The Common Fallacy Of Oily Coffee Beans Explained.

One of the most common conversations that I have had is with people that love 'dark' roasted coffee. Typically this type of person thinks that oily beans and dark roasts are synonymous. This leads to a perception that bolder coffees are darker roasted or that dark oily beans are perfect for espresso. I have to say, these views are so widely held, you'd think they were 100% true. However, they aren't... they're close, but there is more to it than that.
This video seeks to explain where coffee oils come from and help inform the viewer what really brings out a delicious bold coffee.
It is a video continuation of a blog I wrote several years ago: www.sagebrushcoffee.com/blogs...

My preference is to see oily beans… to me, it just taste better to my palate…. Maybe some of the flavour compounds I prefer are in that oily stuff

The new packages, of my dark roast espresso coffee, always have oily beans. When I reach the bottom, there is no more oil. Coffee from a new package always tastes better. I prefer shiny beans.

It appears you're buying old coffee. Oils should not disappear otherwise unless youre taking several months to consume a bag. Properly roasted Dark roasts above 450f ( when oils are beginning to seep out) have a window of optimal flavor from about day 3 to 16 from roasting. I like coffees best in the middle...about day 10.

why does my oily coffee turns dry over time then?

@derpleyew 11 ай бұрын

See even watching this and hearing you explain it I am still inclined to prefer coffee beans with an oily sheen. Whenever I have bought beans that look feel and dry I have mostly not enjoyed the espresso that is made from the drier beans. When I use oilier beans it tastes better, to me at least. I will try and be more open to a more dry looking roast lol

Don’t entirely agree, when referring to darker roast beans, that oily flavours is bad thing, or that causing a bitter taste is a bad thing! That’s exactly what I love and a sign of freshness in a dark roasted bean. I would have nothing less. Yes it’s a matter of taste, flavour is personal thing but also researched it. I know the source of my dark roast, I buy it fresh from being Datkly roasted, it’s dark, it’s oily. But that’s what I specify to my coffee roaster - and the bitter flavour I love. Also btw oily flavour is not purely a sign of stale beans / perhaps on light roast but most oil from freshly dark roasted beans come from within the heavily roasted bean, that combined with sudden contact with oxygen increases the oiliness- yum tasty stuff.

the main thing he did not explain properly is that dark beans have shorter shelf life. unless your talking about italian coffees such as Kimbo, illy and Lavazza which treat their beans with nitrogen..... and that preserves the flavours much longer. dark roast that is fresh will appear extremely oily on the surface BUT the inside of the bean contains less total oil content and humidity. applying intense heat is a DRYING PROCESS. when put a steak on the BBQ, blood rises to the surface, that does not mean it is a bloodier steak. the same applies to the coffee bean.....

Trevor - I bought it from Chemex directly. We sell a bunch of Chemex items and I ordered one of these for myself recently. I'm afraid to sell them, because they seem fragile, so I feel like I'd spend too much on shipping to make it worth it.

Hi , I recently bought some coffee beans from my store. So I suppose it's not recently roasted. And I've noticed it's gotten little bit oily , even when it's stored in a airtight container and hidden away from light and at room temperature. Is this normal ? Should I be concerned ?

@Salam14r 4 жыл бұрын

thnx for the explanation. now I know why my coffee looks so oily, like I can really see the oil on the surface of my drink. It's not a dark roast, maybe I didn't store it properly or it's an old batch from my seller.

when you roast beans, how much do you typically roast ? 30 lbs 50 lbs. ? do you weigh the beans before and after roasting ?

@SagebrushCoffee 3 жыл бұрын

@beetole, We have several roasters in the shop and roast in all sorts of quantities depending on needs. We generally weigh before and after each roast. A good rule of thumb is 18.5oz green = 16oz roasted beans.

@@SagebrushCoffee from the research I*ve done, it appears that although dark beans appear oily on the surface, they are actually dryer on the inside of the bean, containing 13% less in weight after roasting from your example..... the longer you roast the bean, the more oil and humidity is removed from the bean. the darker bean also grinds faster and when packed in a portafilter poses less resistance, yielding a faster and possibly, underextracted shot.

@milovacc1195 3 жыл бұрын

from the research i`ve done, light roast beans contain more oils and humidity . charring the bean longer will dry out the bean and will also weigh less than they did before roasting . the darker bean may oily on the surface, but inside, the bean is actually drier and lighter in weight .

@Milo Vacc idk who my wife got the last 6kg from but I was not happy at all. We live in Japan so shipping can be a factor. I use an open flame gas camping stove with a small cube manual roaster that recommends appropriately 250g batches. Would you be able to suggest another source? I have 1kg green and 200g roasted. We consume appropriately 60g+ a day.

My question is, does an oilier bean damage my grinder or mean I need to service it more often?

@SagebrushCoffee 2 жыл бұрын

Yes, oily beans can cause the grinds to stick together, which can clog up and eventually damage your grinder. A burr grinder will do a better job at grinding, but it is still recommended to stay away from oily coffee as much as you can.

@WholeBibleBelieverWoman 2 ай бұрын

It also depends on the kind of grinder you have. I just use a small Krupps type electric coffee or spice mill, and beans that are a bit oily do not cause any real problem.
