Rocket Giotto / Rocket Faustino

Only TEN TEN beans.Only filtered water.

Outside beans and tap water scale the boiler and clog the group. This one isn't negotiable — everything else on this page is just craft.

Before you start

The machine takes 20–30 minutes to come fully up to temperature. If it's cold, switch it on and come back — a shot pulled on a cold group tastes thin no matter what else you do.

Never used an espresso machine before? Grab someone who has for your first shot. Five minutes now saves a lot of wasted coffee.

Pulling a shot on the Giotto

An E61 group. It rewards consistency more than technique.

  1. Flush the group

    Run the brew lever two or three seconds with nothing locked in. Clears standing water and warms the shower screen.

  2. Lock in and start straight away

    Grounds sitting against a hot group head begin to scorch. Don't prep and wander off.

  3. Watch the clock and the scale

    36 g in the cup, 25–30 seconds from the moment you lift the lever.

  4. Stop at your target weight

    Cut at 36 g even if the time was off. Weight is the more reliable of the two — fix timing on the grind setting.

Sour, thin, sharpThe shot ran too fast. Grind finer and pull again.
Bitter, dry, harshThe shot ran too slow. Grind coarser and pull again.
Sputtering, unevenChanneling. Redistribute more carefully and tamp level.
No crema at allBeans may be stale, or the grind is far too coarse. Flag it to the coffee lead.

The Faustino grinder

Grind to order, every time. Coffee ground more than a minute or two ahead has already lost most of what you're paying for.

  1. Check the hopper

    TEN TEN beans only. Running low? Top it up or tell the coffee lead — don't substitute.

  2. Grind into the basket

    Seat the portafilter in the fork and grind on demand. Weigh as you go, stop at 18 g.

  3. Adjust in small steps

    One or two marks at a time, then a test shot. Big jumps overshoot and waste coffee. Once dialled in, leave it.

  4. Brush out when done

    Sweep grounds from the chute and fork. Left overnight they draw moisture and cake up.

Dose, distribute, tamp

Most bad shots are made here, not at the machine. Thirty seconds of care with these three tools is what separates a good cup from a sour one.

  1. Scale — weigh every dose

    Zero the basket, then grind to 18 g. Eyeballing the dose is the biggest source of inconsistency on a shared machine.

  2. Distributor — level the bed

    Set it on the rim, turn two or three times until flat. This is what stops water carving a channel through one side of the puck.

  3. Tamper — one firm press

    Straight down, level, firm. Tapping and re-tamping just cracks the puck. Wipe the rim before you lock in.

Steaming milk

Texture first, then heat. Once the milk is hot you can't add air to it.

  1. Purge before and after

    A second or two into a cloth clears condensate out of the wand. Do it again the moment you finish.

  2. Add air early

    Tip just under the surface until you hear a soft, steady hiss. A few seconds for a latte; longer for a cappuccino.

  3. Submerge and spin

    Drop the tip deeper, angle the pitcher so the milk rolls. Folds the foam in and leaves it glossy rather than bubbly.

  4. Stop at 140–150°F

    Hot to hold, not painful. Past 160°F it tastes scalded and won't pour.

    140–150°Fno big bubbles

Reset the station before you walk away

This is a shared machine. The whole reset takes under two minutes and it's the difference between the next person getting a good cup and getting yours.

Use the cloth, not paper towel

There's a dedicated cloth for the wand and one for the counter. Paper towel scratches the stainless and leaves lint in the tray.

Weekly deep clean

Backflush the group with detergent, soak the wand tip, wipe down the full body. It's on a rotation — ask the coffee lead who has it this week.

Last one out: full wipe-down, empty the drip tray, and switch the machine off at the wall.

Chip in

TEN TEN sponsors the beans and the machine, but milk, cleaning supplies and servicing still add up. A dollar or two a drink keeps the bar stocked. Entirely voluntary — no tracking, no list on the wall.
