We had a viewer ask us if it made a difference one way or the other if you put warm or cool water in the reservoir of a drip coffee maker. Does it change the flavor at all? We tested them side by side to find out if there was a practical difference.
Where do espresso machines and coffee makers go to die? Not in the landfill, if we can help it! At Seattle Coffee Gear, we launched a recycling program last year in an effort to keep as many fully assembled machines from landing in the trash. Many of these are pretty complex — they have circuit boards, electrical wiring and miscellaneous metals that are best kept out of our ground water supply.
Our partner in this venture is Uesugi USA, a Japanese company that (as luck would have it) have a US presence here in the Seattle-area. We pulled Henry into the mix and headed out to their facility to talk about what they do and see how they take these machines apart, break them down to their components and funnel them back into the commodity supply chain as cleanly as possible.
You may recall a post we wrote last year that measured the temperature in a Technivorm thermal carafe, testing it at brew and then tracking it hour by hour to see how the temperature held up over time. In general, we have had a small percentage of customers report that their new Technivorm coffee makers don’t brew hot enough; after testing some returned models, speaking with the manufacturer and testing known working models, we determined that, ultimately, this was largely a question of personal preference.
Some people love their coffee to be really, really hot — and that’s cool! But the Technivorm is designed with a different end goal in mind. Watch as Gail talks to us about what you can expect from this drip coffee maker.
DIY lovers are all into the idea of using lemon juice or vinegar to descale their machines, but while the latter will leave a nasty residue and we don’t recommend it for that reason, the former just isn’t concentrated enough to do as an effective job in as an efficient manner as a concentrated citric acid solution like Dezcal. This is what we find out from Gail, plus she makes freaky faces and it’s worth watching just for that.
Technivorms have been hailed as the drip coffee maker, primarily because they have excellent temperature regulation and are set to extract at just the right heat to get a rich, full flavored coffee without the bitterness (burnt/overextracted) or sourness (too cold/underextracted) that you sometimes find with other coffee makers that aren’t heating up to the ideal temp.
One thing that people have asked us is how hot the coffee is after it’s brewed, and then how long it stays hot when in the thermal carafe. So this week we brewed up a pot and then tracked its temperature throughout the day, with the following results:
|Freshly Brewed Out of Thermo-Carafe||180 degrees|
|1-Hour Later||172 degrees|
|2-Hours Later||162 degrees|
|3-Hours Later||160 degrees|
|4-Hours Later||158 degrees|
|5-Hours Later||150 degrees|
|36-Hours Later||105 degrees in a 75 degree room|
The only drip coffee brewer recognized by the Specialty Coffee Association of America for brewing at the optimal temperature, Technivorm’s Moccamaster features an innovative shower head which delivers water more evenly across the coffee to improve flavor extraction. In this video, Gail talks about the Moccamaster’s features and brews us a cup of coffee.
