Coffee Addict’s Guide To Sludge Coffee (Why You Should Start Drinking Sludge Coffee Today?)

It’s not just the taste that makes sludge coffee so good. The caffeine content is also pretty high, which means you’ll feel more alert and energized for hours.

Another reason to drink it? It has a much lower acidity than other kinds of coffee, making it easier on your stomach. This means it won’t cause heartburn or upset stomachs like traditional iced coffees might.

But what really sets this type of coffee apart from all the others is its consistency.

You can always count on your cup of sludge to be thick and creamy like an espresso but with none of the bitterness associated with espresso shots. So if you’re looking for a way to cut down on expensive trips out for coffee drinks, give this new trend a try!

History of sludge coffee

It’s not clear exactly where sludge coffee was invented.

According to the Seattle Times, “Sludge” or “mud” coffee originated in Seattle around 2008. The dark roasts and added ingredients such as chicory and rye quickly became a trend among locals.

While the origins of sludge coffee remain cloudy, it seems that it was an idea that originally started among homebrewers before becoming commercially popular.

It should be noted, however, that while there is not a single agreed-upon origin story for “sludge,” some people have claimed to have created sludge years before elsewhere (one being from Spokane restaurateur Tyler Palardy from 2003 or 2004 when he worked at an establishment called Breadbasket Bakery & Cafe. In addition to claims by employees of Weathervane Diner in Spokane, it has been documented that sludge began appearing on menus as early as 2011. According to a Seattle Times article by a former barista, “Sludge” first appeared at the Capitol Hill Block Party music festival of 2009.

In any case, what is known for sure is that sludge coffee has been commercially available from many restaurants and cafes in the Pacific Northwest since 2008.

While sludge coffee may have initially been a trend among homebrewers, it has become increasingly popular in cafes and restaurants throughout the Pacific Northwest.

How to make sludge coffee at home

The process is simple – dark roast your beans with an extra oily bean, then grind until pulverized into “mud.” Add sugar, cream, and whatever else you feel like.

Sludge coffee is generally served black with cream and sugar on the side to be added by the customer themselves.

It’s also generally roasted extra dark (so that it appears completely black) with an oily sheen, then pulverized into a powder consistency before use. Sludge can either be made with a normal drip coffee machine or with a cold brew

Grind your ‘mud’ to a fine powder consistency. Add 2-3 tablespoons of ground coffee for every 6 ounces of water you intend on making, and add additional sugar and cream if desired. You can also add milk or soy milk instead of water if you prefer your coffee drinks on the sweeter side.

It’s best to use a drip brewer rather than an espresso machine, as it does not require any steam power which can cause problems with burning or clogging. Some people also claim that this style of brewing involves less acidity which is better for your stomach (although many disagree with this idea).

The best type of coffee to use for sludge is a very dark roast, such as French or Italian roasts, which can be bought at most grocery stores.

– For creamier, sweeter coffee, add a spoonful of chocolate syrup to the mix before serving

Sludge Coffee Health Benefits

Sludge can actually be healthier than other types of coffee drinks, such as iced coffee.

This was discovered when researchers found that dark roasted and good quality beans had higher levels of antioxidants than lighter roasts or poorly grown beans.

Also, sludge contains less caffeine which means it has less acidity. Less acid in your stomach means you can enjoy a better-tasting beverage without the added stress to your stomach.

Sludge coffee health concerns

Despite its healthy properties, sludge still isn’t the best drink for people who are trying to watch their weight.

For instance, a mixture of oil and butter in coffee can have high levels of calories which would negate any health benefits it offers. Also, some research has shown that drinking dark brews like sludge can actually increase your LDL (bad) cholesterol which is the opposite of what most people want.

Furthermore, coffee increases your metabolism which means you will feel hungrier throughout the day. If this effect isn’t mitigated with proper diet and exercise then it could lead to weight gain over time.


What is the sludge at the bottom of my coffee cup?

The sludge at the bottom of your coffee cup is known as diterpenes. You may notice that after adding cream or sugar to your coffee, the liquid rises to the top and leaves a layer resembling ground coffee beans on the bottom.

When looked at under light, this layer shows up as brownish-black spots below the liquid’s surface. This is diterpene, which can be found in both coffee filters and be contained in whole coffee beans

Why is there sludge in my French press coffee?

This sludge is created from the coffee grounds and saturated fats that have come to the top of your coffee. It is a natural occurrence, and there’s no need for alarm.

French presses often mix these saturated fats with the brewed coffee, so be sure not to pour it all out until you check first – if you don’t notice anything at all on your spoon or paper towel, then you’ll know that it’s time to drink up!

Is it bad to drink coffee sludge?

Many people drink coffee grounds and sludge as a natural supplement.

It provides nutrients such as potassium, magnesium, manganese, and zinc; it has high levels of soluble dietary fiber; it can help dislodge excessive bile from the liver (which is often caused by the intake of artificial sugars), among other things. 


Coffee sludge is a natural, healthy way to enjoy your coffee. Coffee sludge provides nutrients such as potassium, magnesium, manganese, and zinc; it has high levels of soluble dietary fiber which can help dislodge excessive bile from the liver (which is often caused by the intake of artificial sugars); It also helps with digestion.

Sludge may have some health benefits that are not found in other types of coffees due to its higher antioxidant content.

Despite these benefits, drinking too much coffee sludge or any type of coffee for that matter could lead to weight gain over time if you don’t control your diet and exercise properly.

Overall though, there are many ways people drink their coffee every day without knowing what they’re consuming – so, if you have a chance to explore other options, then it’s probably worthwhile.

Sludge coffee is the way to go!
