New Outlets Lead to Better Sounding and Tasting Coffee

Coffee aficionados always grind their coffee before brewing. You should start the grinder first, and then pour the beans in. This ensures the motor is up to speed before it starts, ensuring an even grind and reducing stress on the motor.

Most mornings I’m pretty desperate to taste the first sips of coffee in order to function at all during the day, so I usually start the coffee brewer before the grinder has finished, so that there’s almost no delay between the last grind and the first hot water hitting the top of the pile.

One oddity I had noticed when I first moved in was that turning the coffee pot on slowed down the grinder. The reason seems straightforward. The pot draws ~ 1475 watts, or around 13 Amps. Far more than my entire stereo rack combined, which only gets close to this when I turn the amp on, and otherwise plays around 3 Amps, including the TV!

Anyway, turn on the coffee pot, and the coffee grinder slowed down. Makes sense. The high current draw was causing the voltage to sag (drop) under load. It did however concern me a little so I decided to upgrade all the kitchen outlets. Mind you, this 17 year old house had suffered some use and abuse from prior tenants which made me want to replace switches and outlets anyway. Charred contacts and plastic bits stuck in corroding outlets demanded rehabilitation.

The kitchen outlets were on a 20A circuit, but daisy chained and back-stabbed. Replacing them all with Eaton commercial/residential outlets (including GFCI where required) has in fact had a meaningful improvement in my coffee experience. Now when I turn on the pot the grinder doesn’t slow nearly as much as it used to. Not sure if I can taste the difference, but I can sure hear it and it makes me sleep more comfortably knowing that there’s less heat and loss in the circuit.

Of course, I’ve done the same in the home theater / stereo room as well. Can’t say I’ve measured a difference, but knowing that the poor connections and old outlets are gone makes me happy.

I’m not ready to recommend boutique outlets to anyone, or boutique wiring methods. I am however saying that getting well made (at least Residential/Commercial), modern outlets that are not back-stabbed for an old home is probably more than worth it.

My next step is making sure my microwave and coffee pot are on the same circuit so there's no voltage mismatch.... 🤣🤣🤣🤣


There’s some organization that published recommended amounts of coffee and I worked that out on my pot to be 6 grams per marked (European) cup. So every morning I make 6 cups of coffee, which is 36 grams, which works out to about 2 mugs worth.

They also recommend an optimal water hardness which in LA was 5x more dissolved solids than recommended. I used Zero water and blended with other sources to get to the right amount. LA water is also so hard you have to descale your coffee maker 2x as often.

So, water temperature and time, dissolved solids, correct coffee weight and grind, and good outlets.  It all matters. 😂

I'm straight into the tea and sometimes drive dozen miles to friend with well on property to get well water for my tea. Water from the plastic bottles even if it has high-end price tag would not work. Must be running FRESH water only. 

Besides that the tea must be FULL LARGE LEAF only from the best in the world tea regions like Shri Lanka.

As much as I like tea in the morning, I like pot in the evening. Pot gives me ability of pure listening without any criticality of sound leaving only enjoyment of music and musicians.
