When I was fishing up in NorCal last year, I met a guy that used these cotton sacs to brew coffee. He would just fill it with grounds, drop it in his thermos, and then add water all day. I wanted to try this method to brew tea, so I recently bought some from etsy.com. You can also fill a sac with herbs and use it to flavor soups. I’m going dedicate one for coffee and one for each type of tea so they get flavored nicely over time. This is going to be perfect for backpacking or any day trip where you want to travel light and still have a nice beverage.
