Frequently asked questions

HOW DO YOUR HIGH CAFFEINE TEAS REDUCE THE JITTERS AND CRASH?

Our high caffeine teas are packed with amino acids, including L-Theanine, which studies show helps moderate caffeine’s effects.

HOW MUCH CAFFEINE IS IN ZEST HIGH CAFFEINE TEAS?

Our high caffeine teas range between 135 and 150mg of natural caffeine per serving, depending on the flavor.

IS IT REALLY THE MOST CAFFEINATED TEA ON THE MARKET?

As far as we know, yes. And by quite a margin. Zest high caffeine teas have about 3x the caffeine of normal tea, or about as much caffeine as a regular cup of joe.

CAN THE LEVEL OF CAFFEINE IN ZEST HIGH CAFFEINE TEAS BE HARMFUL?

Up to 400mg of caffeine per day is generally considered safe. With 120-150mg per serving, Zest’s high caffeine teas are comparable to a strong cup of coffee.

HOW DO YOU INCREASE THE CAFFEINE LEVELS?

We have developed an innovative proprietary blending method that enhances the caffeine levels. The extra caffeine comes from natural tea extracts. The process and ingredients used are natural.

THE TEA IS WHITE, IS THAT MOLD?

Tea in its natural form isn’t as caffeinated as we’d like it to be, so we developed a way to add more caffeine to our blends using natural tea extracts. A common side effect during this process is the whitening of the tea.

DO ZEST TEA BAGS CONTAIN ANY PLASTICS/MICRO-PLASTICS?

Despite the look, our tea bags are made of a plant-fiber material that is compostable and does not contain plastics/micro-plastics.

ARE YOUR PRODUCTS SUGAR FREE?

Our hot teas are all sugar free. Our ready-to-drink energy iced teas have 0 sugar flavors (and other, low-sugar flavors). Our powder packs contain a little sugar.

ARE YOUR PRODUCTS GLUTEN FREE?

All Zest products are gluten free.

HOW MANY CALORIES/CARBS ARE IN ZEST PRODUCTS? CAN I DRINK THIS ON A KETO DIET?

Our hot teas have 0 calories and carbs.

HOW MUCH WATER TO USE PER TEA BAG?

One serving is typically brewed with 6-8 oz of water. Some use as much as 12-15oz of water for the same amount of tea so it’s completely up to your personal preferences. We recommend starting with the standard measurements and experimenting to see what you like best.

FOR HOW LONG SHOULD I BREW THE TEA?

Use near-boiling water (freshly boiled water) and brew the tea for 3-4 min if brewing Green Tea, or 4-5 min if brewing Black Tea.
