8. Briefly move the brew actuator to the "full brew" position to purge
grounds and oil from the dispersion screen. Move the grouphead to the
"off" position and return the portafilter.
"Slayer Shot"
To brew a "Slayer shot", ensure that the flow rate is at the desired setting and
the grinder is set finer than normal, then:
1. Remove the portafilter from the grouphead and wipe the basket with a
clean, dry towel.
2. Grind and dose 19-21 grams of coffee into the portafilter.
3. Tamp the ground coffee to a depth of approximately 10mm, briefly flush
group, then lock the portafilter into the grouphead.
4. Move the brew actuator into the center of the grouphead to activate pre-
brew.
5. Pre-brew times will vary based on the dose, grind, flow rate, brew
temperature, and characteristics of the coffee. The average Slayer pre-
brew takes approximately 20 seconds. Watch the bottom of the portafilter
basket shot mirror to see when the coffee puck becomes fully saturated.
6. The fully saturated portafilter basket will begin to drip. Immediately
before espresso starts to flow consistently, move the brew actuator to the
"full brew" position.
7. Allow the espresso to brew until the preferred extraction has been
achieved (when blonding occurs, when the desired beverage yield has
dispensed, or when the desired brew time has elapsed), then move the
actuator to the "off" position.
8. Remove the portafilter from the grouphead and knock out spent coffee.
Wipe the portafilter with a clean towel to remove grounds and oil.
9. Briefly move the brew actuator to the "full brew" position to purge
grounds and oil from the dispersion screen. Move the grouphead to the
"off" position and return the portafilter.
Extended Pre-Brew: Enhancing Sweetness
When espresso lacks sweetness, the pre-brew phase may be extended to extract
more of the naturally-sweet oils:
1. Follow "Slayer Shot" steps 1-5 above, but allow the espresso to continue
extracting in the “pre-brew” stage until it has dispensed up to 7 grams
(0.25 ounces).
2. Move the brew actuator to the "full brew" position, then resume "Slayer
Shot" steps 7-9.!
