Your first month is free, enough to take this course at no cost. ## A trainer's approach, not a barista's trick list Michael Phillips teaches from Blue Bottle's own coffee bar, and the course reflects how a training director actually thinks: start with the mechanism, then hand over the tools to control it. Coffee Theory is the pivot lesson. Rather than offering brewing tips as folklore, Phillips explains that hot water acts as a solvent pulling soluble material from ground coffee, that total dissolved solids measures strength, and that extraction between 18 and 22 percent is the industry's accepted sweet spot. He then maps that onto the brew control chart, an axis of strength against extraction that turns "this tastes off" into a diagnosis: over 22 percent reads as bitter, under 18 percent reads as sour. That single reframe is what elevates this above a typical how-to video, because it gives the viewer a corrective loop rather than a recipe to memorize blindly. The course does not stay abstract for long. Brewing Tools walks through a burr grinder, a pouring kettle with a narrow spout, a digital scale, and a bonmac dripper with bamboo filters, explaining what each does and why a blade grinder in particular should be avoided for its inconsistent particle size. Selecting Your Ingredients covers the difference between blends and single-origin coffees, how to read a bag for producer group, varietal, and roast date, and why coffee brewed two to four months past roasting has lost most of its character. ## The recipe and the pour, made replicable Making Your Recipe is where the course earns its usefulness. Phillips builds a formula from two numbers: total water weight and a coffee-to-water ratio, landing on 350 grams of water divided by a 1:14 ratio for 25 grams of coffee. He explains why Blue Bottle uses a stronger 1:11 ratio for blends meant to take milk and a lighter 1:15 for single origins meant to show nuance, which gives the viewer a rationale for adjusting the ratio rather than a fixed number to copy. Brewing Your Coffee then executes that recipe as a four-pour technique: a 45-to-55-second bloom to release roasting gases, followed by three staged pours to 150, 250, and 350 grams, with visual cues like the "shoreline" and the evenness of the grounds bed used to self-correct pouring technique. Tasting Coffee and Enjoying Your Brew close the course with a five-category tasting framework (sweetness, body, finish, acidity, flavor) and a practical suggestion to taste side by side with fruit for calibration. This section is honest about its own optional nature, and it works as a light capstone rather than padding. The course is unmistakably built around pour-over with a bonmac dripper, so viewers committed to French press, AeroPress, or espresso get comparatively little. It also assumes a real equipment budget: a burr grinder, digital scale, and pouring kettle are all treated as near-mandatory. Within that scope, though, the explanation of why each variable matters, not just what to do, makes this worth more than its short runtime suggests. The standout The percentage-of-extraction and brew control chart lesson, which turns vague taste complaints like 'too bitter' into a specific, correctable grind adjustment. ## What you will learn - · How to read a brew control chart to distinguish over-extraction (bitter) from under-extraction (sour) - · How to build a personal recipe using a coffee-to-water ratio (e.g. 1:14) rather than eyeballing scoops - · How to choose a burr grinder and adjust grind size to correct extraction problems - · How to read single-origin coffee labels for producer, varietal, and roast date - · How to execute a four-pour pour-over technique including the bloom stage - · How to taste coffee systematically across sweetness, body, finish, acidity, and flavor Best for: Home coffee drinkers ready to move past a drip machine and willing to buy a scale, burr grinder, and pour-over kit. Skip it if: Anyone wanting espresso instruction, French press-only brewers uninterested in pour-over, or those unwilling to buy a digital scale and grinder.
