They use whole tea leaves as a base. This makes a huge difference in the way your tea tastes. Even though it is a black tea base, it is not the astringent low quality that most other brands use. Inexpensive black teas, often found in the opaque small stapled tea bags, are made essentially from shake mechanically processed remnants. These often leave what looks like grounds on the bottom of the packaging and often in your cup as well. It is often used as is it very inexpensive. They have a very drying feel to the tongue and a very strong overpowering flavor. Which can overpower your flavored teas. Most brands use variations of these. Not this company. This brand uses hand-picked Nilgiri whole leaf & Orange Pekoe Flower. Pekoe is often the base for iced tea. So it is a light refreshing amber color when steeped. So, even if you over-steep these bags, it will not taste sour or bitter. They use real oil of bergamont not flavoring of bergamont. You can see the oils crystalized on the tea leaves in their pyramid silk bags. The oils of bergamot have a much more complex and realistic flavor when steeped. So, if you are balking at the price these are the probably the reasons why they are more expensive. Not to mention the caffeine extract they use! Which I can assure you is the same as a cup of coffee. 150mg's of caffeine is in these individual bags. So, they pack quite a punch and help you face the morning! Tea leaves naturally contain L-thenaine which relaxes the mind. Drinking it energizes your body without feeling like your mind is racing. Although this tea, not unlike coffee, can leave your body feeling jittery if you have not eaten. Caffeine is highly water soluble though. So, if you want to reduce the amount of caffeine you can just pour any temperature water over the tea bag, then quickly pour it out before the tea starts to release color. But hey if you are buying this tea then you must want the high voltage caffeine to start your day :) Any tea lovers should definitely try this brand. You will be hooked on the flavor alone and the caffeine will keep you coming back for more.

The Blue Lady is the best iced tea I've ever had, with the Pomegranite Mojito coming in a close second. I add plenty of fresh-squeezed lemon and sugar. I use four bags to make roughly a half-gallon of iced tea. This ensures the flavor and caffeine potency shine through and aren't diluted. **Q: Why is there no nutritional information label on this product? I would like to know the sugar and calorie content of it, if any.** A: There is no sugar or calories in Zest Tea. Most teas are not required to put nutritional panels on the labels, because they would read 0 all the way across. **Q: What material are the sachets made of?** A: It's not the same material as a normal tea bag. Kind of a silky tulle. It still has the string and paper to hold it with though. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Quality whole leaves, real bergamot, and high caffine! *by J***Y on July 27, 2015* Zest-tea is a very high quality tea for the tea connoisseur that is only missing caffeine.

I use 2 each morning for one cup of tea. This tea does not give you the crash lots of other caffeine drinks do. The flavor is a lil earthy but tastes fine. ## Frequently Bought Together - Zest Tea Premium Energy Hot Tea, High Caffeine Blend Natural & Healthy Traditional Black Coffee Substitute, Perfect for Keto, 150 mg Caffeine per Serving, Blue Lady Black Tea, Tin of 15 Sachet Bags - Zest 150mg High Caffeine Energy Leaf Blend - Blue Lady Black Tea - 20 Pack Bag - Hot or Iced - All Natural Strong Flavored Healthy Coffee Alternative Highly Caffeinated Substitute - Perfect for Keto - Zest 135mg High Caffeine Energy Leaf Blend - Superberry Samba Green Tea - 20 Pack Bag - Hot or Iced - All Natural Strong Flavored Healthy Coffee Highly Caffeinated Substitute - Perfect for Keto Diet --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.hr/products/14816789-zest-energy-tea-bags-blue-lady-passion-fruit-black-tea](https://www.desertcart.hr/products/14816789-zest-energy-tea-bags-blue-lady-passion-fruit-black-tea) --- *Product available on Desertcart Croatia* *Store origin: HR* *Last updated: 2026-06-10*
