Regarding caffeine in tea, many plausible-sounding claims circulate: some believe black tea has far more caffeine than green tea, some think green tea contains almost no caffeine, and others are convinced that the deeper the fermentation, the more caffeine. Is any of this actually true? All tea leaves from the tea plant—unless decaffeinated—inherently contain caffeine, and the level depends more on plucking tenderness, tea cultivar, cultivation methods, and climate conditions than on the degree of fermentation or oxidation. Buds and newly opened leaves have the highest caffeine concentrations, African Assamica tea plants are generally higher than Chinese varieties, and older leaves plucked in autumn tend to be lower. In addition, theanine, unique to tea, works synergistically with caffeine to deliver a calm yet alert lift—quite different from the jolt of coffee. This article breaks down these factors one by one and explains why Front Street Coffee labels the caffeine content of the teas it sells, helping you make a more suitable choice based on your own tolerance.

Tea is both an everyday beverage and something that can affect rest at night. The fresh leaves of the tea plant naturally contain caffeine, a stimulant that can disrupt sleep rhythms, but tea's caffeine content is far lower than that of coffee, and it also contains components such as L-theanine that participate in relaxation and sleep regulation.

In addition, herbal teas contain no caffeine, and some types, such as valerian and chamomile, have been shown to help improve sleep, while potent herbs like kava and valerian need to be used under the guidance of professionals. Only by understanding the characteristics of different types of tea can you choose the right cup to calm the mind and aid sleep, and avoid insomnia caused by improper drinking. [more…]

The choice of water temperature when brewing tea directly determines the flavor performance of the tea. Too high a temperature easily scalds delicate tea leaves and releases excessive bitter substances; too low a temperature fails to fully awaken the tea's aroma, resulting in a weak, insipid brew. Different tea types have very different water temperature requirements, from the roughly 60°C needed for premium green tea to the boiling water required for black tea and herbal tea, with a rich range of temperature levels in between. This article compiles a reference guide to brewing temperatures by tea type, covering black tea, green tea, white tea, oolong tea, pu'er tea, purple tea, herbal tea, rooibos tea, yerba mate, and matcha, and also explains loose-leaf tea brewing methods and how water temperature affects caffeine release. Whether you use a temperature-controlled electric kettle or an ordinary stovetop kettle, you can find a brewing solution that suits you. [more…]

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.

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.
