Bitter Espresso: The top 3 reasons your coffee tastes bitter

A certain amount of bitterness is actually an essential part of the balance of coffee flavour - just like with chocolate, wine or beer.
But what about times when bitterness dominates the flavour of your coffee?
In this video, Josh explains the top 3 reasons your espresso coffee might be tasting particularly bitter, and what you can do to bring back the balance between sweetness, acidity & bitterness.

Interesting video. I'm still going to buy a new tamper.

The proper way of determining whether or not you have the proper number of tampers is using the mathematical equation N+1 where N is defined as the total number of tampers you currently own.

Thanks again 7 Miles. Keep em coming. This was good reminder for me that you can grind too fine. I think this is what happened with my favourite bean, La Linda. It was perfect the first two bags, then I when finer with a different bean and forgot re-set it. Bitter notes appeared that weren't there before.

[@SevenMilesCoffeeRoasters]

[@abittwisted]

Dialing in my grind with my Kitchenaid Grinder attachment. I find it is more consistent than the burr grinder. It takes a little longer but it grinds slow, smooth and cool. I have a funnel to funnel into the portafilter. I use about 15.5 grams of bean. My machine is an older La Pavoni Pub and it does not have a way to change the temp or time of brew. It seems to take about 31 seconds for a 21gram double shot. I have a single shot button, double shot button and a button for manual timing. I have been grinding a bit coarser to allow the brew to pass through a bit faster. At first my grind was way to fine. Im using the Kitchenaid grinder because in the winter my burr grinder clogs up and it is always a pain in the .... to clean it all out. It takes a bit but the higher moisture is difficult. The Kitchenaid grinder won't clog up. Easy to clean too.

I was curious as to why the light roast beans I ran through my grinder made a better espresso shot than Cafe Bustelo. I had never tried Cafe Bustelo before and decided to try some when I got my first espresso machine. I figured it was because Cafe Bustelo is ground finer that my grinder can go. My lowest setting is perfect. Glad I don't have to invest in a new grinder. But, also because it's a darker roast too. Mainly I think it is ground to fine. Which is okay. I can still make a decent Latte with it.

To me it’s been 2 things: 1) the speed at which I express, because if it’s too fast it’s bitter, if I set it to a flow that is slower it’s better 2) too much tamping, I find the less pressure and I guess more fluffy the bed the better it taste.

Starbucks French Roast is my favorite coffee but it's a challenge to make a decent espresso that's not bitter. I upgraded my grinder to the Sette 270wi and using an old Capresso Cafe Select Espresso Machine turned out an awesome espresso. Then I upgraded to a Bezzera BZ10 and have struggled ever since. I've reduced the dose and the brew time, done cooling flushes, and tweaked the grind size which have all helped, but so far nothing has eliminated the bitterness and captured the true flavor of that coffee. The struggle continues.

Cleaning is a basic step that should be done without thinking. A poorly roasted coffee is the #1 reason for bitter coffee, period. The other variables are easily controlled by any competent barista.

[@media1981]

Let's face it. No matter how well you extract it, there's always some bitterness exists. I have tried many coffee espresso in places from local cafe to famous specialty coffee house and never tasted any espresso that has zero bitterness. Of course there are other notes of flavours alongside, but bitterness is inevitable or your tongue isn't sensitive enough.

[@lentonwienand762]

Hi, Len from Johannesburg with a problem. I'm using medium roast beans and getting little or no crema,. Furthermore unless I tamp very gently in the cup, water doesn't pump through. I have a Breville Cafe Venezia with 15 bar pressure which is far greater than your recommendation of 6-9 bar. I using an old hand crank grinder set to fine but generally grind is a tad inconsistent, but I don't believe that's the problem. Your comments will be appreciated. Kindest regards.

[@SevenMilesCoffeeRoasters]

Great questions Len! Crema will come from pressure, so 15 bar should... but seeing as you're not and then tamping light I'm going to assume perhaps the resulting shot is blasting through?.... BUT if it's not then I assume your grind profile is too fine, therefore becoming exceptionally dense. With the added bar pressure, I say its potentially compacting it and slowing down your espresso shot even more. If possible, I would personally dial back the bar pressure, if you're not able then going coarser on the grind should speed up the espresso shot flow of water. Then you should be able to tamp normally. Ideally you should never be changing your tamp pressure, as the errors in espresso shot time is coming from the grind profile, so the fix is 99% of the time at the grinder itself. End of day, you really want a flavoursome cup, so flavour is end goal, changing the grind profile will help the most here. :) Crema doesn't always signify a great espresso. I can pull crema on almost all coffees but certainly not all taste great unless dialled in correctly :)

Greetings :) Question: Yesterday; I made a delicious "Americano." Breville Pro grinder size # 13; 17 grams (weighed) freshly (home ground) dark roast beans. It gave me a lovely "burnt sugar" finish on my palate. Yum. Today: Same steps; bitter coffee. Ugh. Pour it down the sink; try again. Ease up on the tamp; the pressure needle went up too high for the first cup--compared to yesterday. Second cup result: Bitter. Ugh. What a waste. I had to make several tamps to level the coffee in the basket--And then give it a light "formal" tamp. I'm guessing that I over-tamped the grinds. did the same thing yesterday. Still....The pressure needle was in the "good" range, and the extraction time was about twenty to twenty-five seconds. I'm also reminded to clean the grinder; it's been about ten days. I use the vacuum cleaner; a bit inconvenient. It works very well--Sucks all of the old bits out quite thoroughly. (Using the small round "horse hair" attachment.) Sorry! My question: Why such a drastic difference between yesterday, and today?

[@SevenMilesCoffeeRoasters]

Coffee will age faster when exposed to different environments. Air, Heat & Moisture. As the coffee degasses as well this will also have an impact on your flavour. Try to keep all variable the same as much as possible and avoid changing your tamp pressure. Try perhaps, adding a 0.5g more coffee. This will intensify the flavour as there is more coffee to be shared amongst the same volume of water passing through. Hopefully then you were won't be suffering over-extracting flavours coming through.

I am really struggling with my new machine! I have a Breville Barista Max - Bean to cup - I have bought some local coffee from a roastery - I am using 18g for a single shot - mid range grind - it's horrible and it's flowing in 16 seconds! What am I doing wrong?! Pleeeeeeeeeeeeeease?!

[@dennissmith7219]

On my Barista Pro, I can pull a “perfect” shot with 18 grams, 25 to 30 seconds and looks great but it yields about 42 to 50 grams liquid and is bitter. Is my grind off?

[@ezbacc]

the normal ratio is 2:1 in about 25 seconds. so if you weigh 18g of beans, you should aim for 36g of liquid coming out in 25 seconds. if youre getting 40+grams of liquid from 18g of beans in 25 seconds, the water is flowing really fast through your puck - which means your grind is too coarse. It wouldnt necessarily taste bitter, but should be a really weak tasting espresso. Try making your grind more fine and aim to get 36g of liquid out instead.

[@sstraubi]

I am new just got an awesome entry level machine (Breville Barista Pro) and making 2-4 latte/cappucino's a day for a month now. They are now tasting bitter i think - taste like battery acid Id imagine. WHen I read the guide it makes me think it is under extracted since the shot pulls fast (starts around 7 seconds finishes at 17) and does NOT look like 'warm honey'. so i grind finer, tamp harder tastes worse. What do you think it is??? Also almost no crema...using Super Crema by Lavazzo. Appreciate your tips!!

[@SevenMilesCoffeeRoasters]

A 17 second extraction time will result in under extracting most coffees, so grinding finer is the right idea in theory. If you're getting no crema with the setup described then the coffee is almost certainly stale. If possible, grab a fresh bag (ideally from a local roaster that labels the roast date on the bag) and that should bring back the flavour (and the crema). The reference to 'Super Crema' in the blend name is usually Italian roaster code for added robusta - which is a type of coffee that typically produces a bigger crema, but also usually comes at the cost of extra bitterness. Hope that helps...

[@adarshshah9763]

I've found brew times for Breville Baristas do not sync up with what you would expect. I have really fast pulls but they are not sour at all. "Normal" times (25ish seconds) can result in an over-extraction. Bottom line, extraction time is a guide, not a rule...experiment and do what tastes best!

[@SevenMilesCoffeeRoasters]

Do you know what brew ratio you're using? (i.e. weight of coffee in the handle / weight of liquid espresso). Just based on the flavour description it sounds like it could be underextracted due to not enough water (aka ristretto). Light roasts are more difficult to extract and can have a salty, dryness to them when they're underextracted.

what about for medium roast and brew temp range? i'm using an Izzo Alex Leva. thanks.

[@SevenMilesCoffeeRoasters]

I generally start around 93-94C and adjust by taste. While PID controls are very accurate, in most cases they read the temperature at the boiler and then apply an 'offset' to account for the fact that the water is cooler by the time it gets through the group and into the bed of coffee - these variances mean that it's often not an exact comparison between machines. The team is working on some research on espresso brew temperature - so we'll have more on this soon.

I still can’t find the reason why my coffee taste bitter when i pull the shot in less than 30 sec. I always pull ristretto shot 1:1 ratio, with medium roast Sumatra Blue Batak. Here is what happen. Pull 15-20 sec (sour, lack of body, thin). Pull 20-30 sec (bitter, ashy, no sweetness). Pull 30-35 sec (sweet, full body). Pull over 35 sec (bitter again). Question: how is it possible it taste bitter when i pull it in 20-30 sec range? Where it should be the golden range for pulling a shot.

[@SevenMilesCoffeeRoasters]

Hi, there is no golden range in terms of 'recipe' (i.e. brew ratio & extraction time), as the extraction depends on other factors, such as water chemistry, coffee roast (& age), density of the coffee and a whole lot more. The short answer: if it tastes good at 30-35 sec - go with that.
