‘stretching’
of the milk – in other words, adding air to the milk. When done properly, the sound you
hear at this point resembles ‘sucking’. You continue this until the milk reaches an approximate
temperature of 100 degrees.
After your milk has reached this ‘body temperature’, submerge the tip of the steam arm approximately
one inch below the surface of the milk. This process continues to roll the milk over itself again and
again – breaking the large air bubbles into tiny air bubbles – resulting in a new, creamy and sweeter,
texture
of the milk. When your milk has reached approximately 155 degrees – turn the steam valve
off.
Helpful Tips and Information
•
When turning the steam valve off, always keep the tip under the surface of the milk for
approximately 3 seconds. If you pull it out too soon, you will destroy the nice velvety micro-
foam.
•
While texturizing the milk, if you lower the tip too far into the milk you create turbulence rather
than rolling. Turbulence will not make micro-foam.
•
If there are a few bubbles in the milk after you have finished, wait 5-10 seconds to allow all the
remaining bubbles to surface, then simply tap the edge of the pitcher on the counter and swirl
the milk slightly and they will disappear. This is often a good time to purge your steam arm
and wipe it down.
•
Be sure to keep your steamed milk moving/swirling until you are ready to pour since milk has a
natural tendency to separate.
Regular Maintenance
Backflushing is a vital maintenance procedure you must follow to help keep your machine running
flawlessly for years to come. There are two types of backflushing; one with plain water, and the
other with espresso machine cleaner.
Plain water backflushing
should be done
at least
once a week, however if you are so inclined,
feel free to backflush with plain water as often as you like. It won't harm the machine and keeps
the dispersion screen clean.
To backflush, you use the portafilter’s blank insert (the round stainless steel disk without holes).
To remove your single or double portafilter basket, use the blank portafilter insert. Turn it upside
down and use its edge to pry the basket out of one of your portafilters. (If you always make double
