Experience the great taste of cold brew coffee on-the-go with the Primula 22 Oz. Cold Brew & Travel bottle. Cold brewing coffee over a longer period of time produces a smooth, flavorful taste that is 65% less acidic than hot-brewed coffee. Preparing cold brew coffee is easy- just add coffee grounds, pour cold water slowly over the coffee and then brew in the fridge for 24 hours. Cold brew will stay fresh up to 14 days in your fridge. To add coffee, just unscrew the bottom base, add your coffee to the stainless steel filter and re-attach the base. Tritan Plastic Bottle, lid and removable micro filter are top rack dishwasher safe. Try adding even more flavor by mixing in cinnamon, coconut or ginger with your coffee grounds before cold brewing, or add citrus zest, mint or lavender after brewing.
