Getting Acquainted
Become familiar with the rapid cold brewer parts (Fig. A) and read the instructions carefully. The cold brewer comes fully assembled.
Before first use, disassemble and wash the parts using the following instructions:
1. Grasp the glass carafe with one
hand and the plunger knob with
the other (Fig. C). Pull up slowly
and firmly until the plunger and
stirring cup are completely out of
the carafe.
2. To remove the stirring cup from
the plunger, grasp the plunger
lid with one hand and raise it up
to the plunger knob. Place the
thumb of your other hand on
either one of the two tabs and
wrap your fingers around the
bottom of the cup (Fig. D). Push
the tab with your thumb. The cup
will slide off the filter.
3. Wash the carafe, plunger, and
stirring cup in warm, soapy water.
Rinse and dry thoroughly. The
carafe, plunger, and stirring cup
are dishwasher safe (top rack).
Do not remove the gaskets if
washing in the dishwasher.
CAUTION! To prevent electrical shock and damage to the coffee maker, do not immerse the base in
water or other liquid or allow the plug receptacle to get wet.
How to Use
1. Place the cold brewer on a dry, level surface. Make sure the control dial is in the OFF ( ) position
(Fig. B). If not, turn the dial counterclockwise until it stops. Insert the stirring cup into the carafe
and push down until it rests on the bottom of the carafe (Fig. E, page 3).
IMPORTANT: The brewer’s stirring mechanism will not work if the cup is not in this position.
2. Set the carafe on the base. Pour cold tap water or room temperature bottled water into the carafe to
the fill line (approximately 26 ounces). NOTE: If using refrigerated water, you will need to double
the brewing time.
CAUTION! If water is above the fill line, it may flow over the carafe during the stirring process.
3. Connect the power cord to the base (Fig. B) and then to a standard 120VAC wall outlet.
4. Turn the control dial until the line is just past the halfway mark between the OFF ( ) and
HIGH SPEED ( ) positions (Fig. F, page 3). Wait for the “tornado” to form. Then gradually
turn the dial until the tip of the “tornado” extends down to the post head of the stirring cup
(Fig. G, page 3). NOTE: Turning the dial too rapidly may cause spinning to stop. If this occurs,
turn the control dial off. Then slowly turn the dial back on until the line is just past the halfway
point (Fig. F).
5. Gradually (over about 30 seconds) add ⅔ cup medium grind coffee to the water. Medium grind
coffee is the standard grind for commercially available ground coffee.
6. After all coffee has been added, allow rapid brewer to stir for the amount of time needed to
produce the desired strength:
• 10 minutes for a flavorful lighter brew (equivalent to 12 hours of conventional cold brewing).
• 20 minutes for a flavorful full-strength brew (equivalent to 16 hours of conventional cold
brewing).
• 30 minutes for a flavorful ultra-strong brew (equivalent to 24 hours of conventional cold
brewing).

During the first 3 to 4 minutes, while the tornado is incorporating the coffee into the water, dry
coffee will remain on the surface of the water. This is normal.
NOTE: The rapid cold brewer can run indefinitely without damage to the unit.
7. If desired, the spinning speed can be increased after a few minutes by turning the control dial
clockwise. Increased speed may aid in the removal of grounds from the side of the carafe.
8. After stirring time is complete, turn the control dial off. Unplug the cord from the electrical
outlet and then from the base. Allow the coffee to rest at least 5 minutes.
IMPORTANT: Resting allows the grounds to settle, making the plunging/filtering process in
step 9 easier and more effective.
NOTE: After 5 minutes have elapsed, there will still be grounds visible on the top surface of
the coffee. This is normal.
9. While the carafe is still on the base, grasp the plunger knob and lid. Insert the plunger into
the carafe, making sure the filter is level (Fig. H). With straight downward pressure, press the
plunger knob slowly and evenly until the filter contacts the stirring cup (Fig. I). This should
take about 15 seconds.
IMPORTANT: If you plunge too fast, one or both of the following will occur:
• You will feel an increase in resistance.
• Numerous small air bubbles will begin to escape past the plunger gasket.
DO NOT CONTINUE TO PRESS. Instead, pull the plunger up slightly—about ⁄th of an
inch (2mm) is enough. Pause for a second. Then resume pressing again, evenly and slowly.
NOTE: You may notice some coffee collecting under the stirring cup. This is normal.
10. Pour coffee from the carafe, making sure to hold the plunger knob and lid in position on top of the carafe.
Glass Carafe Care
1. Do not use the carafe if it is cracked or chipped.
2. Avoid sharp blows, scratches, and rough handling, as these can damage the glass.
3. Do not use steel wool cleaning pads or abrasive powders to clean the carafe, as they may scratch the glass.
4. Avoid exposing the carafe to extreme changes in temperature; for example, adding hot water to a carafe that is cold could cause
the glass to break.
Cleaning
1. Unplug the power cord from the electrical outlet and then from the cold brewer base.
2. Pour any remaining coffee out of the carafe.

3. Place the carafe in a sink or on a flat surface next to a sink. Place a paper towel in the sink. Grasp
the carafe handle with one hand. With the other hand, apply slight downward pressure on the
plunger until the clip on the end of the plunger engages with the post head on the stirring cup. You
will hear a “click” when the clip engages the post head.
NOTE: If you do not hear the “click,” you will need to press more firmly to engage the post head.
4. Slowly raise the stirring cup (Fig. C, page 2) by pulling up on the plunger knob until the cup
touches the lid. Remove the plunger and cup from the carafe.
5. Slide the cup off the plunger (Fig. D, page 2). Empty the contents of the stirring cup onto the paper
towel, wrap it up, and discard.
6. Remove the gasket from the coffee filter. Wash the gasket, carafe, plunger, and stirring cup in warm, soapy water. Rinse and dry
thoroughly. The carafe, plunger, and stirring cup are dishwasher safe (top rack). Do not remove gaskets if washing in the dish-
washer.
7. Wipe the outside surface of the base with a damp cloth and dry.
CAUTION! To prevent electrical shock and damage to the coffee maker, do not immerse the base in water or other liquid or allow
the plug receptacle to get wet. If you notice any moisture, dry thoroughly before use.
8. Periodically remove the gasket from the stirring cup to remove any remaining coffee and grounds. Wash in warm, soapy water.
Reinstall the gasket without the holes on the plunger (Fig. A, page 2) by stretching it over the filter so that it fits in the groove.
Stretch the gasket with the holes (Fig. J) onto the stirring cup and place it in the groove on the top of the cup.
Questions and Answers
What temperature should the water be?
Cold tap water or room temperature water is recommended. If using refrigerated water, double the brewing time.
When I turned the control dial, nothing happened. What is wrong?
The stirring cup is not positioned correctly. When inserting it into the carafe, be sure to push it down until the bottom of the cup is resting
flat on the bottom of the carafe (Fig. E, page 3).
What type of ground coffee should I use in the rapid cold brewer?
Medium grind coffee is the standard grind for commercially available ground coffee and the type recommended for use in the rapid
cold brewer.
The stirring stopped when I turned the dial to high. What am I doing wrong?
The ideal stirring speed for cold brew occurs when the tip of the “tornado” extends down to the post head of the stirring cup. Avoid
turning the control dial beyond this point. If the dial is turned to the HIGH SPEED setting ( ), the rotation may stop. If this occurs,
turn the control dial off. Then slowly turn the dial back on until the line is just past the halfway point (Fig. F, page 3).
I noticed some sediment at the bottom of the glass. Is that normal?
Coffee prepared in the rapid cold brewer will have some sediment. It is common and contributes to the full-bodied avor of the result-
ing brew. If desired, the cold brew coffee may be poured through a coffee lter to remove the sediment.
I feel resistance when I press the plunger. Why?
If you notice increased resistance, it is an indication that the filter is obstructed. If this should happen, DO NOT CONTINUE TO
PRESS. Instead, pull the plunger up slightly—about ⁄th of an inch (2mm). Pause. Then resume pressing, slowly and evenly (Fig. H,
page 3).
Can I keep leftover brew for later use?
Yes. Store remaining cold brew coffee in the refrigerator.
Occasionally, I hear a vibrating sound. Is that a concern?
No. It is due to the position of the carafe in the base and is not an issue. Slowly move the carafe from one side of the base to the other
until you no longer hear the sound.
