Rinse and Dry Every Day!

In the bad old days, I was in a rush to get my coffee and go.  I would leave the wet coffee filter filled with wet coffee grounds in my coffee maker to deal with later.  I would empty as much coffee as I could get out of the pot, but I wouldn't bother to rinse it out before hitting the road.

Now, I have learned to take better care of my coffee maker.  I take a few seconds to empty the filter basket and give it a rinse right after making coffee.  I also rinse out the coffee pot.

Why not do these things right away until waiting until later?  A little bit of timely cleaning will reduce unwanted flavors and odors from stale coffee and coffee grounds from making their way into your coffee.

Not only do I rinse the filter basket and coffee pot right after making coffee, but I also store my equipment in a smart way.  I leave the top off of my coffee pot, and I leave my filter basket exposed a bit so it can dry thoroughly.  Here's a photo of how I leave my coffeemaker every day before I leave:

See how the carafe has the lid removed and the filter basked is slid out slightly?  This allows everything to dry out quickly to nip algae, fungus, and mold growth in the bud.

Monthly (or Quarterly) Cleaning with Descaling Solution

Another important routine maintenance item for your coffee maker is to clean it with vinegar or descaling solution about once every 1 to 6 months, depending on the harndess of your water.  I once lived in a house where the water was so hard that I had to clean my coffee maker every month, or the water flow rate would significantly decrease due to mineral build-up in the coffee maker.  After a couple months without cleaning, it would take 15 minutes to brew a pot of coffee!

At my current house, I need to clean my coffee maker every 3 months.  Be sure to clean your coffee maker occasionally to remove mineral deposits.  This will shorten your brew time and make your coffee taste better.  Here is my latest article about how to clean your coffee maker.

Ninja Coffeemaker Clean Light: What to Do?



 The "clean" light came on on my Ninja- what should I do?
The "clean" light came on on my Ninja- what should I do?


Today the "Clean" light on my Nija coffeemaker came on.  At first I wondered if this meant that my coffeemaker was clean, but I quickly realized that the "Clean" light means that the coffeemaker has a problem needs to be cleaned.

I went to the Ninja website to find out what to do.  It turns out that the Ninja has a sensor to detect calcium build-up.  That is what makes the clean light turn on.  Calcium deposits can restrict the flow of water in the Ninja and make brewing less effective.

Calcium build-up can form if you are using hard water for brewing.  I used my coffeemaker for about 3 months before the clean light came on for the first time.

So how do you clean your coffeemaker and make the "clean" light turn off?  Fortunately this is pretty easy.  You can run descaling solution or white vinegar through your coffeemaker and this will dissolve calcium deposits.

My grocery store didn't have descaling solution, so I picked up some white vinegar instead.  I filled the reservoir up to the cup line (11 oz), and filled the reservoir with water up to the max clean fill mark (30 oz).

If you use descaling solution instead of vinegar, follow the directions on the package and fill up to, but not exceeding the Clean Cycle Max Fill line (30 oz).

With the reservoir filled with the vinegar and water mixture, I pressed the "clean" button to run a cleaning cycle.  This is the same one that is lit up when the coffeemaker needs cleaning.

It takes about 8 minutes to run a clean cycle, heating up the solution and running it through the coffee maker.  At the end of this clean cycle, I was happy to see that the clean light turned off!  I rinsed out the carafe, filter basket, and reservoir since they all smelled like vinegar now.  I also filled the reservoir with water and brewed a cycle with only water to clean out all of the vinegar.

When the Clean light on your Ninja comes on, be sure to run a clean cycle right away with either vinegar or descaling solution.  This will keep your coffeemaker running smoothly.

Ninja Coffeemaker: Brewing Temperature and Serving Temperature

When I had my previous coffeemaker, the Melitta with cone filter and thermal carafe, I was excited to try out my non-contact temperature gun to check out the brewing temperature and the serving temperature.

Here's what I found measuring my Melitta Coffeemaker:
Melitta brewing temperature:  158 F
Melitta serving temperature:  152 F

The brewing temperature was measured in the filter basket during brewing, and the serving temperature was measured in the thermal carafe just after brewing.  Of course, the temperature of the coffee will drop a few degrees further when you pour it in a cup.

Now for today's question:  What is the brewing and serving temperature for the Ninja Coffee Bar?

Ninja Coffee Bar: Measuring Coffee Temperature

This was pretty easy to test.  I brewed a pot and got out my non-contact temperature gun again.  Here's what I measured for temperatures on my Ninja Coffee Bar:

Measuring Water Temperature During Brewing in Ninja Coffee Bar

Ninja Coffeemaker Brewing Temperature:  175 F
Ninja Coffeemaker Serving Temperature:  160 F

Again, the brewing temperature is the temperature of water in the filter basket during brewing, and the serving temperature is the temperature of the brewed coffee in the carafe just after brewing.

Comparing these coffee temperatures with what I measured on my Melitta coffeemaker, you can see that the Ninja brews about 15 degrees F warmer.  The coffee in the carafe is about 8 degrees warmer from the Ninja than for the Melitta.

So is this good or bad?  The coffee from the Ninja tastes great and is not scorched, so I don't think 175 F is too hot for brewing.

Actually, the brewing temperature for the Ninja and the Melitta may be more similar than my measurements show.  I measured the Melitta brewing temperature with coffee grounds in the filter basket; I measured the temperature of the water in the filter basket with NO GROUNDS for the Ninja.  I think the coffee grounds would provide a lot of surface area and tend to result in a lower temperature measurement.  So taking this into consideration, I would say that the brewing temperature for Ninja and Melitta are actually pretty similar.

I want to double check my temperature measurements, and I like to play with my temperature gun, so I look forward to taking more temperature measurements.

Contigo Travel Mug FAIL

Today, I had a bit of a problem with my excellent Contigo travel mug.  This mug has worked great for several years, keeping my coffee hot and making it impossible to spill.  You see, the Contigo travel mug has a trigger mechanism in the handle- no coffee comes out unless you squeeze the trigger,  You can even turn the mug upside down, and it won't leak .  At least until today.

I pulled into the parking space at my office and noticed some drips of coffee on my car seat.  I figured I simply neglected to tighten the lid and gave it a bit of a twist before heading in to my office.

But at my office, things went bad really fast.  I ended up spilling coffee on my lap.  I'm sure this looked ridiculous!  The cause:  the Contigo travel mug failed.  I took some pictures to show exactly what went wrong.

The problem appears to be a stress fracture along the attachment of the blue threaded ring to the black lid assembly.  Coffee was leaking out, and there was nothing that could be done about it.  I ended up with coffee in my lap to start the day...

This was a great coffee mug for 2012 to 2017, but is no longer usable.

Now for the next question:  will Contigo send a replacement?

Stay tuned to find out if Contigo is as good of a product as I once thought...


Update:  After sending a second round of photos, Contigo agreed to send a replacement lid for free!  They were out of the original blue color, so I went with gray.  The replacement lid arrived today, 5 weeks after the leakage event.  Thanks Contigo, I'm still a fan!

My free replacement lid arrived!

My Coffeemaker Upgrade


My Coffeemaker Upgrade

My Old Coffeemaker...

My Melitta Thermal Coffeemaker was a great coffee maker in the $50 price range.  It has a cone filter and thermal carafe, and made great coffee for years.  I stand by my evaluation that this is the "best value" coffee maker in terms of features and quality that you get for the money.  Here is my review of the Melitta Thermal Coffeemaker.

My New Coffeemaker...

A couple months ago, I found that my Melitta wouldn't turn on.  I suspect that the computer got zapped by a power surge or something.  My first thought was to get another Melitta since I liked it so much, but my wife bought me a fancier model as a present: the Ninja Coffee Bar with Thermal Carafe.

Ninja Coffeemaker Review

Ninja Coffeemaker Review

My Melitta Thermal Coffeemaker was a great coffee maker in the $50 price range.  It has a cone filter and thermal carafe, and made great coffee for years.  I stand by my evaluation that this is the "best value" coffee maker in terms of features and quality that you get for the money.

The Ninja Coffeemaker is a step up in price, around $150, and provides a step up in features. I like the removable water reservoir of the Ninja.  It is easy to take the reservoir to my refrigerator to fill it with filtered water.  The reservoir then snaps back in place on the Ninja coffeemaker.

Another great feature is the easy size selection knob.  You can select a single cup, a travel mug, a half carafe, or full carafe.  Most days I select the travel mug size to fill my mug for my drive to work.  The other day I was running out of coffee beans, so I made the smaller 1 cup size.  The Ninja automatically uses the correct amount of water to brew the selected amount of coffee.

Another interesting feature of the Ninja is that it has a stand where you can set a coffee cup during brewing in place of the carafe.  This makes it handy to brew a single cup.

The Ninja came with a permanent gold cone filter.  This can be used instead of paper filters, but I still use paper filters.

There are several types of Ninja coffeemakers available, I went with the thermal carafe model to keep my coffee hot when I want to use the carafe.

The Ninja coffeemaker has a tube that extends into the carafe that helps keeps coffee hot as you pour it**.  This is just one of the many details that the Ninja coffeemaker has that makes it a great coffeemaker.

**Update:  I was looking at this more closely this morning, and I realized that the tube is used to direct the coffee to the bottom of the carafe during brewing.  This helps it stay warmer.  When you pour the coffee from the carafe, the tube is not used.  The lid of the carafe has an opening so the coffee pours directly out.  This is a cleaver design!

The Ninja set also includes a milk frother for making coffee drinks such as cappuccino.  The milk frother is a "hand pump" style frother and is a separate item that is not attached to the coffeemaker.

Another feature that the Ninja offers is an "Over Ice Brew" setting.  This brews stronger, more concentrated coffee that can be used to make iced coffee drinks without getting watered down.  If you like stronger hot coffee, you can select the "Rich Brew" instead of the "Classic Brew".

The Ninja Coffee Bar can brew great hot coffee with its cone filter and thermal carafe.  It can make iced coffee drinks using the "Over Ice Brew" setting.  The handy size selection knob lets you dial up a full carafe, half carafe, travel mug, or cup.  The Ninja takes the right amount of water from the water reservoir- no need to measure water.  The Ninja has a fold-down stand so you can brew a single cup right into you cup without using the carafe.

This coffeemaker is rated nearly 5-stars on Amazon, and I can see why:
