I've started playing with coffee making again.  I'm enjoying the french press, but one of the major issues I have is that there's not a way to easily get all the liquid out, and the extraction continues so long as the press sits.  Sometimes I'd like a 2nd cup, or a bit more, but if the press sits for a while it gets bitter.

In my thinking about it I thought I'd come up with a million dollar idea of a reverse french press where the plunger is pulled up and into the lid, stopping the extraction process and getting the grounds out of the way.  I even came up with a cool name:

The French Pull

I was going to talk to a friend about setting up a kickstarter before I did a google search on the term and found that there is such a device, the Tirra Coffee Maker:

Anyone have any experience with it?

I've heard of the technique (French Pull) used with a regular press pot, but never tried it.

While not using a Pull, the funded Impress Coffee Brewer Kickstarter project has a similar approach for a single cup press where the grounds are pressed down into the base to stop the extraction.

Since I backed the Impress project, I'll be able to tell for myself sometime next year how well it works.  It looks like it might be a good solution for a single cup of coffee on the road.

Looks interesting. The problem I've had with my cheap FP, the coffee cools too much for my liking after the 4 minute extraction. An insulated or better quality FP might help with temp loss.

I'm with you on that, and my (now torpedoed) invention was going to be a replacement 'pull' lid for a good insulated clear press like the CHAMBORD Double Wall (as I  like to watch).

Of the two issues you have with normal french press, the Espro press provides a surprisingly good solution to the second. That is it seems to achieve such effective isolation of the grounds from the filtered coffee the coffee does not taste over extracted up to 45 minutes or an hour later.

This is probably because of the double basket mesh filters which are 8 to 12 times finer than a standard french press. Each mesh filter traps some sediment and I expect the thin layer of coffee liquid between the two filters provides further isolation.

The double walled stainless steel is also vacuum insulated to retain heat better than most of the completion.

Most of the coffee liquid can be extracted, but you probably don't want to drink it if you have waited awhile for you second or third cup. If the Espro press is tipped more than 90 degrees and short plunges are repeated, the liquid coffee from below the filter is expelled, almost like small squirts.

I've looked at the Espro, but I still am saddened by all that liquid coffee that's sitting in the grounds.  I really love the idea of the grounds being suspended when you choose to stop the brew cycle, allowing the liquid to drip out.

I think Santa may have a Tirra in store for me, so I'll update you all on my experiences with it.

Well, it looks like they stopped making the Tirra a few years ago, and the only online seller that showed it available was incorrect.

Now looking at what I'm trying to accomplish (immersion brew with full liquid extraction and a halt to the brewing process), it sounds like I'm really looking for a Clever Coffee Dripper, Incred-a-brew, or BrewT.  All are plastic and that bums me out.

My dream device would be a glass insulated contraption with a gold filter.  I suppose I could cobble something together, but I wonder if anyone has any suggestions.

Bonavita has a porcelain version of the Clever coming out soon.
