flavor to the mojito drink, peach is the most popular. People also commonly order this drink mixed with cotton candy. Refreshing for the summer time, the popular pina colada drink is made as an energy drink at Atomic. The original cotton candy drink tastes identical to cotton candy you would purchase from the fair. This drink is one of my favorites to make when asked for a random. The greenish-teal colored drink is often ordered with pineapple flavoring.Ī fun twist on the original cotton candy drink is to add lime. This is a popular drink ordered, but some may not know about it because it’s not on the original energy drink menu. If you are looking for a flavorful drink that tastes like berries, ordering All Reds is perfect for you. While this is not commonly ordered, it is super simple and fun to make. If you are unsure of what to order, ask your barista what their favorite drink is or ask for a random energy drink If you’re looking for a drink that is a cool color, order aquamarine with cherry for a grey colored drink. This is my personal favorite! If you like sour and refreshing drinks, order this the next time you visit Atomic. In this popular energy drink, customers often order the orange drink with raspberry or peach Further, people order gummy bear with blue raspberry flavoring more often than they do just gummy bear. This drink has recently become a customer favorite!. It is also one of the coolest looking drinks to order due to the caramel drizzle on the cup and the lid!

It tastes exactly like a candy apple and is even better blended. This is the perfect fall drink if you do not like coffee. Here is a list of the top 10 energy drinks to try based on recommendations from an Atomic barista.

It is no secret that Atomic Coffee Bar is one of the most popular coffee shops among teens in the Quad Cities.
