The History and Science of Coffee

Coffee has been drunk for a very long time and is now popular around the world.

Against that backdrop, the IARC (International Agency for Research on Cancer) gathered and reviewed the relevant medical research from 1991-1997 and placed coffee in Class B — largely because caffeine's effect on the nervous system is far milder than that of Class A substances such as amphetamines or heroin. For a healthy adult, caffeine's half-life is roughly 3-4 hours, and coffee's nutritional and medicinal value is considerable. The EU accordingly recommends that healthy adults cap their daily caffeine intake at 300 milligrams (mg).

Coffee Safety Concerns

The biggest safety worries with coffee are aflatoxin and ochratoxin contamination — especially in warm, humid island climates. Both toxins are produced by mold and can develop at either the green-bean or roasted-bean stage. Ochratoxin is only destroyed at temperatures between 210-270°C — and coffee roasting runs at 210-270°C for 15-20 minutes, so ochratoxin residue in roasted beans is generally far lower than aflatoxin residue (and ochratoxin's damage to the liver is far greater than the latter's).

Storage and Preservation

Under standard packaging, storage, and transport protocols, green bean contamination is rarely a problem, and green coffee keeps for up to a year. Reputable importers who monitor their storage environments pass inspection easily. The IARC is more concerned with roasted beans and their nutritional content. Roasted coffee is dry and constantly absorbs moisture, odors, and oxygen. In dry regions, whole beans kept at room temperature — without protection from oxygen and moisture — stay fresh for roughly four to six weeks; once ground, only about two weeks. The IARC therefore recommends sealing coffee beans or grounds in micro-vacuum, one-way-valve bags within 2-3 hours of air exposure, and ideally storing them in airtight glass or ceramic containers.

Artificial shelf-life extenders (nitrogen flushing, refrigeration) do little to preserve nutritional value. Nature protects the nutrients of living things far longer, but roasted coffee's natural compounds are easily destroyed and depleted by oxidation and moisture. The best strategy, the IARC concludes, is simply to use the beans quickly. That is exactly why FrontStreet Coffee advocates a healthy way of drinking coffee: small packages of beans, finished within two weeks of roasting. The peak drinking window opens about three days after roast — the day most test reports use for their samples.

Recommended Fresh-Roasted Coffee Bean Brands

FrontStreet Coffee roasts fresh single-origin beans — Yirgacheffe, Kenya AA, Panama Geisha, and more — with solid guarantees of brand and quality, suitable for all kinds of equipment. Best of all, they're excellent value: a half-pound (227g) bag costs only about 80-90 yuan. At 15g per pour-over cup, one bag brews 15 cups, so each cup of single-origin coffee works out to roughly 6 yuan — exceptional value next to café prices that often run to several dozen yuan a cup.

FrontStreet Coffee Recommendation

Once you've got freshly roasted beans, a splash of milk is one of the best ways to enjoy them. Milk softens coffee's bitterness and rounds out the texture — but different beans meet milk differently, so match the bean to the brew method. Espresso machines and moka pots both chase a concentrated base: add water and it's an americano, add milk and it's a latte, so the same beans suit both. Most Italian-style blends are roasted medium-dark so the latte shows rich nut and chocolate notes and plenty of coffee flavor.

For milk drinks, FrontStreet Coffee's Premium Blend and Black Cocoa Blend are ideal partners — Brazil-led recipes that pour almond, walnut, and other layered nut flavors into the cup, silky and lingering. If you want extra crema, choose the Classic Blend or Commercial Blend, which add a little Robusta for more golden foam plus a fuller body and caramel aroma. FrontStreet Coffee's Premium Blend pairs Brazil Cerrado with Colombia Huilan — the classic espresso taste many cafés, including FrontStreet's own shops, have poured for nearly a decade.

If you prefer pour-over with milk, go for a medium-dark single origin so its flavor isn't buried — look for flavor notes like chocolate, nuts, cream, or cocoa. FrontStreet Coffee's Brazil Queen Manor, Indonesian Mandheling, Bird of Paradise, and Colombia Huilan all fit the bill. And for iced drinks, cold brew with milk works beautifully with fruit-forward medium roasts: passion-fruit FrontStreet Colombia Sidra, the rose-tinged Strawberry Candy Geisha blend, or raisin-sweet Mozart — all balanced and easy to make at home.
