Dial In Your xBloom Studio Using Copilot Mode

Copilot mode is where the xBloom Studio starts to feel like your machine rather than a pre-programmed appliance. It's how you brew with your own beans, build your own recipes, and adjust every variable to suit the coffee you're working with.

Most people who buy the Studio start with xPods in Autopilot mode, which is a great way to get familiar with how the machine brews. But once you're ready to bring your own coffee and start dialling things in, Copilot mode is where the real depth of the Studio opens up. This guide covers how to set up a recipe from scratch, which variables matter most, how to read your cup and adjust accordingly, and when to reach for the secondary controls like RPM and pour pattern.

What Copilot Mode Actually Does

In Copilot mode, you build a recipe in the xBloom app and the machine executes it. You control grind size, dose, ratio, water temperature, number of pours, pour volume, flow rate, pour pattern, and grinder RPM. The Studio handles the grinding, timing, temperature, and pouring precisely to your specification.

The xBloom Omni Dripper replaces the xPod dock for Copilot brewing. You fit a filter paper into the Omni Dripper, attach it to the brew arm, weigh out your beans using the built-in scale and the magnetic dosing cup, add them to the grinder, and then start the recipe from the app. From that point the machine takes over.

You can also save up to three recipes directly on the machine for use without your phone, which is useful once you've dialled in a recipe you're happy with for a particular coffee.

Starting a Recipe from Scratch

When you're working with a new coffee for the first time, starting with a simple and repeatable base recipe gives you something concrete to adjust from. The goal in the first few brews is not to find the perfect cup immediately, but to understand how the coffee responds so you can move in the right direction.

A practical starting point for most filter-roasted coffees on the xBloom Omni Dripper paired with the xBloom Filter Papers:

• Dose: 15g
• Ratio: 1:16 (240ml total water)
• Grind size: setting 35 to 40
• Water temperature: 90°C to 93°C
• Pours: 3 pours
• Pour 1 (bloom): 45ml, wait 30 to 45 seconds
• Pour 2: 100ml
• Pour 3: 95ml
• RPM: 90 (mid-range)
• Pour pattern: spiral

This isn't a definitive recipe. It's a starting point with enough structure to produce a drinkable cup while giving you a baseline to adjust from. Brew it once and taste it before changing anything.

The Variables That Matter Most

The xBloom Studio gives you a lot of control, which can feel overwhelming if you try to optimise everything at once. In practice, a small number of variables have the most influence on how your cup tastes. Start with these before touching anything else.

Grind Size

Grind size is the single most impactful variable in Copilot mode. It controls how quickly water passes through the coffee bed and directly determines how much flavour is extracted. Too fine and the coffee over-extracts, tasting bitter and harsh. Too coarse and it under-extracts, tasting sour, thin, or sharp.

For most filter coffees on the Omni Dripper, a grind size between settings 30 and 45 is a useful working range. Lighter roasts are denser and generally need a finer setting to extract properly. Darker roasts extract more easily and often need a coarser setting to stay clean and balanced. Start in the middle of your expected range and adjust based on taste after your first brew.

Dose and Ratio

The dose is how much coffee you're using, and the ratio determines how much water brews through it. A 1:15 ratio produces a more concentrated, heavier cup. A 1:17 ratio produces something lighter and more delicate. Most filter coffee works well somewhere between 1:15 and 1:17. The Studio defaults work around 15g, which is a sensible starting dose for the Omni Dripper and produces a single cup of roughly 200 to 250ml depending on your ratio.

Ratio is best left stable while you're adjusting grind size. Once grind is dialled in, you can shift ratio to adjust strength and body.

Water Temperature

Temperature affects how aggressively the water extracts from the coffee. Higher temperatures extract faster and more fully. For lighter roasts, temperatures between 92°C and 95°C help draw out sweetness and clarity. For darker roasts, 88°C to 92°C is usually more forgiving. If you're getting harshness from a dark roast even at a coarse grind, dropping temperature by two or three degrees is often the fix.

The Studio's instant heating is accurate and consistent, so temperature adjustments translate reliably across brews.

How to Gauge Your Coffee and Adjust

This is the practical heart of dialling in any coffee. Rather than chasing numbers, you're tasting the cup and identifying what needs to change. The flavour tells you whether you're over- or under-extracting, which points you directly to the right adjustment.

If the coffee tastes bitter, harsh, or drying: the coffee is likely over-extracting. Go coarser by three to five grind settings, or lower the water temperature by 2 to 3°C. Bitter and astringent are the clearest signs of over-extraction.

If the coffee tastes sour, sharp, or thin: the coffee is likely under-extracting. Go finer by three to five grind settings, or raise the water temperature slightly. Sour and sharp, particularly in the finish, point to under-extraction.

If the coffee tastes flat, weak, or lacks sweetness: this can mean under-extraction, but it can also mean the ratio is too high. Try a smaller ratio (1:15 instead of 1:16) and see if the cup gains more body and sweetness before adjusting grind.

If the coffee tastes good but you want more clarity: try the spiral or circular pour pattern instead of a centred pour, as these encourage more even extraction across the coffee bed and can reduce muddiness in the cup.

Make one change per brew. If you adjust grind size and temperature at the same time, you won't know which change produced the result.

The Secondary Variables: RPM and Pour Pattern

Once grind size, temperature, and ratio feel right, RPM and pour pattern give you a finer level of control over the character of the cup rather than extraction level itself.

Grinder RPM

The xBloom Studio grinder runs between 60 and 120 RPM in increments of 10. RPM affects how the burrs generate heat during grinding and how the particle distribution spreads.

At lower RPM (60 to 80), the grinder runs cooler and tends to produce a slightly wider range of particle sizes, which can add texture, body, and complexity to the cup. At higher RPM (100 to 120), the grind is cleaner and the cup tends toward more clarity and sweetness. The difference is subtle, and grind size will always have a greater impact than RPM alone, but once your recipe is otherwise dialled in, RPM is a worthwhile variable to experiment with.

Starting at 90 RPM is a sensible middle ground for most filter coffees. If you find your cup lacks sweetness and feels a little flat at an otherwise dialled-in grind, try moving to 100 or 110. If you want more texture and mouthfeel, try 70 or 80.

Pour Pattern

The Studio offers three pour patterns: centred, spiral, and circular.

A centred pour concentrates water in the middle of the coffee bed. This promotes a more immersive, slower extraction in the centre and can produce a heavier, more textured cup. It works well for denser, lighter roasted coffees that need encouragement to extract fully.

A spiral pour moves from the centre outward, covering more of the bed and encouraging even saturation. This is a versatile option that works well for most coffees and is a good default.

A circular pour runs along the outer edge of the bed, which is useful for flat-bottom drippers like the Omni Dripper as it avoids channelling through the centre. If you're finding uneven extraction or a muddy or hollow-tasting cup, switching to circular can help even things out.

Most Copilot brewers use the spiral pattern as their default and only switch when something specific in the cup points to a bed saturation issue.

Structuring Your Pours

The number of pours and the volume of each one determines how much agitation the coffee receives during brewing and how the extraction progresses through the brew. More pours with smaller volumes create more agitation and tend to produce more even extraction. Fewer pours with larger volumes are simpler and can produce a slightly heavier, more textured cup.

The bloom is always the first pour. Its purpose is to saturate the grounds and allow CO₂ to degas before the main extraction begins. Fresh coffee produces more gas, so a 30 to 45 second bloom rest is important. The bloom volume is typically two to three times the dose weight, so around 30 to 45ml for a 15g dose.

A three-pour recipe (bloom, second pour, third pour) is a practical structure that covers most coffees well and is easy to adjust. A four or five-pour recipe gives you more control over agitation and can improve evenness on denser lighter roasts, but adds complexity. Start with three pours and add more only if the cup consistently shows signs of uneven extraction.

Saving and Sharing Your Recipes

Once you've dialled in a recipe you're happy with, save it in the app. The xBloom Studio allows you to store up to three recipes directly on the machine itself, accessible via the A, B, and C preset modes. This means your favourite recipe for a particular coffee is available with a single button press, no phone required.

The xBloom app also allows you to share recipes with other Studio users. If you're happy with a recipe and want to share it, it can be sent as a link or an NFC-compatible virtual card. This is useful for matching a recipe to a specific coffee if you want to share that experience with someone else.

Dialling-in on The xBloom Studio

The most common mistake when starting with Copilot mode is adjusting too many variables at once. The xBloom Studio gives you enough control to change everything on every brew and it's tempting to keep tweaking. The result is usually that you lose track of what caused what and end up confused about where to go next.

A more effective approach is to fix every variable except one, brew, taste, and decide whether to move in the same direction again or try the opposite. Grind size first. Then temperature if needed. Then ratio for strength. Then RPM and pour pattern once the cup is otherwise where you want it.

The Omni Dripper is forgiving compared to something like a V60, which means reasonable recipes tend to produce drinkable results even when they're not perfectly dialled in. That makes Copilot mode a good environment for learning, because you're rarely far from a good cup, you're just working toward a great one.
