1. Introduction
Cold brew green tea is a refreshing, smooth, and healthful beverage that is quickly gaining popularity among tea enthusiasts. Unlike traditional hot tea, which can sometimes taste bitter or astringent, cold brewing extracts flavors slowly, resulting in a naturally sweeter and milder taste. This method involves steeping loose tea leaves or tea bags in cold water for an extended period, usually overnight in the refrigerator.
One of the biggest advantages of cold brew green tea is its high antioxidant content. Green tea is packed with catechins and EGCG (epigallocatechin gallate), which support heart health, metabolism, and overall well-being. Additionally, cold brewing reduces acidity and tannins, making it gentler on the stomach while still delivering a refreshing and hydrating drink.

Whether you’re looking for a cool summer drink or a nutrient-packed daily beverage, cold brew green tea is a delicious and easy-to-make option.
2. What is Cold Brew Green Tea?
Cold brew green tea is a method of brewing green tea by steeping loose tea leaves in cold water for an extended period, usually overnight in the refrigerator. Unlike traditional hot brewing, which uses boiling water to quickly extract flavors, cold brewing allows the tea to infuse slowly, resulting in a smoother, naturally sweet taste with lower bitterness.
How It Differs from Hot Brewing
Hot brewing extracts flavors rapidly by exposing tea leaves to high temperatures, which can release more tannins and caffeine, leading to a bolder but sometimes bitter or astringent taste. In contrast, cold brewing:
Minimizes bitterness – Cold water prevents excess tannin extraction.
Enhances sweetness – Slow infusion highlights the tea’s natural floral and grassy notes.
Reduces acidity – Cold brew green tea is gentler on the stomach.
Retains antioxidants – Catechins and other beneficial compounds remain intact.
Since the tea leaves steep for several hours (typically 6-12) before straining and serving, they release flavors gradually and evenly, creating a light and refreshing drink. Cold brewing is also more forgiving—you won’t have to worry about over-steeping and getting a bitter taste.
For the best results, choosing the right type of green tea is essential. Some varieties work better for cold brewing than others. (Learn more in the Best Cold Brew Green Tea Varieties section.)
3. Benefits of Cold Brew Green Tea
Cold brew green tea is more than just a refreshing drink—it offers numerous health benefits while maintaining a smooth, naturally sweet taste. Unlike traditional hot brewing, cold brewing preserves essential antioxidants, reduces bitterness, and enhances the tea’s natural flavors. Here’s why you should consider adding cold brew green tea to your daily routine:
Gentler on the Stomach
Hot-brewed green tea can sometimes be harsh on the stomach due to its high tannin content, which increases acidity and may cause discomfort. Cold brewing extracts fewer tannins, resulting in a milder, less acidic tea that’s easier on digestion.
Higher Antioxidant Content
Green tea is packed with catechins, flavonoids, and EGCG (epigallocatechin gallate)—powerful antioxidants that support heart health, immune function, and cellular protection. Cold brewing helps retain these beneficial compounds, as they are less likely to break down at lower temperatures.
Smoother and Naturally Sweeter Taste
One of the main reasons tea lovers prefer cold brew green tea is its smooth, refreshing flavor. Without the heat-extracted bitterness, the natural floral, grassy, and slightly sweet notes of green tea become more pronounced. This makes it an excellent option for those who find hot green tea too strong.
Hydration Benefits
Cold brew green tea is a calorie-free and sugar-free beverage that helps keep you hydrated. Unlike sugary sodas or artificially flavored drinks, it provides a natural and healthy way to increase water intake while enjoying a light and flavorful drink.

Supports Weight Loss and Metabolism
The EGCG and catechins in green tea are known to boost metabolism and aid fat oxidation. Cold brew green tea still contains these compounds, making it a great choice for those looking to support weight management while staying hydrated.
With all these benefits, cold brew green tea is a delicious and nutritious addition to any lifestyle. Whether you drink it for its health properties or its refreshing taste, it’s an easy and enjoyable way to stay hydrated and energized.
According to research, catechins in green tea have been linked to improved heart health and metabolic benefits.
4. How to Cold Brew Green Tea (Step-by-Step Guide)
Cold brewing green tea is a simple and hassle-free process that requires minimal effort while delivering maximum flavor. By using cold water and a long steeping time, you can create a smooth, refreshing, and naturally sweet tea without the bitterness of hot brewing. Follow this step-by-step guide to make the perfect cold brew green tea at home.
Choosing the Right Tea
The quality of your tea directly affects the taste of your cold brew. You can use either loose-leaf green tea or pre-packaged tea bags, but some varieties work better than others:
✔️ Best Loose-Leaf Green Teas for Cold Brewing: Sencha, Gyokuro, Dragon Well, or Bancha. These varieties have a naturally sweet and mild flavor.
✔️ Top Green Tea Bags for Cold Steeping: Choose brands that use high-quality, whole-leaf tea rather than crushed or powdered varieties for the best flavor.
Pro Tip: Opt for organic green tea to avoid pesticides and additives that can affect the taste and quality of your brew.
Cold Brew Green Tea Ratio
The ideal ratio for cold brew green tea is 1:50, meaning:
- 1 gram of tea per 50 ml of water
- 1 tablespoon (about 5g) of loose-leaf tea per 2 cups (500 ml) of water
- 1 standard tea bag per 8-10 oz (240-300 ml) of water
Adjust the amount based on your preferred strength.
Brewing Process
Follow these easy steps to make your cold brew green tea:
Step 1: Add green tea leaves or tea bags to a glass pitcher, mason jar, or cold brew bottle.
Step 2: Pour cold, filtered water over the tea. Using filtered water enhances the flavor.
Step 3: Cover and refrigerate for several hours (typically 6-12) before straining and serving. Longer steeping times result in a stronger flavor.
Step 4: Strain the tea (if using loose leaves) and serve chilled.
Optional Additions for Extra Flavor
Enhance your cold brew with natural ingredients:
🍋 Lemon or lime slices – Adds a refreshing citrus twist.
🌿 Fresh mint or basil – Boosts the cooling effect.
🍯 Honey or agave syrup – A natural sweetener for extra smoothness.
🍓 Berries or cucumber – Infuses a fruity or spa-water vibe.
Cold brew green tea can be stored in the refrigerator for up to 3 days, making it a perfect grab-and-go drink for any time of the day.
5. Best Cold Brew Green Tea Options
Choosing the right type of green tea is essential for making a smooth, flavorful, and refreshing cold brew. While most green teas can be cold brewed, some varieties yield better taste and aroma. Here are the best options for loose-leaf and bagged teas, along with the benefits of choosing organic over conventional.
Best Loose-Leaf Green Teas for Cold Brewing
Loose-leaf green tea provides the freshest flavor and highest quality, making it the best choice for cold brewing. The following varieties work exceptionally well:
Sencha: A popular Japanese green tea with a light, grassy flavor and natural sweetness.
Dragon Well (Longjing): A Chinese green tea with a smooth, nutty, and slightly roasted taste.
Gyokuro: A premium Japanese green tea known for its umami-rich and delicate sweetness.
These teas release a balanced, non-bitter flavor when cold brewed, making them perfect for a refreshing drink.
Best Cold Brew Green Tea Bags
If you prefer convenience, many brands offer pre-packaged cold brew green tea bags designed for optimal extraction in cold water. Look for:
Ito En Oi Ocha – A high-quality Japanese green tea brand.
Twinings Cold Infuse Green Tea – Specially formulated for cold brewing.
Harney & Sons Japanese Sencha – Delivers a smooth and naturally sweet flavor.
Make sure the tea bags contain whole or high-quality leaves, not crushed or powdered tea, for the best taste.
Organic vs. Conventional Green Tea
Organic green tea is grown without synthetic pesticides or chemicals, preserving its natural flavors and health benefits. Choosing organic ensures:
Higher antioxidant content
Better taste and aroma
Fewer harmful residues
While conventional teas can still make great cold brews, organic options provide a cleaner, more authentic taste.

6. Cold Brew Green Tea Caffeine Content
Many tea drinkers ask whether cold-steeped green tea contains caffeine. The answer is yes, but its caffeine content is typically lower than that of hot-brewed tea due to the slower extraction process. Since caffeine dissolves more readily in hot water, cold steeping results in a gentler, more gradual release of caffeine over time.
Factors Affecting Caffeine Levels
Several factors influence the caffeine content in cold brew green tea:
✔️ Tea Variety: Different green teas contain varying amounts of caffeine. For example, Gyokuro has more caffeine than Sencha or Bancha.
✔️ Steeping Time: The longer the tea steeps, the more caffeine is extracted—though cold brewing still results in lower caffeine than hot brewing.
✔️ Leaf-to-Water Ratio: Using more tea leaves per cup will increase caffeine concentration.
On average, an 8 oz cup of cold-brewed green tea contains 15–30 mg of caffeine, whereas the same tea, when brewed with hot water, typically has 30–50 mg per cup.
Cold Brew Green Tea vs. Other Beverages
How does the caffeine content of cold brew green tea compare to other popular drinks?
Beverage | Caffeine per 8 oz (approx.) |
---|---|
Cold Brew Green Tea | 15–30 mg |
Hot Green Tea | 30–50 mg |
Black Tea | 40–70 mg |
Cold Brew Coffee | 100–200 mg |
Regular Coffee | 95 mg |
Cold brew green tea is a mildly caffeinated beverage, making it an excellent choice for those looking to reduce caffeine intake while still enjoying a gentle energy boost.

7. Cold Brew Green Tea vs. Hot Brew Green Tea
While both cold brew and hot brew green tea come from the same leaves, their flavor, nutrition, and caffeine content can vary significantly due to the difference in brewing methods. Understanding these differences can help you choose the best brewing style based on your preferences and needs.
Flavor Differences
One of the biggest reasons people love cold brew green tea is its smoother, naturally sweeter taste. Cold water extracts flavors slowly and gently, which:
Reduces bitterness and astringency
Enhances mild, floral, or grassy notes
Creates a refreshing and crisp taste
In contrast, hot brew green tea releases flavors rapidly, often resulting in a stronger, bolder, and sometimes slightly bitter taste due to higher tannin extraction.
Nutritional Differences
Cold and hot brewing extract different compounds from green tea:
Cold brewing preserves delicate antioxidants, including catechins and EGCG, which can degrade in hot water.
Hot brewing extracts more caffeine, making it a better option if you need an energy boost.
Hot tea releases more L-theanine, an amino acid that promotes relaxation.
Best Use Cases: When to Choose Each Method
✔️ Choose cold brew green tea if you want a mild, refreshing, and hydrating drink with lower caffeine.
✔️ Choose hot brew green tea if you prefer a stronger taste and a quick caffeine boost.
Both methods have their benefits, and trying both can help you find your perfect cup!
