We’re always experimenting with new flavors and refining blends to create exceptional loose-leaf teas our customers love. In 2025, we introduced a wide variety of new teas - ranging from indulgent fan favorites like Pistachio White Chocolate (voted Best New Tea in the 2025 BesTeas Awards), to refreshing herbal and fruit teas like Tranquil Peach, and comforting everyday favorites such as Raspberry Ginger White, Citrus Mint Green, and Serenity. We also expanded our selection of rare and premium teas with offerings like Yunnan Gold Tip and Yunnan Pu-erh.
Seasonal releases played a big role in 2025 as well, with the debut of winter favorites Butterscotch and Spiced Pear, along with the limited-time return of a nostalgic customer favorite, Cotton Candy.
This year also marked the launch of Whistling Kettle Communi-Tea, a quarterly initiative where we create an exclusive, limited-edition tea to support a nonprofit partner, donating a portion of proceeds from each blend. Featured Communi-Tea collaborations include Sip for Cystic Fibrosis: Salty Caramel and Uni-Tea: Caramel Apple Chai.
With more than 180 loose-leaf teas in our collection, narrowing it down wasn’t easy - but these 10 blends clearly stood out as our best-selling and most popular teas of 2025. This year’s list looks different than years past, featuring exciting new additions and a new tea taking the number one spot. If you’re looking for the best teas to try, these customer favorites are the perfect place to start.
Here's our top 10 best-selling teas of 2025:
#10 - Belly Buddy
Belly Buddy is our go-to when we need something to settle our stomach, and that seems to be the case for our customers as well! Made with peppermint, ginger, burdock root, and lemon balm - this tea is formulated with all the herbs you need whenever your stomach is feeling off or just to help with digestion after dinner.
"Belly Buddy works wonders when the tummy isn't feeling so great but also has an extra benefit of being really tasty!" - Holly
#9 - Milk Oolong
If you love smooth, layered oolongs, this Milk Oolong is an elegant, comforting choice that stands out for its unique creamy character, repeatable steeps and true-to-cultivar flavor. This Jin Xuan cultivar is prized for its naturally creamy character, a silky mouthfeel and a gentle, buttery sweetness that brings to mind custard, fresh cream and baked pastries.
"Delicious milk oolong. This is my go-to milk oolong. So many have added flavoring, but this is just the tea leaves. It is smooth, creamy, and a bit sweet. Excellent tea for a good price." -Corey C.
#8 - Almond Lemon Panna Cotta
Almond Lemon Panna Cotta is a dessert-in-a-cup, built on a smooth black tea base and inspired by the classic Italian treat. If you love lemon pastry teas, almond-forward blends, or creamy dessert flavors, this is an easy reach for a comforting afternoon cup or a sweet ending to any meal.
“I had slept on this tea for almost a year, moving it into my cart on almost every visit to the site and then removing it because I juuuust wasn't sure I would like it enough. Finally took the chance and it's knocking my socks off. The flavor is exactly right, creamy mouthfeel and as good iced as it is hot. I learned my lesson- don't sleep on this tea!" -Katie G.
#7 - Organic English Breakfast
Our Organic English Breakfast is a classic full-bodied black tea, crafted from organic Assam and Ceylon leaves for a robust, malty cup with subtle caramel notes. It pours dark and brisk, with enough backbone to stand up to a splash of milk or a touch of honey, yet smooth enough to enjoy black. Many customers tell us they reach for it every day, hot or cold, and some even use it as a base for home-brewed kombucha. If you like a dependable, characterful black tea that performs well with or without milk, this one is a favorite.
"Excellent taste. Smooth and bold taste. Very pleased." - Stephanie S.
#6 - Feel Better Tea
Our Feel Better tea has a green tea base and is packed with herbs such as echinacea, elderberry, rosehips, and sage. The taste is sure to brighten up your day with fruity bits of dried mango, gojiberry, and tart raspberry. Customers say it has a "great taste" with light, fruity flavors featuring mango, raspberry, and spearmint. Many praise its effectiveness for colds, sore throats, and immunity support, noting "it really does make you feel better."
"Lives up to its name! This tea absolutely makes me feel better! It's light and fruity but not overwhelming with sweetness. Just holding a cup of this tea and breathing it in is so calming. Definitely a favorite!" - Carrie C.
#5 - Carrot Cake
Our Carrot Cake tea is a unique blend you won't find in the grocery store or at other tea shops, making it extra special. It has all the qualities of a fresh slice of carrot cake, without the carbs or calories, plus zero caffeine. Many customers love it as an evening cup or a post-dinner dessert substitute, and it keeps its full, cake-like character whether sipped hot or poured over ice.
“OMGOODNESS! I absolutely found a new favorite! This Carrot Cake is truly a dessert in a cup, or in my case a giant 21oz stainless steel flask.. I love it with just one Stevia and one creamer. It’s already pretty sweet and creamy on its own. If you like carrot cake, you won’t be disappointed with this one!” - Julie P.
#4 - Sleep Tight
Sleep Tight is a favorite for winding down at the end of the day. Formulated to promote restful sleep with additions of Chamomile and Valerian Root, Sleep Tight is a must-have for your bedtime routine. Many customers enjoy its calming aroma and easy flavor, and some find it a helpful part of their nightly routine.
"I can't say enough good things about this tea and its ability to put me into a sound sleep naturally each night. My husband even started struggling to stay asleep at night, so I offered him a cup one night to see if it would help. No surprise to me, he also slept like a baby log.. This one's a staple in our household from here on out." -Jen
#3 - Earl Grey Cream
Keeping its spot in our top 3 - Earl Grey Cream takes the classic flavor of Earl Grey and takes it up a notch with the addition of creamy flavor and sweet mallow blossoms. Think vanilla earl grey! 🍦
"The BEST Earl Grey. I've been drinking Earl Grey for 20+ years and this is by far my favorite loose leaf. Robust, creamy, fragrant! Everything you want in EG." -Lauren F.
#2 - SnowFlake
It was a close one between our top 3.. but our most popular blend of nearly 20 years has officially been dethroned! Keeping its place in our top 3, SnowFlake is a delicious combination of almonds, coconut, and cinnamon resulting in a delightful, comforting brew no matter the time of the year.
"Snowflake has been the perfect companion on these chilly summer nights. The comforting mix of almonds, coconut, and cinnamon creates a warm, sweet-spiced cup that feels indulgent yet soothing. Its fragrant aroma and smooth flavor make it a year-round favorite I keep coming back to." -Michael B.
#1 - Medicine Ball Tea
Last year, Medicine Ball made its way into our top 3 best sellers of 2025. This year, it easily took the #1 spot. We introduced Medicine Ball tea to our catalog in 2023 in limited quantities, but when we kept getting requests for more, we knew it had to stay permanently. The blend is inspired by the Starbucks Honey Citrus Mint tea, and has quickly become a fan favorite. It combines green citrus mint and peach chamomile herbal teas for the perfect drink for when you're feeling under the weather, or even when you're just in the mood for a tasty cup of tea.
“The best honey-citrus-mint blend I’ve ever tasted - beautifully balanced, unmatched in quality, and no other tea compares.” -Barbara Q.
