1. Cold Brew Coffee and Its Types

Cold brew coffee is made by steeping coarsely ground coffee beans in water at room temperature or lower for a period of time (usually 12 to 24 hours). This method slows the extraction rate, resulting in a beverage with a rich, full-bodied flavor and less acidity than hot brewed coffee. There are several types of cold brew coffee to choose from, including:

• Classic cold brew coffee: Made using standard steeping methods.

• Nitro cold brew coffee: Infused with nitrogen to create a creamy texture similar to draft beer.

• Cold brew espresso: A stronger version that is diluted before drinking.

• Flavored cold brew coffee: Infused with various flavors, such as vanilla, chocolate, or fruit extracts.

Common packaging forms of cold brew coffee include the following:

• Tetra Pak cartons: A more environmentally friendly packaging method, with a longer shelf life and no need for refrigeration, it is popular with consumers;

• Glass bottles: Usually used for high-end products, they are visually attractive but less portable.

• Plastic bottles: Lightweight and easy to carry, ideal for on-the-go consumption.

• Cans: Durable, easy to recycle, and easy to carry

The necessity of steaming and sterilizing cold brew coffee: Using a high temperature and high pressure sterilizer to sterilize cold brew coffee can kill bacteria and harmful microorganisms in the beverage, extend the shelf life of coffee products, ensure beverage safety, enhance the taste, texture and flavor of coffee beverages, and increase consumers' desire to buy.
