Frequently Asked Questions
How many coffees can you get from a gas bulb?
Each bulb makes 8 single shots or 4 double shots espressos.
Where can I buy spare gas bulbs?
The gas bulbs for mypressi are similar to those used for whipping
cream dispensers. So, you can possibly find those bulbs in hospitality &
kitchenware shops and occasionally from supermarkets. Beware that bulbs
can vary in size depending on the brand and that some bulbs are too big
to fit in mypressi handle. According to our tests, the ISI brand bulbs fit in
mypressi handle. You can also
order mypressi bulbs online.
The water bowl is not easy to remove.
In rare cases, coffee particles may block the small hole in the middle of the rubber valve
inside the showerhead and prevent a rapid equalization of pressure. Give the TWIST sufficient
time to release all pressure (sometimes as much as 5-10 minutes or more)
and then thoroughly clean the showerhead and rubber valve.
The water bowl lid has become difficult to open or close.
Apply a small amount
of food safe lubrication to the gasket on top of the water bowl. Wipe
away any extra lube to keep the area clean.
An o-ring is not sealing
the way it used to.
Replace the o-ring using one of the spares included with the
TWIST.
Water leaks through the
water bowl when I fill it with hot water.
This is probably due to the rubber
disc having coffee grounds trapped underneath.
Time to do a deep clean. Here's how to clean the shower head:
Gently pry off the o-ring on the
underside or tap plastic part of the assembly against a hard surface
until the o-ring falls out. The metal piece should easily separate
from the assembly so you can clean around and under the rubber disc
with soap and water. Rinse well. Reassemble after cleaning.
The extraction seems fast and
results in weak coffee. The coffee sometimes even overflows from the top
of the bowl. What’s happening?
Usually this is caused by coffee that
is too coarse. The freshness of the coffee and the humidity in the air
can also effect the rate of flow. Here are some troubleshooting tips:-
- Use a finer grind of coffee. Make adjustments toward the finer settings
on your grinder. We recommend
using a high quality burr grinder.
Blade grinders cannot grind
sufficiently fine. They also heat up the coffee in the grinding process,
creating large variances in the flow rate of your espresso.
- If you are
having problems getting a fine enough grind, try using the coarse
basket. If you rub a fine espresso grind between your fingers it will
feel like flour mixed with a little salt.
The extraction seems too
slow, somewhat drippy and doesn’t provide a steady pour. It may even
taste salty.
This is a slow extraction and it may be caused by several
factors:
- You may have dosed in too much coffee.
- The grind setting may
be too fine requiring a coarser grind of coffee to allow water flow.
When I use pods to make a cup of espresso the water shoots through very fast and the espresso is blond and very watery. What am I doing wrong?
You may be using the standard basket and standard showerhead. It is important that you use both the pod basket and pod shower head in order to extract the coffee properly from a pod.
When I use pods the espresso still comes out watery
You may be pre-portioning too much water in the water bowl. Fill the water to the
lower fill mark in the bowl when using pods.
How do I know if there is sufficient gas left in the cartridge to make another shot of espresso?
You can make 4 double shots or 8 single shots of espresso from one cartridge.
If you have lost track, remove the water bowl and while holding the TWIST away from you, give the trigger a quick squeeze to see if there is any pressure in the system. Gas will come out of the small o-ring on top of the handle and may be followed by a small amount of water spray.
If you have pulled sufficient shots already, you will probably notice just a small amount of gas followed by the cartridge running out of pressure. If you get a good blast of gas coming from the small o-ring then you can probably make at least one more shot.
Why does water occasionally leak out near the trigger during use?
This is due to condensation and is normal. Just wipe off the water
and continue.
Sometimes the espresso is not very hot when I make a shot. What can I do to make it hotter?
There are a number of things you can do to get consistent and proper water temperatures:
- Pour hot water directly from your boiling kettle into the water bowl.
- Preheat the cup or shot glass before use, but don’t fill to the top or you risk burning your lips. You can also run some of that hot water through the basket and spouts to ensure all components are preheated, or make a “naked” shot with the spouts removed for even hotter results.
- Preheat the water bowl in a similar fashion, fill it with boiling kettle water and dump the water after 15-20 seconds. Repeat if required. Cooler shots can taste a little sour, so the more heat you bring in at the start, (ranging from 197-204F at the point of extraction) the better opportunity you have for great espresso.
