From a cold machine to a perfect pull. Today: setup & first shot. Tomorrow: dial-in.

Step 1 · Today

Your First Pull, End to End

~25 minutes from open-box to crema in the cup. The first shot will probably not be perfect — that's normal and we'll dial it in later. The goal today is a clean ritual you can repeat tomorrow.

Before you flip a switch ~3 min

  • Wash all removable parts with warm water + mild dish soap: drip tray, drip-tray cover, water tank, both baskets, portafilter. Rinse thoroughly. Dry.
  • Fill the tank with cool, filtered water (RO or carbon-filtered tap). The Series 1 tank holds 2 L (67.6 fl oz). Don't use distilled — espresso boilers need some minerals to brew right and to keep heater elements happy.
  • Re-seat the tank fully into the back; you should feel it click home.
  • Plug the grinder in too. Lock the bean hopper onto the Virtuoso+ (twist-on).

First boot & group-flush ~5 min

  • Press the dial — or any of the piano keys — to wake the machine. Walk through any first-boot prompts (language, units, time).
  • Warmup is ~2 min from cold thanks to the Boosted Boiler (boiler + flow-through heater + group-head heater all firing). The screen tells you when it's ready.
  • While it warms: open the Fellow app on your phone and pair (Bluetooth, then handoff to Wi-Fi). Accept any firmware update. The app isn't required to brew, but it's where custom profiles live.
  • When ready, do 2–3 manual flushes of just water through the empty group head (no portafilter, or empty portafilter — your choice). This rinses any factory residue and brings the group up to brew temperature. Empty the drip tray.

Set up the Virtuoso+ ~3 min

  • Add ~30 g of beans to the hopper — a little more than your dose so the burrs aren't ground-starved. Use fresh whole beans, ideally roasted 5–21 days ago. Brand-new beans are gassy and channel; old beans taste flat.
  • Set grind to 8 on the dial (the Virtuoso+ has 40 settings — espresso lives roughly 4–12, and 8 is a sane mid-espresso starting point).
  • Skip the timer. We'll use pulse mode instead: hold the front pulse button to grind on demand, release to stop. More accurate when you're weighing the dose.

Dose & distribute ~3 min

  • Snap the 18 g single-walled basket into your bottomless 58 mm portafilter. Use the single-wall, not the pressurized double-wall — the naked basket shows every channel and is how you actually learn.
  • Place the portafilter on a 0.1 g scale, tare. Hold it under the grinder spout in the portaholder.
  • Pulse-grind until the basket reads 18.0 g ± 0.1 g. If you overshoot, that's fine — pinch the excess out.
  • WDT (Weiss Distribution Technique): poke through the grounds in a circular pattern with a thin needle (an unfolded paperclip works) for ~10 seconds. This breaks up clumps and prevents channeling. Tap the side of the basket once to settle.
4

Tamp ~30 sec

  • 58 mm tamper. Dry hand on the basket bottom, fingers off the rim.
  • Press straight down with about 30 lb / 13 kg of force until the tamper bottoms out — the basket has a shoulder you'll feel. Force matters less than level — the puck has to be flat or water will channel through the low side.
  • Polish: a small twist + light press to glaze the surface. The puck should look flat, edge-to-edge, no light gap at the rim.
5

Pull the shot ~1 min

  • Flush the group for ~2 seconds with no portafilter to clear standing water and stabilize temperature.
  • Lock the portafilter in firmly — handle ends up around 6 o'clock (gasket-dependent).
  • Place a pre-warmed cup on the drip tray, on the scale, tared with the cup.
  • Pick the simplest preloaded profile — usually called Classic Espresso or Standard Double: short pre-infusion → ramp to ~9 bar → hold → ramp down. Don't build a custom profile yet.
  • Press start. The screen shows the phase, the timer, and the pressure gauge live. Watch the gauge climb during pre-infusion, plateau through the main pull, taper at the end.
  • Stop the shot at 36 g out (1:2 ratio from your 18 g in). Press stop on the dial — the machine doesn't stop on weight automatically on a manual profile.
6

Clean as you go ~1 min

  • Knock the spent puck into a knock box (or trash, with a tap of a wooden spoon). The puck should hold its shape — a sloppy puck means too little dose or too coarse a grind.
  • Rinse the portafilter and basket. Wipe the group gasket with a dry microfiber. Do NOT use soap on the group.
  • Once a week (or every ~30 shots): backflush with the included blank disk + a pinch of espresso machine cleaner. Series 1 has a "Clean" routine in the menu — let it run.
  • Empty the drip tray when the float pops up, or daily, whichever first.
Step 1.5 · Right after

Reading Your First Shot

Before you taste, look. Then taste twice — first sip hot, second sip after 30 seconds of cooling. The cool sip is the honest review.

Color & Crema

Deep brown · 2–4 mm tan crema

Tiger striping (light/dark streaks) is gorgeous. White streaks = channeling. Crema should hold for 30+ seconds before breaking.

If pale & thin: grind finer · stale beans · puck under-tamped.

Time

27–35 seconds total

Includes pre-infusion. Screen shows the live timer. A few seconds either way is fine — the taste is what matters.

If < 25 s: grind too coarse. If > 40 s: grind too fine.

Yield

36 g out (1:2)

Stop the shot at the cup weight, not the timer. Standard double espresso ratio for a balanced cup.

Pulling lungo? Try 1:2.5 (45 g) for sweetness on lighter roasts.

Taste — sour

Under-extracted

Sharp, citrusy, lemony in a bad way. Water rushed through too quickly to pull out the sweet stuff.

Fix: grind finer (lower number) by 1 tick · or pull longer to 38–40 g.

Taste — bitter

Over-extracted

Ashy, harsh, drying on the tongue. Water sat too long pulling out the burnt flavors.

Fix: grind coarser (higher number) by 1 tick · or stop earlier at 32–34 g.

Taste — sweet & balanced

You nailed it ☕

Chocolate, caramel, nuts, fruit notes that match the bag's roaster card. No sour bite, no bitter finish.

Now: log the settings. We'll save this in Step 2.

Step 2 · Coming next

Dial-In

A logbook that learns your palate

Every pull becomes a row: bean (origin, roast date), grind setting, dose, yield, time, taste notes. Patterns emerge after ~20 shots. As your Virtuoso+ burrs season over the first ~500 g, the "right" grind for a bean drifts ~1–2 ticks coarser; the logbook catches that drift before your tongue does.

App-bridge

Fellow has not published a public API or BLE spec for the Series 1. The mobile app talks to the machine over Bluetooth/Wi-Fi for profile sync & shot analytics — a packet-capture + Python daemon could mirror those events. ~1–2 sessions of work, only worth it after the logbook proves out.

Right call: log shots manually for two weeks, then we decide if the bridge is worth chasing.

WE built this together — Max & Vivi

One coffee at a time. Step 1 is the ritual; Step 2 is the science. Both are how we tune.
