Coca-Cola Co.’s reformulated Zero Sugar Gold Peak tea, rolling out this month, comes as the bottled and canned tea category faces mounting pressure to reignite growth and brands test how flavor, function and formulation can win over consumers.
“RTD tea has gained strong relevance in the global beverage industry as consumer shift from carbonated soft drinks toward lighter, refreshing, lower-sugar, antioxidant-positioned and functional non-alcoholic beverages,” helping it reach an estimated $83.33 billion in sales in 2025, according to Fortune Business Insights.
But, it adds “rising scrutiny over sugar content, sweeteners, artificial flavors and plastic packaging,” are constraining the market, and the high levels of added sugar in many traditional iced tea products “can weaken their health positioning compared to unsweetened tea, flavored water and other functional beverages.”
Likewise, “as consumers become more label-conscious, manufacturers face pressure to reformulate products without compromising taste, shelf life or affordability,” it adds.
While Fortune Business Insights is bullish on the category’s long-term outlook, projecting a compound annual growth rate of 4.81% globally through 2034, recent data from Circana suggests brands face immediate losses that must be addressed to seize the segment’s long-term potential.
In the 52 weeks ending April 19, Circana reported US bottled and canned tea sales fell 1.5% year-over-year to $4.8 billion.
Mintel echoed both these sentiments in its US Tea and RTD Tea Market Report 2026 in which it characterized the category as “mature” and “sluggish” with value sales forecast to rise 0.5% in 2026 to $10.6 billion.
Like Fortune Business Insights, however, it also sees the segment’s potential, noting “significant shifts are taking place: consumption of green, herbal, chai and matcha teas are growing.” It also notes RTD tea usage has increased to 61% of tea consumers and younger adults are embracing more tea types and formats “than ever before.”
RTD brands renovate and innovate to remain relevant
Against this backdrop, Coca-Cola and other category players are launching new and reformulated RTD teas designed to meet consumer interest in beneficial beverages and at the same time deliver uncompromised taste experiences and flavors that are familiar and novel.
For its part, Coca-Cola revamped its Zero Sugar Gold Peak tea with a “new and improved” formula that it says “delivers an authentic, more delicious tea experience.”
A comparison of the ingredient decks show the new version, like the old, begins with a base of brewed black tea leaves that are sweetened with aspartame and acesulfame potassium, also known as Ace-K or E950, both of which are roughly 200 times sweeter than table sugar, which allows for minimal use and virtually no additional calories.
But, unlike the old version, the new formula appears to skip the natural flavors, citric acid and caramel color.
Coca-Cola’s Zero Sugar bid speaks to consumer demand for low- and no-sugar options, which are becoming table stakes not only in the RTD tea space but across the beverage category. A key differentiator between competitors are the sweeteners used in place of sugar.
For example, Pure Leaf Zero Sugar, made by the Pepsi Lipton Partnership between PepsiCo and Unilever, combines brewed black tea with sucralose, citric acid, citrus pectin and acesulfame potassium. Milo’s Zero Sugar Sweet Tea blends filtered water, fresh brewed tea and sucralose; and Snapple Zero Sugar uses aspartame as the primary sweetener blended with filtered water, citric acid, tea, potassium citrate and natural flavors.
Flavors balance nostalgia and approachable novelty
Beyond different sweetener systems, some RTD players are trying to secure market share by offering unexpected limited edition flavors that drive excitement. For example, in March, Saint James Iced Tea introduced Classic Mango and in April Ryl Tea collaborated with Jolly Rancher to launch a trio of zero-sugar teas in Blue Raspberry, Green Apple and Cherry.
In March, Spindrift entered the RTD category with a line of non-carbonated ice teas that it promoted as flavor forward, thanks to “real squeezed fruit,” and “made without ultra-processed shortcuts.” The line-up included classics like Lemon Black Tea and Peach Green Tea as well as unexpected combinations of Blood Orange Black Tea and Raspberry Black Tea.
Premiumization is prized in reformulations
The emphasis many brands place on “real-brewed” or “fresh-brewed” tea underscores consumers’ shift toward premium and “clean” ingredients.
When the brand Birdie reformulated and relaunched as Orcha in July it said it “reformulated its beverages from tea extract to real brewed tea following consumer feedback.” It explained that the swap helped “create a more pronounced tea flavor.” In line with its focus on “real” ingredients, the company added that it opted for sugar as its sweetener – but only 2 grams per can.
Spindrift also taps into the premiumization and clean ingredient trend with its use of fruit juice for flavor and sweetness.
Can ramped up health benefits boost RTD tea sales?
Tea – whether brewed or sold as loose leaf or in bags – has always had a health halo thanks in part to the natural antioxidants in the leaves, but some brands are positioning their products to more directly deliver the health benefits consumers increasingly want.
For example, PepsiCo launched Pure Leaf Mental Focus in April as “its first line of sparkling iced teas crafted with naturally occurring caffeine and added L-theanine to help support focus.
In July, newcomer Wipeout Tea, also made a bid for health-focused consumers with the launch of its Sweet Tea, Half-Pipe Lemonade + Tea and Unsweetened Black Tea, which combine brewed tea with 160 mg of caffeine and B vitamins. The functional tea brand is positioned as an alternative to energy drinks and initially focused on lifestyle accounts at gyms, sporting venues and campuses as well as c-stores and grocery chains, according to the Austin, Texas-based brand.
Will innovation and renovation translate to sustained growth?
As illustrated by the plethora of RTD tea launches in recent months, brands are betting flavors, function and formulation will revitalize the category by giving consumers another reason to reach for bottled and canned tea instead of other functional beverages, sodas and sparking waters.
But whether these strategies can reverse the category’s sluggish sales will depend on whether new formulations deliver on taste, novel flavors encourage repeat purchases and functional positioning gives consumers a reason to chose tea over other options.
Ultimately, the challenge for a mature category facing myriad pressure is whether it can turn new and novel into tried and true for sustained demand.
