Iced Tea and Cold Brew Blends for Private Label

Iced tea and cold brew have moved from a summer sideline to a year-round category on retail shelves and marketplace search bars, and buyers keep asking a version of the same question: does this need a different tea bag? Mostly, no. What actually changes between a hot-brew product and a cold-brew one is the blend itself — what is in the bag, how it is cut, and how strong the result needs to be when there is no boiling water doing the extraction work.

A trend built on convenience, not a new format

The growth in iced tea and cold brew is driven by how people want to drink it: straight from a bottle, a jug in the fridge, or a bag dropped into a glass of water overnight. None of that requires a new bag construction. A standard string-and-tag bag with a paper tag, individually wrapped in its own envelope, works the same way in cold water as it does in hot — it is the recipe inside that has to be designed for the job. Framing the category this way keeps a private label brand's claims honest and avoids promising a "cold-brew mesh" or similar feature that does not exist in the product.

Blends that extract well without heat

Not every tea performs the same way when steeped cold. Hibiscus-led fruit blends, mint, and many green teas give up their colour and flavour readily in cold water, which is why they dominate the bottled and jug iced tea aisle. Black tea can work too, though tannins can read as harsher without the rounding effect of heat. Delicate florals and some white teas are the trickiest: left to steep passively in a cold glass, they can taste thin, so a brand building a cold-brew line usually needs to test its existing hot-brew recipes rather than assume they translate directly.

This is a starting orientation, not a fixed rule — the only reliable answer for a specific recipe comes from tasting it cold.

Cut size, grammage and strength

Cold extraction is slower than hot extraction, so a blend that tastes right in three minutes of boiling water may taste weak after an hour in the refrigerator. Two levers help close that gap: a finer, more uniform cut that increases surface area, and a higher fill weight per bag. TeraVella's bagging line runs an adjustable dose — for example in the 1.5 to 3 g range — which gives a private label brand room to specify a heavier fill for a cold-brew SKU without changing the bag format itself. Getting this right is a formulation decision, confirmed through tasting, not a default setting.

Labelling "iced tea" and "cold brew" without overreaching

Both terms describe how the product is prepared, and the safest label is one that matches that preparation exactly: recommended water volume, fridge time, and whether the bag can also be used hot. Avoid implying a special cold-extraction technology or a process the product does not actually use. Wording rules for beverage claims differ by destination market, so route final label language through the competent authority or a regulatory adviser for each country before the artwork is locked.

Testing before committing to a production run

Because cold steeping is forgiving of small recipe changes but unforgiving of guesswork, the sensible path is to trial a handful of candidate blends at the exact grammage, water ratio and steep time planned for the finished product, then taste them cold, not warm. Comparing a hot-brew reference cup against several cold-brew variants of the same base blend usually reveals quickly which recipe needs more fruit, more mint, or a finer cut to hold up. That reference recipe, once approved, is what gets locked into the production specification.

Bringing a cold-brew SKU to a contract packer

None of this requires sourcing a new supplier relationship if a brand is already working with a contract tea bag manufacturer — it requires a clear brief. TeraVella packs herbal, fruit, black and green teas, as well as a customer's own blend, into string-and-tag bags with paper tags and individual envelopes on a line running at roughly 1,000 bags per hour in Antalya, under ISO 9001 and ISO 22000 with HACCP principles applied. For a cold-brew or iced tea launch, the useful next step is simply to state the target grammage and cut alongside the usual private label brief, with MOQ and lead time confirmed at quotation.
