This press uses a patented 3-in-1 technology that combines the best of several brew methods into one, easy-to-use, very portable device. Because it combines the best of 3 methods, you get a cup that is full bodied like a French press, smooth and complex like when using the pour-over method and rich in flavor like espresso.As I wrote in The 4-Hour Chef: “This is now, bar none, my favorite brewing method.” And now they have a new Crystal Clear version—sleek enough for display and tough enough for the road. Pick one up at AeroPress.com/Tim for less than $50.*This episode is also brought to you by Athletic Greens. I get asked all the time, “If you could use only one supplement, what would it be?” My answer is usually AG1 by Athletic Greens, my all-in-one nutritional insurance. I recommended it in The 4-Hour Body in 2010 and did not get paid to do so. I do my best with nutrient-dense meals, of course, but AG1 further covers my bases with vitamins, minerals, and whole-food-sourced micronutrients that support gut health and the immune system. Right now, Athletic Greens is offering you their Vitamin D Liquid Formula free with your first subscription purchase—a vital nutrient for a strong immune system and strong bones. Visit AthleticGreens.com/Tim to claim this special offer today and receive the free Vitamin D Liquid Formula (and 5 free travel packs) with your first subscription purchase! That’s up to a one-year supply of Vitamin D as added value when you try their delicious and comprehensive all-in-one daily greens product.*For show notes and past guests on The Tim Ferriss Show, please visit tim.blog/podcast.For deals from sponsors of The Tim Ferriss Show, please visit tim.blog/podcast-sponsorsSign up for Tim’s email newsletter (5-Bullet Friday) at tim.blog/friday.For transcripts of episodes, go to tim.blog/transcripts.Discover Tim’s books: tim.blog/books.Follow Tim:Twitter: twitter.com/tferriss Instagram: instagram.com/timferrissYouTube: youtube.com/timferrissFacebook: facebook.com/timferriss LinkedIn: linkedin.com/in/timferrissPast guests on The Tim Ferriss Show include Jerry Seinfeld, Hugh Jackman, Dr. Jane Goodall, LeBron James, Kevin Hart, Doris Kearns Goodwin, Jamie Foxx, Matthew McConaughey, Esther Perel, Elizabeth Gilbert, Terry Crews, Sia, Yuval Noah Harari
