AeroPress Go Travel Coffee Press
Some of the early AeroPress Go chambers have a problem. The filter cap will not engage when you screw it onto the chamber. Please see the two photos, one with the filter cap not engaged and one with the filter cap engaged. If you have an AeroPress Go that the filter cap and the chamber will not engage, send your request along with your mailing address to [email protected] and we will send you a new chamber. We apologize.
The AeroPress Go can brew with one pressing:
– Up to three servings of espresso style concentrate. You can enjoy a serving as espresso or add water or milk to create an 8 oz. coffee or latte. The preceding can be done with hot or room temperature water and the drinks can then be enjoyed hot or cold. It should be noted that the way to fill the large AeroPress Go mug is to brew two servings and then add water or milk to fill the mug with coffee or latte.
– If you prefer to brew your coffee by pushing all the water through the grounds, you can brew one 8 oz. serving of coffee or cold brew.Share
Up to 20 Micro-filters.Share
When fully packed up in the mug with the lid on top, the AeroPress, its accessories, and the 20 paper filters that fit into the travel filter holder weigh 11.4 oz. (323 g) altogether.Share
The AeroPress, mug, and accessories are made of food-safe polypropylene that is free of BPA and phthalates. The lid and plunger seal are both made of silicone and the filters are made of paper.Share
The mug holds 15 oz. (444 ml) or almost two 8 oz. (237 ml) servings of American style coffee or cold brew coffee.Share
The AeroPress Go comes with 350 Micro-filters.Share
The AeroPress Go is manufactured in the United States.Share
Yes, all AeroPress Micro-filters are compatible with both the AeroPress Go and the original AeroPress coffee maker.Share
Brewing with an AeroPress
A good grinder will grind coffee into particles of uniform size. Very fine particles block the flow of water and make it difficult to press. The same blocking occurs if your grinder is dull and produces particles of varying size because the fine particles block the spaces between the larger particles. We recommend using a burr grinder instead of a blade grinder.Share
Use fine drip or espresso grind. Espresso grind takes longer to press and requires skill and patience for multiple scoops but makes a richer brew more quickly due to more particle surface area. You can use preground drip coffee from the grocery store but you may want to use slightly more coffee or let it steep for a little more time to reach the same strength it would reach using a finer grind.Share
A level scoop holds 11.5 grams of coffee or about 2.5 tablespoons. A heaping (rounded) scoop of coffee holds 14 grams or 3 tablespoons.Share
We don’t currently make a larger AeroPress. But if you do two or three 3-scoop pressings into an 8 or 12 cup carafe and then top off the pot with hot water, you will have enough American style coffee to serve a small gathering in less time than it takes to brew a carafe of drip coffee.Share
All of our tasters agreed that coffee brewed at these temperatures tasted the best. These temperatures deliver smooth, rich brews without the bitterness and acidity that come with using hotter water. One of the advantages of the AeroPress is the user controls all the brewing process variables including the temperature of the water used. We recommend brewing with water of different temperatures to determine one's personal preference.Share
Look down into the chamber from above. The numbers on the outside are visible through the material particularly if looking down against a light background.
Ground coffee floating around in the chamber can make it difficult to judge the water level. Try pouring in half of the water, stirring to wet all the grounds, and then pouring up to the desired level.Share
It is normal for a minor amount of liquid (about 5%) to drip through prior to stirring and pressing. If a lot of liquid runs through prematurely, remember to shake to level the grounds and pour the hot water slowly. If an excess amount still runs through prematurely, you need to use a finer grind of coffee.Share
- You may need to use a better or sharper grinder. A good, sharp grinder (ideally a good burr grinder) grinds coffee into particles that are all the same size. A cheap or dull grinder produces a wide variety of particle sizes and the very small dust-like particles at the fine end of the particle size distribution block the flow around the larger particles, turning the layer of coffee particles into a barrier that blocks your pressing.
- Press gently, there is no rush. Pressing hard actually compacts the coffee particles into a barrier, making it harder to press. You can try pressing down half an inch, then hold the plunger there and let the air pressure in the chamber do the pressing for you. Then after 5 or so seconds of waiting, press another half inch down and repeat until finished pressing.
- If the above two points don’t work, use a coarser grind until you get to where a minor amount drips through prior to pressing and slow, gentle pressing takes 20 to 40 seconds.
Many people say that espresso must be made with 9 bars of pressure. If you use this definition then no, the AeroPress does not make espresso. But if you define espresso by the taste of the drink in the cup, certainly many people think the AeroPress can brew espresso. Since AeroPress brewed coffee can be made into lattes, cappuccinos, and other espresso based drinks, we feel it is important to use the term "espresso" when describing what the AeroPress brews so potential customers will understand how AeroPress brew can be enjoyed.Share
Other AeroPress Brewing Methods
The instructions provided with the AeroPress and also available to download from this website describe a starting point from which users can deviate if they wish. The taste of brewed coffee is affected by all the variables in the brewing process. When using an AeroPress the user selects the water temperature, the brew time, the coffee to water ratio, etc. The AeroPress enables the user to control all the brewing process variables and thereby brew a particular coffee with a desired brewing recipe. Taste is personal. There is no right answer to the question of how to brew a particular coffee and there is certainly no right answer for how to brew all coffees. With that said, we think the method described in the instructions is a good one for most coffees.Share
People who use the inverted method do so to prevent any premature drip-through of their coffee and to give them complete control over usually longer brew times. If you want to use a long brew time, we recommend using the normal method but insert the seal on the end of the plunger a half inch or so into the top of the chamber to stop drip-through while waiting for your longer brew time. The seal stops drip-through just like putting your finger on the top of a straw stops dripping out of the bottom of a straw. We think shorter brew times brew better tasting coffee but taste is certainly personal and people should brew their coffee the way it tastes best to them. Be advised that using the inverted method may increase the risk of spilling hot water and the risks associated therewith.Share
Yes, using the inverted method. Insert the plunger an inch or so into the chamber and then set the AeroPress on a counter with the plunger down. Put the tea into the chamber, pour hot water into the chamber, and let it steep. When ready, put a filter into the filter cap, screw the cap onto the chamber, carefully invert it onto your mug, and press. Be advised that using the inverted method may increase the risk of spilling hot water and the risks associated therewith.Share
No. The bleaching process used by filter paper manufacturers until the late 1980s used chlorine gas and the chlorine gas bleaching process created dioxin as a byproduct. In the late 1980s the filter paper mills switched to using what is called the non-elemental chlorine bleaching process (they use a chlorine compound, not chlorine gas) to eliminate producing dioxin as a byproduct.Share
Every AeroPress coffee maker comes with 350 AeroPress paper filters. We do not manufacture or sell filters for use in the AeroPress made of other materials such as metal. We were originally planning to include a metal filter with each AeroPress but when we conducted blind taste tests comparing paper filtered coffee with metal filtered coffee, the paper filtered coffee always won. We also learned using a paper filter is healthier because it removes diterpenes from coffee and diterpenes are potent agents that raise your bad cholesterol. Metal filters do not remove diterpenes. AeroPress paper filters are 100% compostable along with the coffee grounds and they retail for less than a penny and a half each so they are gentle on the environment and your wallet. That said, while we think that paper filters brew better tasting coffee, taste is certainly personal so people should brew their coffee the way it tastes best to them.
There are many companies that manufacture filters designed for use in the AeroPress coffee maker made of other materials, particularly metal. We do not object to these other companies selling their filters but none of them can legally use our AeroPress trademark. It is important to note that the AeroPress limited one year warranty does not cover operation with a filter made by another company or damage to the AeroPress caused by use of such a filter.Share
No. We did a market test and bleached filters were far more popular than unbleached filters with our customers. The AeroPress filter is just a 2.5 inch (63.5mm) diameter circle of the same filter paper used in a cone filter. You can cut your own from unbleached cone filters.Share
AeroPress and Health
Cafestol and kahweol are diterpene molecules found in coffee. They are powerful agents that cause our bodies to increase the low density lipoproteins (LDL or "bad" cholesterol) in our blood. Cafestol and kahweol are removed from coffee by paper filters. Any coffee maker using a paper filter (such as the AeroPress coffee maker) removes virtually all of the cafestol and kahweol from the brew. We had this verified by an independent test lab for AeroPress brewed coffee.Share
AeroPress brewed coffee contains about one-fifth the acidity of drip brewed coffee and one-ninth the acidity of French press brewed coffee. Because of this it’s easier on your stomach.Share
Tests done by an independent researcher showed that the caffeine content of AeroPress brewed coffee is the same as comparable strength coffee brewed using other methods. People often find they enjoy their coffee stronger when it is brewed in an AeroPress because of the lack of bitterness, so that would result in more caffeine per cup.Share
AeroPress Design Questions
We stopped putting the water level marking numbers on the plunger because we were concerned that they encouraged the use of the plunger in microwave ovens and we just do not know what effect microwaves have on the life of the rubber seal.Share
The bottom circular rim of the chamber is firmly clamped down on the paper filter when you screw the filter cap onto the bottom of the chamber. Therefore all the coffee that you press down must go through the filter paper. There is a tiny amount of coffee that instead of going straight through the filter and into your mug goes sideways through the filter paper and emerges outside of the chamber in the filter cap. The side holes in the filter cap are there to enable this small amount of coffee to drip down into your mug. If those side holes were not there, some of this coffee would be pushed up and over the rim of the filter cap and then drip outside your mug.Share
The biggest mug you can press into with the AeroPress has a top inner diameter of 3 3/4 inches (95mm). The smallest mug you can press into with the AeroPress has a top inner diameter of 2 5/8 inches (67mm).Share
We removed the ridges because they were scratching the inside of the chamber and had no function. We initially put the ridges on the plunger because we thought they would provide needed additional strength. That was not the case and to our surprise they were a source of scratching of the inside of the chamber.Share
Use the AeroPress funnel to transfer the ground coffee from your coffee grinder bin to the AeroPress chamber. It was not an intended use but users have told us that the funnel fits on the bottom of the chamber and enables you to press into smaller mugs. If you do this, we advise you to make sure you use a sturdy mug and that you firmly hold the mug and AeroPress during pressing to avoid spilling.Share
Plunger with Seal: 5.26" tall, 3.28" diameter
Chamber: 4.75" tall, 4.22" diameter (at widest part of the hexagon)
Compressed Plunger + Chamber: 5.26" tall (height of the Plunger), 4.22" diameter (diameter of Chamber)Share
The original AeroPress and the Go have the same cylinder diameter but the flange that supports the AeroPress on your cup is smaller on the Go. The Go can sit on a cup with a maximum inside diameter of about 3.25” whereas the original AeroPress can sit on a cup with a maximum inside diameter as big as about 3.75”. The original AeroPress and the AeroPress Go will both press into a mug with a minimum opening diameter of 2.75”.Share
Cleaning an AeroPress
You can in the top shelf, but a simple rinse is sufficient because the plunger wipes the chamber. If your chamber ever gets sticky, wash it with vinegar. We recommend occasionally removing the seal from the end of the plunger for a good washing inside and out with warm water and dish soap.Share
The seal can be cleaned using hot water and dish soap. We advise you to occasionally remove the seal from the plunger and wash it inside and out with hot, soapy water to prevent the accumulation of coffee oils. Use a paper towel to provide a little abrasiveness.Share
Your seal has become compressed and is no longer big enough to tightly seal the chamber. Whenever the seal is inside the chamber, it is being held compressed. Eventually the compression forces prevail and the seal becomes too small. To maximize the life of your seal you need to minimize the time your seal is held compressed. This means eject the spent coffee immediately after every pressing and store the seal either pushed all the way through or removed from the chamber.
What can I do?
Buy a new seal: The seal can easily be replaced on the end of the plunger so one solution is to buy a new seal on our website. With care, a new seal should last at least three years.
For a quick fix: Joe Lindsay sent us his short-term fix: First place the rubber end of the plunger in some hot water for a couple minutes. Then press the rubber end of the plunger onto a flat surface such as a cutting board. While pressing roll the seal around on its edge so that you are pressing the edge out, widening the circumference of the seal.Share
Yes. The black seal is fitted onto the end of the plunger. There is no adhesive. To fit the seal back onto the end of the plunger, position the seal on the end of the plunger and then turn the seal while pressing it onto the plunger until it gets fully seated.Share
The weight of the AeroPress (including the AeroPress, the filter cap, the filter holder, the pack of 350 filters, the scoop, the stirrer, and the funnel) is 13 ounces. The weight of the zippered nylon tote bag alone is 0.5 ounces.
When camping, backpacking or traveling light, the parts of the AeroPress you would take along (the chamber, the plunger, the filter cap, and however many paper microfilters you thought you’d need) weigh 6.5 ounces. You would leave the AeroPress filter holder, scoop, funnel, and stirrer at home, and use whatever spoon you were already bringing on your hike as a scoop and stirrer.Share
Holding the AeroPress with the seal facing you, brace your fingers around the chamber flange and push both of your thumbs against the seal. This will push the plunger up through the chamber making it easier to pull the two pieces apart.Share
This is like removing a screw top lid stuck on a jar. You can try lubricating the filter cap with a little water or cooking oil to make it easier to turn. Or, you can buy a sheet of rubber like material that is intended to help you grip the lids of jars to make it easier to twist the lids – try using one of those. You also can try running hot water over the filter cap (not the chamber). The filter cap expanding with heat may make it easier to turn.Share
AeroPress brand products are warranted against defects in materials and workmanship for one year from the date of purchase from an authorized retailer. Authorized retailers are those listed on this website. If you think you purchased a defective AeroPress product that is under warranty, please contact us and report the problem. We will promptly be in touch.Share
Always eject the used coffee right after brewing and store your AeroPress with the silicone seal pushed all the way through the chamber. This keeps the seal free of compression for longer seal life.Share
The AeroPress is manufactured in the USA.Share
The seal is made of silicone. Silicones are rubber like materials that are primarily made of silicon and oxygen. They are frequently used in the manufacture of kitchen implements including those used for baking because of their non-toxicity and excellent durability including resistance to heat. Up until October of 2018 the AeroPress seal was made of a thermoplastic elastomer. Both the silicone and the thermoplastic elastomer are made in the USA and are FDA and EU approved for use in contact with food.Share
No. The AeroPress has always been free of phthalates and has been free of BPA since August of 2009.Share
In the summer of 2014 we switched to making the chamber and plunger out of polypropylene. This means that all of the AeroPress parts except the silicone seal are now made of polypropylene. We made the change because tests indicated the polypropylene is more durable. We regret the polypropylene is less transparent but feel the additional durability is more important. All materials used in the AeroPress are made in the USA and are FDA and EU approved for use in contact with food. Read more about the materials here.Share
