How to Make Oi Ocha (Green Tea Bottle) – Traditional & Healthy Version
Oi Ocha (お～いお茶) is Japan’s most beloved bottled green tea, celebrated for its refreshing taste and deep umami notes. Originating from the tradition of brewing sencha, Oi Ocha captures the essence of Japanese tea culture, offering a convenient and health-conscious way to enjoy authentic ryokucha (緑茶). The name translates to 'Hey, Tea!' and reflects the inviting spirit of Japanese hospitality, where tea is offered to welcome guests or to find a moment of calm in a busy day. Traditionally enjoyed chilled or at room temperature, Oi Ocha is made with premium sencha leaves, prized for their vibrant green hue and delicate, grassy aroma. This beverage is popular across Japan in every season, from hanami (cherry blossom viewing) picnics in spring to the summer heat, and is a staple at home, in offices, and on-the-go. Making your own Oi Ocha at home allows you to control the quality and strength, ensuring a pure, additive-free drink packed with antioxidants and natural flavor. With its clean, invigorating taste, this green tea beverage is a perfect choice for anyone seeking a zero-calorie, vegan, and refreshing drink that embodies the spirit of Japanese wellness.
材料(1 bottle (350ml) per serving分)
- 2 tbsp Sencha green tea leaves (煎茶, high-quality loose-leaf recommended)
- 800 ml Filtered water (Soft water preferred)
- 1 cup Ice cubes (氷, for rapid chilling)
- 1 tsp Yuzu peel (柚子, thinly sliced (optional, for aroma)) - オプション
- 1 leaf Fresh shiso leaf (紫蘇, for garnish (optional)) - オプション

- few petals Sakura petals (桜, for seasonal presentation (optional)) - オプション
作り方
- 1
Boil filtered water and allow it to cool to 80°C (176°F). This temperature is ideal for extracting umami from sencha without bitterness.
5 minutes
Always use soft, filtered water for best flavor clarity.
- 2
Add sencha leaves to a kyusu (Japanese teapot) or a heat-resistant glass pitcher.
2 minutes
Pre-warm the teapot with hot water, then discard to maintain optimal brewing temperature.
- 3
Pour the hot water over the tea leaves. Allow the leaves to steep for 1.5–2 minutes for a balanced umami and slight astringency.
2 minutes
Avoid over-steeping to prevent bitterness. Swirl gently for even extraction.
- 4
Strain the tea into a clean pitcher, pressing gently on the leaves to extract all the liquid. Discard the leaves or reserve for a second infusion.
3 minutes
Do not squeeze too hard; light pressure ensures clarity and smoothness.
この料理が健康的な理由
Oi Ocha is a healthy beverage due to its zero calorie content, high antioxidant levels, and natural composition. It supports weight loss, boosts metabolism, and provides gentle, sustained energy without the crash of sugary drinks. Its vegan and gluten-free profile makes it suitable for most diets. By avoiding sweeteners and additives, you enjoy the pure flavor and health benefits of traditional Japanese green tea.
Sencha green tea is naturally calorie-free, vegan, and packed with catechins, a type of antioxidant known for supporting heart health and metabolic function. It is also a source of vitamins C and E, potassium, and amino acids such as theanine, which may promote relaxation and concentration. The minimal processing of sencha preserves these nutrients, and the addition of yuzu peel or shiso adds vitamin C and anti-inflammatory compounds. With zero fat, sugar, or artificial additives, homemade Oi Ocha is a superb hydration choice.
