Just got my hands on the new Aeropress GO.
I am very impressed that some seemingly minor changes can have such a positive result on the overall feel and experience of using the GO.
While the capacity is down from 300 ml on the larger Aeropress to 240 ml on the GO, any loss of capacity can be compensated for by use of higher brew ratios for later dilution.
This is the first opportunity I have had to use an Aeropress with the new silicone plunger seal. The plunger seal was changed to a silicone composition in September 2018. While it is early days yet this new seal seems a definite improvement on the old rubber seal. It is much smoother in operation and it doesn't look as though it will absorb oils and require massaging to maintain a seal like the old ones did. Another nice little touch, that demonstrates the thought put into design of the GO, is the measuring scoop provided. The previous scoop had a rounded base which meant that a loaded scoop was unstable if put down. The new elongated scoop has a small flat section on its base which means it is very stable when put down.
The concept of the travel mug to contain all of the GO parts is good but I have found the result to be a little bulky for my circumstances and probably won't use it. Those that use the plunger piston to house a grinder will find that the grinder will project more from the plunger piston but it is still a compact unit. This has given me the opportunity to resurrect my Precision Hand Grinder, which had unrepairable damage to the catch cup threads after it was dropped. With the threaded section removed the PHG disappears in the plunger. A catch cup solution is still needed. Anyone know where I can get a dosing cup type container with a 45mm ID?
A few dimension comparisons between the GO and the full size Aeropress.
Top of plunger (where hand pushes down) 71 mm diameter vs 83.5 mm
Cup mounting flange 87 wide mm vs 97 mm
Overall collapsed length 114 mm vs 133 mm
The GO filter holder has a new circular pattern for the outlet holes but previously available accessory metal filters still work. The holes stay the same 1/16" approx 1.6 mm diameter but the number decreases from 97 in the larger Aeropress to 74 in the GO. On my calculations this means the total outlet area goes down from approx 192  mm to approx 147  mm, or a 23% reduction. Interestingly, the GO filter basket base is thicker. Perhaps compensation for increased pressure resulting from reduced flow?
The GO is clearly marked in several places "Made in USA" (this is not apparent on my previous Aeropresses) and it is interesting that in addition to USA patents being taken out there are also 2 patents registered in China. Incidentally, I recently saw a photo on Instagram of a clear walled "Aeropress" (not a Delter) being used. This is the first time I have noticed what seemed to be an Aeropress knock-off.
Bottom line? I bought the GO for travel use but I like the feel so much that I am also using it as my regular Aeropress. For those quite happy with their current Aeropress I would recommend getting a new silicon plunger seal. However, you would need to emphasise when ordering that you want the new silicon seal, to avoid being given any old-stock rubber seals.
Totally agree that the new seal is better. I have a slightly older AP, but put a new seal on it a year or so ago and itís much nicer. Needs a few uses and washes to lose that static that is common with silicone rubbers, but after that itís excellent.
It sounds like the GO has some nice touches and will suit people that are regularly using it while traveling or on the go.
PS. That clear AP you saw may have been a V1 as they were originally clear when first released.
I think eBay is full of fakes. Very easy to spot, and you get a choice of clear or smoke
Awesome review, thanks for posting!
I also had NO idea a new seal was released... will have to get one for my old school AP! The rubber is struggling a bit
Otago thanks for letting us know about the new version. It sounds like it might be better for travelling, or making coffee for one. I take my regular aeropress camping, and I can tell you it's a hassle with the rounded scoop, so I'm really glad they have changed that. Grinding enough beans for two is really hard work, and then when the rubber plunger won't budge, it feels like the last straw. So I am glad they have changed it to silicone. I hope I can get a silicone part for mine.
After recent use of the GO travel cup I thought I should add how impressed I was with its heat retention performance. On first sight you would expect, with its fluted external design and relatively thin walls, that it would lose heat quickly. However, I thought it kept the contents hot for an acceptable time.
Also, after a query from justacuppa on the Precision Hand Grinder, I now realise that the GO plunger internal diameter is 51.5 mm compared with 50 mm on the original Aeropress. This brings some other hand grinders into contention for use with the GO.
