If you want to try cold brew coffee at home without buying any special equipment, these Green Mountain cold brew coffee bags let you make it with a regular pitcher.
Just toss a couple of bags into your pitcher with four cups of water, steep in the fridge for 8-12 hours, and then add three more cups of water when you’re done. Today only, $22 gets you enough bags to make eight pitchers today, down from the usual $40. Anyone who makes cold brew knows that it takes a lot of coffee to do it properly, so $2.73 for an entire pitcher is an incredible value.
