BJC-owned Oishi Green Tea has long dominated Thai convenience-store shelves, and its latest price and pack-format moves show how a mature drink brand is trying to stay relevant in a market shaped by sugar taxes and health-conscious consumers. The ready-to-drink tea line, led by the 380 ml PET bottle in flavors such as original honey lemon and genmaicha, targets mass-market buyers at a typical street price of around THB 20 in Thailand’s 7-Eleven and Big C networks.

Oishi Green Tea’s role inside BJC’s beverage portfolio

Oishi Group, consolidated under Berli Jucker Public Company, built Oishi Green Tea into one of Thailand’s best-known ready-to-drink beverages after launching the line in the early 2000s and extending it into multiple flavors, low-sugar variants and larger PET formats for family consumption. The beverage business is reported within Oishi’s food and beverage segment, where the ready-to-drink teas account for a significant share of sales alongside the restaurant operations, and where competition includes F&N’s 100PLUS-linked teas and Suntory’s ready-to-drink entries.

Packaging remains central to the brand’s positioning: the mainstream 380 ml PET bottle is complemented by larger 500 ml and 1.5 liter formats, as well as multipacks aimed at modern trade channels, while the company has also experimented with paper-based and slim-can options in export markets. On the formulation side, Oishi has pushed reduced-sugar and zero-sugar recipes to lessen the impact of Thailand’s tiered sugar tax, while keeping the core taste profile of the flagship sweetened green tea that made the brand popular in the first place.

Pricing has been adjusted gradually rather than in sharp steps, with list prices for single 380 ml bottles typically advertised in the THB 20 to THB 22 range in Thai retail, and heavier discounting used in hypermarkets and promotions to defend volume in the face of rising PET and sweetener costs. For investors, the key question is how far BJC can pass on input-cost inflation without losing share to rivals like Ichitan, which has aggressively promoted its own ready-to-drink teas with similar pack sizes and price points in the Thai mass market.

Within BJC’s broader consumer-products business, Oishi Green Tea is strategically important because it helps secure shelf space, cross-promotions and co-marketing with other BJC brands across convenience and modern trade formats operated or supplied by the group. The brand also serves as a test bed for new sweetener systems and packaging-lightweighting that can later be applied to other beverages in the portfolio, tying product decisions to both regulatory pressure and cost discipline.

For equity holders, Oishi’s beverage performance is one of several moving parts inside Berli Jucker Public Company, which is listed on the Stock Exchange of Thailand; the group’s shares (ISIN TH0725010000) closed in Bangkok at THB 29.75 on 06/14/2026, reflecting investor expectations for stable consumer demand and disciplined capital spending in its retail and packaging operations.
