FourSix makes brewing pour over coffee easy. There are countless ways to brew coffee. For coffee enthusiasts, sometimes these methods can get... complicated. And following a more complex recipe can be difficult, especially in the morning when you haven't had your coffee yet. Part calculator, part timer, FourSix is designed to take a complicated method for pour over and make it simple and easy, even if you're still not completely awake. Named after the 4:6 method invented by Tetsu Kasuya, FourSix will create a custom pulse pour recipe based on 3 simple questions - Do you like your coffee sweeter or brighter? How do much do you want to extract your beans? And what size? Instantly, you'll see how each pulse-pour will break down, and how they affect your final cup. When you're ready to start, simply follow along with the Timer telling you exactly how much to pour and when. Not only will you get a great cup of coffee, but you'll be able to do it again the next morning. To use FourSix, you'll need a Hario V60 and a scale that measures in grams. Additional helpful tools include a pouring kettle with a narrow spout and a thermometer to test water temperature. If you like FourSix, but want even more, you'll want FourSix Pro. - Get extra settings so you can dial in your perfect brew exactly how you like.  - Record every brew and make notes, ratings, and track your coffee beans.  - Get notifications about your coffee cooling to the perfect temperature.

Love every coffee you buy. Scan any coffee bag and Siip shows how well it matches your taste, and why. At the grocery store, at a café or at home, you'll know if you'll like it before you buy it. Most of us know what we like when we taste it, but can't say why. So we buy the same safe bag again, or gamble on the packaging. Siip learns your taste from what you actually drink, not from what you think you like. That matters: people most often say they like chocolate and nutty coffees, yet they rate floral and berry coffees higher. HOW IT WORKS 1. Scan the bag. Siip reads the label from a photo and knows more than 50,000 coffees from 6,000+ roasters. 2. See your match. Get a match score and the reasons a coffee fits you, or doesn't. 3. Rate it. Answer one question: "How was this coffee?" Every rating makes your next match sharper. WHAT YOU CAN DO WITH SIIP • Scan or search any coffee before you buy it • See why a coffee suits you, in plain words • Rate coffees from anywhere: a bag at home, a café cup, a box from Siip • Get your taste in words: the flavors, roasts and origins you rate highest • Get picks made for your taste • Keep track of every coffee you've tried and loved • Meet the roasters and farmers behind your cup No coffee knowledge needed. Just tell Siip whether you liked it. THE SIIP SUBSCRIPTION (US ONLY) Let Siip pick for you. Each box brings coffees matched to your taste from 29 independent roasters, including Onyx Coffee Lab, Equator Coffees and George Howell Coffee. Siip picks from each roaster's full catalog and learns from every coffee you rate, not only the ones we send. By the fourth box, subscribers like or love 86% of their coffees. Free shipping. Skip, pause or cancel anytime. "If you asked me six months ago what coffees I like, my answer would have been dark roast with a bunch of cream. Now, I'd tell you it's probably somewhere from Nicaragua, probably a medium roast, with notes of nuts or chocolate." Richie, Siip subscriber Join 10,000+ coffee drinkers on Siip.
