Whether tea is acidic is especially critical for people suffering from heartburn or acid reflux. The pH values of different types of tea vary significantly: black tea tends to be acidic, while green tea may be close to neutral or even alkaline. The factors affecting the acidity of brewed tea go far beyond the type of tea—the amount of leaves used, brewing temperature, steeping time, and whether tea bags are used all influence the final result. In addition, the caffeine in tea relaxes the esophageal sphincter, which may worsen reflux symptoms. If tooth pain occurs after drinking tea, it may also be related to acidity. This article systematically sorts out the relationship between tea and acidity, and includes recommendations for tart black teas, helping coffee and tea lovers enjoy flavor while also looking after their health.

When you see a barista in a coffee shop handling two glass bulbs, moving them up and down as if conducting an experiment, that is actually siphon brewing. It relies on steam pressure generated by heating to push hot water up into the upper chamber to contact the coffee grounds, and after the temperature drops, extraction is completed through vacuum reflux, resulting in a fuller, more solid mouthfeel and more concentrated aroma than pour-over. But not all beans are suitable for a siphon; choosing the wrong type can easily make the coffee bitter or sour. Starting from Front Street's bean-selection experience, this article first explains the working principle and flavor characteristics of the siphon, then, along three routes—beginner, advanced, and those who prefer rich and mellow coffee—recommends suitable beans such as Bird of Paradise, Strawberry Candy, Sidra, and PWN Golden Mandheling, helping you find coffee beans suited to siphon extraction.

Cold brew coffee has gained increasing favor among coffee enthusiasts in recent years, not only because of its comfortable drinking temperature, but also for its smooth, full-bodied taste and its more delicate expression of coffee bean aromas.

Is the sourness in coffee good or bad? Some people believe that sourness means the coffee is not fresh, while others regard it as a hallmark of high-quality coffee. In fact, green coffee beans themselves are rich in organic acids, most of which decompose or disappear after roasting, leaving only a limited variety of organic acids in the final cup. The latest research shows that there are not many acids that our taste buds can clearly identify, and much of the fruity acidity we perceive actually comes from the combined association of sourness with other flavors. The latest SCA cupping form classifies acidity into two categories—"sweet type" and "dry type"—helping us more accurately judge whether a coffee's acidity is good or bad. This article, from the professional perspective of Front Street Coffee, will provide an in-depth analysis of the sources of coffee acidity and the criteria for evaluating it. [more…]
