Hi,

Anybody else get this on there coffee? Kind of a gross looking film floating on the top of the coffee? Wish I could figure out whats causing it. I'm on Rural water....so not coming out of the ground.

Any ideas?

GREASE! OR AN OIL THATS WHAT I HAVE BEEN TOLD.

That is oil from the coffee beans. Nothing to worry about. Most of it is filtered out if you use paper filters. If you use a gold filter, you get more 'oil'.

I have the same thing.....and It's NOT from the beans. I buy folgers sealaroma coffee,...and every morning have a near metalic or shiny layer on the top of my mug.

If it was from the coffee beans.....you'd see a layer in every mug. I can go down to the coffee shop down town, or any restaurant and have a perfectly fine cup of joe.

My office coffee has this film if I use the tap water. The city water is very hard. Not an oily film but a scummy film that will come off if you put a napkin on it. Nasty.

No film if I use the water from the water cooler for the coffee. It can sit for hours with no film.

Same thing at home; softened water-no film, straight from the well- film if it sits in the pot for more than about 30 minutes.

It is oil from the beans.

The reason some people see it and others don't is the water temperature. The hotter the water, the more oil you see. This is true even after the coffee has been brewed. You might not have any in a fresh brewed pot, but after that pot sits on the warmer long enough, the temperature goes up, and the oil appears.

I was once told a couple of pennies between the pot and the burner will reduce the amount of film. Worth a shot?

I saw the same film on coffee at my favorite neighborhood restaurant every morning for many years. After the first slurp it disappeared. Wonder where it went? The coffee tasted fine.

Other restaurants in the same area, in the same water district, and my home in the same area, did not have this film on their coffee.

Try putting a tablespoon of lemon juice in your water before heating the water. Then try using the brown filters.
I beleive the film is calcium carbonate that is released when the water is heated. The lemon juice will solve your problem.
Make a pot and let us know.

I found this film in Iowa and the acid in the lemon juice solved the problem.

But what does the lemon juice do to the taste of the coffee?

Dude you're drooling.

YOU GUYS ARE FUNNY...LEMON JUICE, PENNIES, WATER TEMP.... HEHE
The only thing that causes film of this type on the surface is water quality. try brewing your coffee for just one day with bottled water.
you will not have a film. this is all about the water you use or the way your water is filtered or treated. end of speculation... water temp was a good one though JD.

Light reflecting off of Venus, that passes through swamp gas causes this filmy appearance on top of a cup of joe in the mornings. Nothing to worry about.

Look under dark roasts. I am not sure whether to believe this or not?:)

I think it has more to do with the type of beans. A good quality dark roast will have the oil on the top. I like it hot, dark, and greeeeasy. That's coffee.....none of that warm brown water.:shame:

Oil ~ Maybe it is a additive that GW ask the coffee makers to add to irritate "The Democrat", so that he can start the day out on his left foot instead of on the right foot! :)

Heh heh heh. Coffee with an oil slick. Now that sounds appetizing:)

I use a Carafe style brewer and have no problems...
Have you guys ever tried Jamaican Blue Mountain coffee??
Hard as #### to find and expensive (except in Jamaica) but absolutely amazing coffee. Has won the top coffee award for several years running...wish I could remember where I read that...but DAMM the stuff is good.

I never tried it. I don't think I have seen it in the stores. I have tried Kona when I was in Kona though. I thought it was rather good.

I get a pound or two of Blue Mountain every year from a friend of mine who travels to Jamaica several times a year. It is IMHO the best coffee in the world.

I used to get coffee from the foreign ship's captain when I had a job inspecting ships. It had a LAYER od thick oil on it,..my boss said to drink it to not offend the captain (lots of posturing in this job) I was told it was the oil from the beans and you got a lot more of it from the foreign captains was that they steamed the beans to "brew" coffee. I also understand that some coffee makers operate to cause a bit higher heat (so maybe the difference) Also if you do this AND have hard water the mag and ca. salts will combine with the oils (a bit like making soap).
