We considered the top reasons people switch from coffee to tea in making our selections, and one of those is that regular old joe can be quite tough on sensitive stomachs, with its high acidity content. However, if you're looking for the most convenient way to make a mug of tea in the morning, it might make more sense to get a box of bagged tea. Many tea drinkers prefer loose leaf because it makes it easy to customize your dose, and even mix different teas together. Some selections come in bags, while others are loose leaf.

On the other hand, Bigelow American Breakfast is a basic black that's better suited to people who want their beverage plain and simple. Tiesta Passion Berry Jolt is a sweet and fruity tea that's a good choice for those looking for strong flavors. We added two pu-erhs: Numi Emperor's Pu-erh, which comes in bags, and Solstice Tuo Cha, which comes in single-serve tea cakes.

Instead of being mixed with extracts, this type of tea is naturally more energizing as a result of its fermentation process, which also gives it a rich, earthy flavor. One green tea that does deserve a spot in this category is Celestial Seasonings Energy, which features tea extract in addition to the leafs and boasts 95mg of caffeine per serving.įor many tea lovers, pu-erh is the quintessential high-caffeine tea. For this reason, we removed Solstice Tea Traders Gunpowder, Shaklee 180, and IntegriTea Energize, as they are all green teas that have less caffeine per serving than black tea. When updating this list, we focused on making sure that every offering can truly be considered higher-than-average in caffeine, compared to a typical cup of tea.
