It’s been close to 100°F for the past couple days, so rather than use my trusty AeroPress to make hot coffee for mid-morning at work (this needs its own post to document the tweaks I use) I made a batch of cold brewed coffee.
Hot brewing heats up the oils and can result in a much more acidic taste that gets bitter as it ages – so unless you plan to drink it immediately over ice, making a large pot of hot coffee then chilling is not going to be great the next day.
Cold brewing is a great alternative to making hot coffee and then cooling it, as long as you remember to start your batch about 24 hours before you want it to drink. Soaking the grounds releases flavors without becoming bitter, and the resulting beverage can be refrigerated for several days without deteriorating in taste.
You can buy many fancy and expensive special devices for cold brewing, but all you really need is a large jar (e.g., a 32 oz mason jar) and something to strain the grounds through, which can be a paper coffee filter lining a mesh strainer.
