Chemex’s personal “AeroPress” » CoffeeGeek

Peter Schlumbohm will not be a family identify to enthusiasts of espresso and coffee, however his maximum a success product positive is: Schlumbohm invented the Chemex espresso brewer.

He additionally invented actually masses of alternative gadgets together with: an fast ice maker; the Minnehaha, a cocktailogist tool that blended beverages temporarily by way of forcing the liquids via a high quality mesh display; a cigarette holder designed after the Chemex, the use of Chemex styled mini cones because the filters (lengthy earlier than cigarettes had them inbuilt); or even a girl’s handbag. Numerous his innovations and patents contain refrigeration of quite a lot of varieties and kinds. It makes you surprise the place his first interest was once: espresso or protecting issues chilly?

Schlumbohm additionally designed a somewhat bold automotive, known as the Chemobile (pictured the appropriate). This design wasn’t such a lot a need to get into automotive making because it was once a knock in opposition to what the concept was once in point of fact uninteresting and staid automotive designs of the day. He sought after each passenger to have an enormous view of the encompassing global when using alongside.

He did design quite a lot of espresso gadgets, together with many variants of the unique Chemex. One was once a Chemex with a pour spout extruding from the decrease part of the brewer. Every other gave the look of one thing that would flip the Chemex into an alcohol nonetheless. Many of those gadgets by no means made it previous the strategy planning stage. Person who did make it to production was once known as the Tubadipdrip. What a reputation! I recall seeing a antique advert for it ages in the past and concept on the time, wow, did the Chemex man invent the AeroPress 50 years earlier than the AeroPress man invented the AeroPress?

Hammacher Schlemmer was once a large fan of Schlumbohm and his innovations. They have been some of the first shops to promote the Chemex, his all glass water kettle (nonetheless offered nowadays) and a couple of of his bartending gizmos.

Additionally they offered the Tubadipdrip for twelve months. They even controlled to get the New York Instances to jot down up the brewing tool (PDF Hyperlink), although it reads like a press liberate and no longer a real evaluation or essential have a look at it. So what, precisely is it? Used to be it in point of fact an AeroPress, 50 years earlier than?

Now not in point of fact. The one similarities are a) it brews espresso, and b) it comes to two nesting tubes. And it gave the impression very bad to make use of as a result of like lots of Schlumbohm’s innovations, he by no means did moderately get it proper.

How the Tubadipdrip Works

This tool is composed of 4 components: a big diameter, tall aluminum tube with a forged backside; a 2d aluminum tube with a steel clear out on the backside of it; a steel strainer / clear out tool with no care for that you simply needed to hand dangle for a short while, whilst letting blazing sizzling espresso brew float via it; and a material wrap or cork wrap for the outer steel tube.

It was once marketed as a form of immersion, then float via espresso brewer tool that is also used for cocktail blending (the dude was once large on cocktails), or a stovetop “percolator” espresso brewer. However let’s simply persist with the principle way of brewing with this tool. 

First, insert the smaller diameter tube with the ground clear out throughout the better, forged steel tube. Subsequent, upload espresso, after which upload just-off-the-boil water. Let steep, then stir. After 2 mins, raise the interior tube up (take into account, it was once steel and blazing sizzling, although it did have a catch care for to grab), to let espresso start to float out the ground. To help in filtration, raise utterly out of the bigger tube, after which position the secondary clear out tool (they known as it a “bushing”) to leisure at the better tube’s most sensible opening, and position the interior tube on that to finish the filtration portion of the brew.

Such a lot of threat issues right here. The fabric, aluminum (Schlumbohm known as “glassplated aluminum”) is very sizzling when used with boiling water. In the second one degree of brewing, the tool could be up to 60cm tall at the desk, with an excessively slender diameter, and intensely vulnerable to being knocked over, spilling tremendous sizzling espresso slurry far and wide.

I additionally discovered some further promotional subject matter in this tool, which was once offered in two fashions: a chef’s version (for $7.50 in 1947, or $103.50 nowadays!) or a cork version for $9.50 (that cork added $27.50 of nowadays’s bucks to the tool!). Schlumbohm was once specifically lovely in describing why the “chef’s version” was once the simpler selection: 

“We’re strongly in choose of the Chef Style. Be your personal “French Chef” and tie a serviette across the neck of the CONTAINER”, he wrote. “It seems a lot smarter than any mechanical care for ever may just, insulates smartly, is at all times blank, fits your desk linen and protects as a drop catcher. Most effective as a concession to conference do we provide the Cork Deal with model, hand grew to become from plastic cork.”

Additional on, the literature alludes to imaginable threat from the tool, and the way a large material serviette tied to it will save you scalding burns. 

Unfortunately (or in all probability no longer), Schlumbohm’s Tubadipdrip didn’t remaining lengthy available on the market, and discovering examples to buy nowadays could be a significant treasure hunt. However gadgets like this shouldn’t be misplaced from the historical past of pour over espresso.

There was once possible within the tool, and I don’t moderately know why the Chemex Physician didn’t see it. He even alludes to it within the promotional literature of the time for the Tubadipdrip (Schlumbohm wrote all of his corporate’s promotional subject matter and commercials): he mentions “vacuum kind” brew as some of the brew recipes for the Tubadipdrip.

I ponder whether he explored creating a extra hermetic are compatible between the interior and outer tube. So whilst you pulled up at the inside tube, a partial vacuum would shape within the outer tube, and suck the entire brewed espresso via in the course of the clear out on the backside of the interior tube, to fill that vacuum. By the point you had the higher tube extracted from the decrease one, your espresso could be brewed entire, and sitting within the decrease tube. It could lead to a sooner completed brew, and in all probability much less mess and threat on the finish.

It could be a product to take a look at nowadays, if it hasn’t already been regarded as.
