I ran my first test run in the Bodum Vacuum brew tonight using only water (no coffee). I had a hard time getting a good seal between the stem and the gasket. Are there any tricks to getting a good seal? Without the seal the water will not rise into the top chamber. Thanks. -- Kevin
Kevin I use the electric model so it might be a bit different but. stem and gasket? hmm that's odd. mine the stem has the gasket on it and it shoves down into the bottom part. anyways.... make sure everything is clean, no dust or shipping material 'parts' stuck in there. no tape etc etc. give it a firm press down but not too hard don't want to break anything. sometimes a rubber seal needs a use or two to 'condition' it. try running it a few times, if it still don't seal you might want to take a drop or two of olive oil or any cooking / food grade oil and very lightly make a super thin coat on the gasket and try it that way, it should seal then. Aaron
I never had a problem with a seal on mine. I always give a little twist as I put the top bowl on. Try putting a few inches of water in the bottom bowl, then put the top on and pour in some water. If the water drains into the bottom you know you have a bad seal and can try some oil or maybe wetting the seal first. It is easier then repeatedly heating the thing up to check. Steve On 11/8/06, Kevin wrote: <Snip>
thank you for the help. I'll try both methods, olive oil on the rubber gasket to help make a seal and pouring a litte water in the top chamber to see if there is a seal...I'll have more time to play with it this weekend. Thanks again. -- Kevin
Are you using the alcohol burner and stand, or a regular stove? The burner and stand provides a small point of flame right in the center of the pot, directly below the stem. You can watch the bubbles go right up the stem and out the top without building any pressure in the bottom. If you hold it slightly off center so the bubbles do not go up the stem it will work. Then again, if you are using a regular stove.... Bart On Wed, 8 Nov 2006 17:12:05 -0800, you wrote: <Snip> water <Snip> the <Snip> the <Snip>
Bart, I'm using a flat top electric stove w/a wire grid. I set the brewer up w/water in the bottom and no coffee just to get a feel. In order to get the water to rise I need to apply downward pressure on the top chamber (to form a good seal). However, I didn't have much time to mess with it last night and used room temp water to start with and brought it to a boil (SM recommends using near boiling and the burner on low). Tonight I'll put near boiling water in the bottom and wet the rubber gasket. -- Kevin
I've never had trouble with the seal on my bodum santos. I find that when I pour near boiling water into the bottom chamber, that the steam that rises wets the lip that the upper portion seals to. I just give it a little twist and it start rising almost instantaneously. I had to adjust my twist, because if I turned more than an 1/8" that I had troubles releasing the seal after brewing. -Branden On 11/9/06, Kevin wrote: <Snip>

We have a flat top electric stove, and quite frankly I was afraid and amazed when Ben stopped by one day and showed me a thing or two about roasting coffee, and brewing coffee. He took my brand new Bodum and set it right on the surface of the flat top range... Geesh.. I would not even go close to it... Stood across the kitchen while it heated... However, it performed admirably. Even though the burner turned red under the pot, everything functioned great ! No cracks, no explosion, no breakage. The coffee was wonderful :) PeterZ Kevin wrote: <Snip>
Peter, Yeah, the Bodum Vacuum brewer works great (don't know about the taste yet). I tested it last night after soaking the gasket in cold/hot water (alternating) and filled it with some old store-bought pre-ground coffee and it worked like a charm. It's entertaining to watch the brew process, like a Mr. Wizzard or Bill Neigh the Science Guy project... -- Kevin "I got a fever and the only prescription... is more cowbell" -The legendary Bruce Dickinsonhttp://www.funnyhub.com/videos/pages/snl-more-cowbell.html
For those interested: Okay, I brewed my first batch of coffee in the Bodum Santos Vacuum brewer with leftover whole bean Gevalia b/c I haven't had time roast yet this week (that's how it is with a four-week old). Though the coffee wasn't fresh, the Bodum brewed a VERY clean cup. My typical morning coffee is brewed via a FP, so the vacuum brew was a nice change of pace. The coffee was smoother and not as bold as when brewed with a FP. For my taste, I prefer the FP during the week when I want a strong, bold coffee to start the work day but I really enjoyed the Vacuum brewer this Saturday morning. I plan to use it on the weekends when I have more time to sip and enjoy the cup. Tomorrow I'll prepare a side by comparison of the two brew methods with homeroast (if I get a successful roast as I'm still learning the Gene Cafe). Oh, one other thing, the vacuum brewers are neat to watch in action. I'm a physics geek and it's entertaining to watch the water being forced up the stem and then drain back down when the pot cools. I'll never tire of that...

Kevin, It doesn't drain back it is sucked back by the vacuum created by the temperature differential. One thing I like about the older pots is they really rumble at the end of the trip south. Les On 11/11/06, Kevin wrote: <Snip>
Les, They (vacuum) brewers make an amazing cup. Different than anything I've had before. I think I'm slowly leaning towards the cleaner cup they make as opposed to the FP. I like the two methods b/c they can give you a different feel for the same bean depending on one's mood. -- Kevin "I got a fever and the only prescription... is more cowbell" -The legendary Bruce Dickinsonhttp://www.funnyhub.com/videos/pages/snl-more-cowbell.html
HI, I do not understand those that claim that vacuum brewed coffee is not as bold as FP coffee. In my book fp produces coffee with better high notes, but not as much body as base notes like my vacuum brewer currenly also a Bodum Santos. Remember to use enough coffee, the 7 grams per cup does only hold for a full pot, not for 2/3 or a half pot my standard amount it takes more beans. I use 35 gram for half a liter water in my Bodum Santos.

Claus, There's definitely more of an taste on the back of the palate for me when I brew with a FP than when I brew with a Bodum Santos. The best way for me to explain it is like drinking an India Pale Ale vs drinking a lager. They both have a 'beer' taste but the IPA is more bitter b/c of the hops. I'd say, for me the FP is analogous to the IPA and the Bodum Santos is like an amber lager. The FP is slightly more bitter (which can be good depending on what one is looking for) whereas the Bodum Santos goes down smooth. This weekend I used the Santos but for tomorrows pre-commute pick-me-up I want the bolder (slightly more bitter) FP. This may not be what others get out of comparing the two methods but the FP is definitely more bitter (read as 'has more bite') for me. -- Kevin "I got a fever and the only prescription is...more cowbell." -The legendary Bruce Dickinsonhttp://www.funnyhub.com/videos/pages/snl-more-cowbell.html
<Snip> In theory, the glass will never get hotter than 212. You can actually boil water in a paper cup set in a campfire, without the paper burning.

"In theory, the glass will never get hotter than 212." Heat flows from a higher temperature sink to a lower temperature sink, in theory and practice. If Witch Hazel has a boiling cauldron of water, and Merlin walks by and tosses in a stone, the stone will absorb heat from the water until the ston= e is also 184°F. Hazel and her cauldron are paying a visit to the visitor's center on Mt. Zebulon @ 14,110ft. If Merlin's magic rock gets any hotter than 184°F, it will clear Hazel's cauldron of all water. The glass utensil has to be hotter on one side than the other, or heat won'= t flow through it. A glass container at Charleston, SC is full of water at 212° F. If you ap= ply heat to cause the water to boil, the water stays at 212° F while it boils= , but the outside of the vessel has to get hotter than 212° F to supply the latent heat of vaporization to boil the water. Since the glass is 212° F on the inside wall and necessarily hotter on th= e outside bottom, you have introduced stress because of the difference in thermal expansion. Heating the water from ambient to boiling in the glass vessel could use up all your rabbit's feet... Should that happen, I hope you're not too far away. It won't be explosive, just a Helluva mess. With a glass top electric range, the flood of cooler water is guaraunteed to crack the top. If you have a gas burner, the flood will extinguish it but won't turn off the gas.

It is going to be pretty hard to raise that inner wall much over boiling temperature because the steam bubbles would have to absorb their entire LHV before leaving the wall. Locking in that inner wall temperature means the gradient can get get pretty high. -- Steven Hay hay.steve -AT- gmail.com Barry Paradox: Consider k to be the greatest element of the set of natural numbers whose description require maximum of 50 words: "(k+1) is a natural number which requires more than 50 words to describe it."

It is very difficult to control residual stresses in glass, so design the "pre-stressed" approach doesn't work. The pots are made out pf a boro-silicate glass which has an exremely small (10e-7 /C) thermal expansio= n coefficients. It would take a very large thermal gradient across the material to generate enough strain in the material to cause ti to shatter.
