More info that might help you make a decision (bottom line up front: NDE Laboratories of Pleasanton California analyzed AeroPress concentrated brew and reported that no BPA (Bisphenol-A) was detected).
Beginning on August 1, 2009, Aerobie, Inc. switched to making the AeroPress coffee maker out of copolyester along with polypropylene and thermoplastic rubber. All three materials are BPA free. Coffee brewed in the earlier version tested to be free of BPA but with the new availability of copolyester, we were able to switch to using all BPA free materials and eliminated even a perception of risk. Since our inventory was at zero on August 1st, we also began shipping BPA free AeroPress coffee makers on August 1, 2009.
I emailed Aerobie a few days ago to ask if they were going to have any plans for a stainless steel or glass aeropress. This is what they had to say:
Thank you for your interest in our AeroPress coffee maker. We often get asked if we plan to make a glass or even a stainless steel version. Unfortunately glass is heavy, fragile, and expensive to manufacture with the required tolerances and stainless steel is heavy, opaque, and expensive. The plastic AeroPress is superior to what could be made of glass or stainless steel so we have no plans to make one of those materials.

I'm sure it'll just be a matter of time before someone else makes one in SS or glass. I sure hope so anyways.
I'm looking for more specific information. Does the plastic in the Aeropress contain bisphenol A (BPA)? This is the offending material linked to the development of heart disease and estrogenically-linked cancers. Problem: as Wikipedia (yeh, I know, but there's a citation) notes from the April 2008 *Scientific American*: "When such plastics are exposed to hot liquids, bisphenol A leaches out 55 times faster than it does under normal conditions, at up to 32 ng/hour" (from http://en.wikipedia.org/wiki/Bisphenol_A).
I went to the manufacturer's site and found nothing that would answer this simple question. But based on the product description of the plastic, this is a strong candidate for polycarbonate with BPA.
Simple question: Does the Aeropress's plastic contain BPA, or not? Assurance that this product is BPA-free will go a long way toward selling me on it.
I am kind of annoyed at everyone's antagonism to lexan water bottles, but you have to realize that no one really knows much about exposure levels to BPA, and brewing a cup of coffee is the perfect environment for leaching this stuff out (hot and oily).
I followed the link posted above, and a reporting limit of 2 ppb isn't enough to prove that it is safe in the long term. Granted it's not as much as you get from a can of chicken soup, researchers studying the effects of endocrine disrupters such as BPA are measuring in ppt, not ppb.
I also don't buy the response that it would be just too expensive to manufacture a non-BPA version. It could be either a non-BPA plastic or Pyrex glass. I would be willing to pay $10 more for this. That aside, I'll probably buy one anyway lest the sediment from my French press will kill me first
We did a blind taste testing and found that people preferred coffee brewed in the AeroPress using water at the temperature of 175 degrees F (80 degrees C) so that is the temperature we recommend. Taste is of course personal so if you find that you prefer the taste of coffee brewed using hotter water, use hotter water. It will not damage the AeroPress.
By the way, for people who are think "but I like my coffee really hot", we humans can only drink hot liquids up to about 145 degrees F (63 degrees C). Alex
We manufacture only one version of the AeroPress coffee and espresso maker. The chamber and plunger are made of copolyester (BPA free)and we add a light smokey tint. We started adding the tint about 9 months ago because people preferred the look. "80R08" is our stock number for a case of 8 AeroPress coffee and espresso makers. I do not know why sometimes the stock number is included as part of the product name. Alex Tennant, General Manager, Aerobie, Inc.
Yes the Aeropress contains Bisphenol A. You can find the same answer from google from the inventor and the company. Supposely they had an independent lab test it to show that it have extremely low levels of it. However I will wait for them to make a glass or metal one however they do not seem to signal any moves to do so.
