Let there be light--to brew my coffee??

Let there be light--to brew my coffee??



































At Carpe Diem Gelato Espresso
My First Ever Siphon/Vacuum/Vac Pot Coffee being made
Carpe Diem House Blend from Cuvee (I want to see Lorenzo do this too?!)


Not the words you think to go with coffee making...

Vacuum
Siphon


Link to Wiki explanation of the Vacuum or "Vac Pot" that begins in Berlin, Germany...
http://en.wikipedia.org/wiki/Vacuum_coffee_maker

What's Old is New (ain't that the truth) in regards to the "Vac Pot" - here's a How To...
http://www.interactivehank.com/docs/images/Dada/VacPot_FAQ.pdf

History of the "Vac Pot" - not just any ordinary percolator...
http://baharris.org/coffee/History.htm

Apparently Bodum has made an electric version or you can still go a different way, tho does that mean non-electric so stove-top or what (must read up on that more - like the mention of it being 'affordable' & the idea that it brews a 'perfect cup'...look up & find $65 to $90)
http://www.specialty-coffee-advisor.com/Vacuum-Pot-Brewing.html

esp like this historical note & now must look up Madame Vassieux & some images of these 'glass balloon' designed double-globe brewers with 'crown' tops from the 1800's...

"Patent filings indicate that vacuum pots were being used in Germany by the early 1800s. The popularity of vacuum brewing spread throughout Europe very quickly along with plenty of notable improvements in design.
Madame Vassieux of Lyons patented a lovely "Glass Balloon" design in France in 1841 consisting of a blown glass double-globe. The lower globe was equipped with a spigot to dispense the coffee. It featured a lovely metal "Crown" on top of the brewer.
The elegance, style, and functionality of these blown glass vacuum brewers quickly removed them from the kitchen. They became prestigious center pieces on dining room tables across Europe, providing delicious full bodied coffee as well as wonderful entertainment for guests and family members alike."

Bodum PEBO


I love it--Steampunk (Retro) Coffee reference?!

Portola Coffee Lab Facebook page...

under About they have listed--a whole bar of Syphon coffee pots (aka "Vac Pot")...
Hario Halogen-Heated Syphon Bar

(note: yes, of course, I have "liked" them & will be "follow" ing them elsewhere too if they're over on Twitter or Instagram or ?!)






photo credit--from the article above...
Steampunk Retro Coffee Explosion - tho they say this is not their bar, as in Portola Coffee Lab

(note: but they don't mention what bar it is, so how to credit them...if they find this, please don't be mad - make a comment & will add where the photo came from - thanks?!)


Some more beauties...lots of gleaming copper...only $500 & what--then there's gold ones too, Oh nevermind...






...history of style & imagination--I'll say?! Thank you Giz Factory for the best steampunk idea yet?!

like the silver/steel one on the left--but this full out Jules Verne/Steampunk version on the right is incredible--I'd love to see that one work & taste that coffee...

(note: we sooo need one of these for the next Steampunk Festival at Cite des Arts in Lafayette, LA... I would never leave, I'd be sitting in front of this coffee machine the whole time I think - ah now how to make a steampunk costume to go with steampunk coffee making...hmm...must work on that idea?!)

yet another coffee article/blogger My Coffee Pro on brewing in a siphon/vac pot/coffeemaker...curious how things come explosively into the (coffee) consciousness--when today is the 1st day I ever remember seeing one & for sure tasting coffee from one...this dated Dec 2012...






Step 1, 2, 3...from Bellina it says on My Coffee Pro page, if you scroll over image...


Link to 185 page thesis on Turkish Coffee Brewing Machines from a Design perspective submitted in 2005 - didn't read it all, but the photos & drawings of all those ancient coffee makers was wonderous to see
(my sidenote: I get an itch to start collecting when I see all these photos/drawings--of old coffee makers or drawings of them, it's a good thing I don't live in Doha, Qatar anylonger or I would be sooo tempted to start scouring the Souks of the Middle East & beyond for them...)

http://library.iyte.edu.tr/tezler/master/endustriurunleritasarimi/T000328.pdf

Note: go to page 62 for the Glass Balloon Coffee Maker History & Patent drawings

Madame Vassieux's glass balloon patent drawing is referenced with this source below on page 65 of the thesis too...

So went to search Amazon.com & found a book title by the source reference author names of Bramah E & Bramah J - so perhaps it's this same book (tho no images) called:

Coffee Makers: Collector's Show-Case by Adelaide Del Sant; E. and J. Bramah(1995)



Or are these siphon/vacuum pot/vac pots just perculators or double glass perculators - as it says in this link to a Free Fiction book (892 pages?? & none of the illustrations show up--what's with that...) called All About Coffee by William H. Ukers (curious last name) - was the design from Europe, France or Germany & then came to the USA, See: Make-Right or Tru-Bru pots or others from the 1900's...
http://www.freefictionbooks.org/books/a/20350-all-about-coffee-by-william-h-ukers?start=662

(note: my goodness, this just makes me want to go run out to antique shops in pursuit of a perculator in any form or fashion--but then there is the internet to browse instead, where I am getting sucked in Oh too easily...)


Another link--Good Grief, not only French but a Belgium connection as well...so here under Sorentina Coffee are Bellina Vacuum/Siphon Coffee Makers - mostly with Butane heaters...
http://sorrentinacoffee.myshopify.com/collections/vendors?q=Bellman






from Sorrentina Coffee webpage about $150.00 - so maybe these 'lab experiments' for coffee makers are more affordable than I thought

(note: tho at the coffeeshop today I was told some of the larger commercial beauties can go for 1,000's & up for a whole bar of them even more--say like those in Cali or NYC...sigh...why not LA--not L.A. mind you but LA, as in Louisiana the state...)

I like the Siphon/Vacuum Coffee Bar photo on this webpage--then they bring up Japan & how these are more popular than drip coffee, so another reason yet to go visit Japan or thereabouts in the world (you know for the coffee viewing alone...)


Siphon Bar - is it in Japan? I don't know when pages like Coffee Home Direct don't credit their photos?! Am wondering looking at the photo if the steel containers underneath the glass globes are for butane or some such fire type heaters & not electric...

(note: I'm liking the idea behind the Halogen bulb heated Siphon/Vacuum Coffee Makers--tho does that then become an environmental hazard to dispose of them after their so called efficient use...it's always something--when all I know is I am mesmerized watching one brew coffee this way?!)


Beginning of the You Tube list...

YOU TUBE - Vacuum Pot Brew at Onyx Coffee Bar...

note: I would just watch this--they don't sound like any of them know all what they're talking about even when you can hear them & forget that cackling customer...so yea just watch the process...


YOU TUBE - Making the SIPHON Japanese Distill coffee by Rocanini coffee Roasters

note: I liked watching the Barista girl make this coffee, it was interesting to see her cool it off with a cloth at the end & then the mention of Physics 101...it is like watching a Science Experiment--only you know you're gonna love the end product that you can drink, because it's super clean delish coffee...


You Tube - Belgium Royal 4C Cafe...a different type of Vacuum/Siphon coffee maker...

note: gravity & vapor in action with musical to go along with that ending in a pink cup, lovely presentation...can you imagine this all after a dinner party or any party--tah dah?!


You Tube - BODUM PEBO vacuum coffee maker 1208

note: Theatrical Coffee...I'm gonna be all about this kind of Theater--tho now after I've seen the fancy ones I'd rather watch them instead?!

You Tube - then there's Ed & his Cona Vacuum Coffee Maker in Action.mov...


You Tube - Japanese Siphon Coffee Maker with Halogen Beam Heater - HARIO Glass Co., Ltd... 

note: all in Japanese with Hario glass company at a convention sounds like...so they call it a Japanese Siphon Coffee Maker & describe the Halogen bulb as a Halogen Beam Heater...

which always when I read/hear the word Beam now I think of the famous line: Beam me up Scotty?!

The End of YOU TUBE list...
as I am slowly getting addicted to watching Vacuum/Siphon pots at work in You Tube videos...it's way/Way/WAY more fun/interesting/fascinating to watch it going on in person?!

Physics of Siphons/Fluid Dynamics...
because--as ever--I was curious...
(perhaps I've been watching too much Big Bang Theory)

First the Wiki explanation...
http://en.wikipedia.org/wiki/Siphon
(note: there is a diagram of a siphon coffee pot...)

Siphon coffee

Siphon coffee brewer: when warmed by a heat source (A), vapor pressure increases in the lower chamber (B), forcing the water downwards (C) and through the central pipe into the upper chamber (D) where it is mixed with the coffee grounds. When the heat is removed, the water flows back down.

"While if both ends of a siphon are at atmospheric pressure, liquid flows from high to low, if the bottom end of a siphon is pressurized, liquid can flow from low to high. If pressure is removed from the bottom end, the liquid flow will reverse, illustrating that it is pressure driving the siphon. An everyday illustration of this is the siphon coffee brewer, which works as follows (designs vary; this is a standard design, omitting coffee grounds):
  • a glass vessel is filled with water, then corked (so air-tight) with a siphon sticking vertically upwards
  • another glass vessel is placed on top, open to the atmosphere – the top vessel is empty, the bottom is filled with water
  • the bottom vessel is then heated; as the temperature increases, the vapor pressure of the water increases (it increasingly evaporates); when the water boils the vapor pressure equals atmospheric pressure, and as the temperature increases above boiling the pressure in the bottom vessel then exceeds atmospheric pressure, and pushes the water up the siphon tube into the upper vessel.
  • a small amount of still hot water and steam remain in the bottom vessel and are kept heated, with this pressure keeping the water in the upper vessel
  • when the heat is removed from the bottom vessel, the vapor pressure decreases, and can no longer support the column of water – gravity (acting on the water) and atmospheric pressure then push the water back into the bottom vessel.
In practice, the top vessel is filled with coffee grounds, and the heat is removed from the bottom vessel when the coffee has finished brewing. What vapor pressure means concretely is that the boiling water converts high-density water (a liquid) into low-density steam (a gas), which thus expands to take up more volume (in other words, the pressure increases). This pressure from the expanding steam then forces the liquid up the siphon; when the steam then condenses down to water the pressure decreases and the liquid flows back down."


Then another argument for an addition to clarify...

Someone asks: Constant Velocity in a Siphon?
And someone's answers here...
http://physics.stackexchange.com/questions/16914/constant-velocity-in-siphon
(why someone just doesn't do this over on Wiki I wonder)

"...It is basically enough to say conservation of mass together with constant cross-section and the incompressibility of water lead to constant velocity. Someone should definitely add this on the Wikipedia page..." Noldorin Nov 13 '11 at 21:39

Thank you 'Noldorin' on The Physics Stack Exchange for the clarification (tho you're speaking to a non-science major...woulda loved to have majored in Micro-Biology tho, or now it's more popular to go for Genetics--or is it ??)

Or on Physics Central you can Ask a Physicist...

How does a Siphon work?

http://www.physicscentral.com/experiment/askaphysicist/physics-answer.cfm?uid=20080512104921

Their answer starts with... "water seeks its level"

(note: I like that kind of simplity?! and further I did not know that the siphon effect stops at about 30 feet or 10 meters...so little wonder there's not a 30 foot siphon coffee pot right?! now am thinking there should be a place for Physics Phunnies & this siphon coffee pot joke made to see how many folks 'get it' - LoL... but then how many folks don't get Big Bang Theory humor either, especially dearest Sheldon...although I'd rather listen to his "friend that's a girl" Amy...)
