Starbucks Cold Brew: How It’s Made and Why It’s Limited

When summer heat hits and you crave a smooth, refreshing coffee without acidity or bitterness, cold brew often comes to mind. But not all cold coffee is created equal—especially not when it’s been steeped in water below 5°C for over 20 hours. That’s the story behind Starbucks’ exclusive cold brew in China this summer, a drink that’s more method than beverage.

The answer is simple: Starbucks’ cold brew is made by steeping rare Peruvian coffee beans in water under 5°C for over 20 hours. Only 19 Starbucks Reserve locations in China serve it, and some sell out by 3 PM. That’s the craft, the scarcity, and the taste in a nutshell.

What Is Starbucks Cold Brew in China?

Starbucks has introduced a special cold brew coffee in China this summer, available exclusively at 19 of its Reserve stores. This isn’t your standard iced coffee—it’s a slow-steeped, 20-plus-hour cold water extraction using select beans. Served plain, with no milk or sugar, it highlights clarity, subtle sweetness, and a clean finish. The result is a smooth, refreshing drink designed to showcase coffee’s innate flavours without masking them.

The Science Behind 20-Hour Cold Extraction

According to Starbucks’ coffee master Zhang Kai, crafting this cold brew is far from simple. The recipe involves careful selection of beans, precise control of water temperature (below 5°C), extended extraction time (over 20 hours), and specific equipment. All variables were tested repeatedly by Starbucks’ global R&D team to stabilise flavour, balance acidity, and preserve aroma.

This long, cool brew cycle mellows the coffee’s sharp edges while extracting a wide range of flavour compounds slowly and evenly. The technique avoids the over-extraction or bitterness common in hot brewing, resulting in a cleaner cup with pronounced sweetness and soft acidity.

Why This Specific Peruvian Coffee Bean?

The first batch of Starbucks cold brew in China uses a single-origin bean dubbed the 'Warrior Bean': the Peru Amazon Reserve. This bean is among the few selected by Starbucks’ global team specifically for cold brewing. It brings a balanced profile capable of holding up to the prolonged cold steep without losing complexity.

Peruvian coffees are often known for their mild acidity and nutty chocolate notes, but this particular lot was chosen for its ability to shine in cold brew—offering a clean, sweet base that pairs well with the extended extraction method. The extended brew time allows deeper extraction of sugars and subtle fruit undertones without harshness.

How Limited Is This Cold Brew?

Due to the time-intensive process and the use of high-quality single-origin beans, production is tightly constrained. The cold brew is only available at 19 Starbucks Reserve locations nationwide. Even flagship outlets like the one in Beijing’s Kerry Center have limited daily stock—some run out as early as 3 PM. Demand clearly exceeds supply, adding to its exclusive appeal.
