วิธีทำชาเย็นแบบ Cold Brew: วิธีง่ายๆ

Cold brew tea is a refreshing, low-caffeine alternative to hot tea that's perfect for summer. Unlike traditional iced tea, which is brewed hot and then chilled, cold brew involves steeping tea leaves in cold water for an extended period. The result is a smoother, less bitter drink with a naturally sweet flavor.

In this guide, we'll walk you through the simple steps to make cold brew tea at home. You'll learn the ideal tea-to-water ratio, the best steeping times, and which teas work best for this method. Whether you're a green tea lover or prefer something richer, cold brew tea is an easy way to enjoy your favorite leaves.

Why Cold Brew Tea?

Cold brewing tea offers several benefits over hot brewing. Because the tea leaves are never exposed to hot water, fewer tannins are extracted, which means less bitterness and astringency. This makes cold brew tea naturally sweeter and smoother, so you can enjoy it without adding sugar or sweeteners.

Another advantage is the lower caffeine content. Cold water extracts caffeine more slowly than hot water, so cold brew tea contains about 50% less caffeine than its hot-brewed counterpart. This makes it a great choice for those who are sensitive to caffeine or want a soothing evening drink.

• Smooth and naturally sweet flavor
• Lower caffeine content
• Easy to prepare in large batches

Choosing the Right Tea

While you can cold brew almost any tea, some varieties shine more than others. Green teas, like our Jasmine Green Tea, produce a light, floral cold brew that's perfect for summer. White teas are also excellent, offering a delicate, subtle flavor. If you prefer something more robust, black teas like Breakfast Black Tea create a bold, malty cold brew that pairs well with milk.

Oolong and pu'er teas can also be cold brewed, but they may require a longer steeping time to develop their complex flavors. For a caffeine-free option, try herbal teas like passion fruit or chamomile. Our Passion Fruit Green Tea is a great choice if you want a fruity twist.

• Green and white teas for a light, refreshing brew
• Black teas for a stronger, more robust flavor
• Herbal teas for a caffeine-free option

Basic Cold Brew Tea Recipe

The basic ratio for cold brew tea is one teaspoon of loose leaf tea (or one tea sachet) per 8 ounces of cold, filtered water. You can adjust this to taste, but starting with this ratio ensures a balanced brew. Place the tea in a large jar or pitcher, add the water, and stir gently.

Cover the container and refrigerate for 12 to 18 hours. The longer you steep, the stronger the tea will be. After steeping, strain the tea leaves or remove the sachets. Your cold brew tea is now ready to serve over ice. It will keep in the refrigerator for up to three days.

• Use 1 teaspoon of tea per 8 oz of water
• Steep for 12-18 hours in the fridge
• Strain and serve over ice

Flavor Variations and Tips

Once you've mastered the basic cold brew, you can experiment with flavors. Add slices of citrus, berries, or fresh herbs like mint to the pitcher before steeping. You can also sweeten the tea with a simple syrup or honey after brewing, but the natural sweetness of cold brew often needs no additional sugar.

For a fun twist, try making a cold brew tea concentrate by using double the amount of tea. Steep for 18 hours, then dilute with water or milk when serving. This is perfect for making iced tea lattes or for when you want a quick glass of tea without waiting.

• Add fruits or herbs for extra flavor
• Make a concentrate for quick servings
• Use a sachet holder like The Codex Sachet Holder for easy cleanup
