HARIO Co., Ltd., a leading manufacturer of heatproof glass and specialty coffee equipment, today announced the U.S. launch of two new designs of its Cold Brew Tea Wine Bottle: Cold Brew Tea Wine Bottle “Aya” Series. While based on the original Cold Brew Tea Wine Bottle which features a removable strainer and a sleek wine‑bottle profile, the Aya Series introduces distinct Japanese‑patterned designs that give cold‑brew tea bottles a uniquely stylish, table‑ready appearance so they can be enjoyed at mealtime much like wine. The two new Aya series design bottles will be available to U.S. shoppers beginning September 24, through HARIO’s global website at https://globalhario.com/products/filter-in-bottle-pine-tree.

The product is available in two patterns inspired by traditional Japanese aesthetics: Cherry Blossom Blizzard and Wisteria.

Cold truths of conventional cold‑brew bottle presentation

Cold‑brewed beverages have grown in popularity not only for their refreshing taste but also for their ability to reduce bitterness by limiting the extraction of tannins. However, conventional cold‑brew tea bottles have frequently fallen short in presentation, often prioritizing function over visual appeal and appearing more like everyday household kitchenware than elegant tableware.

How HARIO addressed these visual presentation challenges of conventional cold-brew bottles

HARIO’s Cold Brew Tea Wine Bottle was originally developed to solve these presentation issues. Its body is crafted from HARIO’s proprietary heatproof glass, HARIO Glass®*, which preserves the purity and clarity of flavor. The polypropylene strainer rinses clean with minimal effort, avoiding the clogging and scrubbing.

To further elevate the everyday cold‑brewing experience and move beyond the mundane home‑use feel associated with conventional bottles, HARIO designed the Cold Brew Tea Wine Bottle with a sophisticated wine‑bottle silhouette. This elegant form evokes the quiet but special sense of occasion that comes with opening a fine wine. The design transforms cold‑brew preparation from a simple daily habit into a refined, aesthetically mindful ritual.

Building on this foundational concept, the new Aya Series versions of the Cold Brew Tea Wine Bottle were created to spread the exceptional taste and experience of cold‑brew tea to a wider audience by introducing traditional Japanese designs. Through the new cultural touch introduced by the new Cherry Blossom Blizzard and Wisteria designs, HARIO aims to make cold‑brewed tea visually captivating in any environment, whether blending seamlessly into casual daily routines or serving as an elegant centerpiece at the dining table.

Positioned discreetly beneath the lid rather than inside the bottle, the strainer remains nearly invisible, keeping the tea as the visual focal point and allows the Wisteria and Cherry Blossom Blizzard patterns to appear with uninterrupted elegance.

About Aya Series

The Aya Series is HARIO’s lifestyle line that brings together traditional Japanese design aesthetics and modern minimalism. First introduced internationally in October 2025, the series is designed to bring calm, clarity, and subtle beauty into everyday living through products that serve as both functional tools and understated interior accents.

Aya is shaped by three core aesthetics: Irodori, which introduces artistic vibrance into daily life; Yohaku, which embraces openness and invites personal interpretation; and Zeitaku, which encourages a lifestyle that values time, atmosphere, and quiet refinement.

In the U.S. market, the Aya Series currently includes V60 pour‑over coffee sets, drippers, servers, and glasses. The Cold Brew Tea Wine Bottle now joins the lineup as the newest addition to the collection.
