Cold-brewed coffee note

leave a comment »

I’ve been making cold-brewed coffee for a while now and have my routine perfected.

I have found that a 1-qt Mason canning jar works extremely well. The jar has measurement markings on the side, so I can easily fill it to the 3-cup mark. And since a canning funnel (which has a large opening) fits nicely inside the mouth of the jar (because the funnel is in fact made to fit canning jars), it’s easy to add 2/3 cup coffee grounds with no spills. Then 12 hours later, I strain, filter, and add water equal to the amount of coffee, which (after straining and filtering) is 2.5 cups. I pour the coffee concentrate into a pitcher and add 2.5 cups water, so I get 5 cups cold-brewed coffee.

The Younger Daughter passed along this interesting tip: add a few springs of mint leaves when you add the coffee grounds. I can’t wait to try it.

Countdown to the Joeveo Temperfect mug

leave a comment »

Back in November 2013, there was a Kickstarter campaign for a double-walled coffee mug that would quickly cool the coffee down to drinking temperature and then keep the coffee at that temperature for a long, long time. The space between the walls contained a wax that absorbed heat (by melting) and then slowly released heat (as it resolidified).

I was eager to get one for The Wife, and today I got this email from the company:

A year and a half ago we ended our Kickstarter campaign for the Temperfect Mug and were launched head first into the trials and tribulations of taking a plan from paper to production. We are committed to delivering a class A product that we know the world will love. We can proudly say we have reached Joeveo’s biggest milestone to date, beginning pilot-scale production of the world’s first Temperfect Mugs!

It seems that we have run into every problem in the book, plus some! From a tree collapsing the workshop to an engineer being injured in the factory, we’ve seen it all. Recently we have been delayed by defects at the production level, and other larger orders taking precedence in the factory line. The latter is to be expected somewhat, as it is the busy season for these facilities. But even through these setbacks we have managed to make progress, and the train is leaving the station. It might be moving slowly, but it’s only going to pick up speed from here.

Over the last few months we have been in constant contact with our sourcing partners and manufacturing facility to make sure the project stays on track. It has taken some serious effort to tie up loose ends and have all aspects of every part finished according to their specifications. These efforts are finally culminating in a pilot batch of 500 Temperfect Mugs, which are being manufactured while you read this. These proto-mugs are slated to be finished August 16th, and will serve as an indicator of how the factory will be able to handle larger orders. If these mugs are defect free, we can move forward to full-scale production, and will finally be able to announce that the mugs are on their way!

We’ve been pretty poor at predicting the shipment date of our first mugs in the past [massive understatement – LG], so we hesitate to make shipping estimates at this point. We do know that once full-scale manufacturing is approved, production should take about a month and a half. Add to that about a month for ocean freight, and then we will start finishing and shipping the mugs here in NC.

We want to give a special thank you to everyone reaching out with their comments, words of encouragement and enthusiasm. It means a lot to us to know people are still excited about the product and the idea. We really appreciate everyone’s patience and support as we forge forward in this endeavor. The first milestone is down and we’re moving onward to full-production and delivery of the world’s first Temperfect Mug.

Caffeine Boosts Memory Consolidation?

leave a comment »

Tracy Vence notes at The Scientist:

Consumption of caffeine after learning could boost memory consolidation, according to a study published in Nature Neuroscience this week (January 12). A team led by investigators at Johns Hopkins University in Baltimore, Maryland, studied the memory performance of 100 participants, half of whom received a pill containing 200 mg of caffeine—the equivalent of two regular cups of coffee—after completing a learning task. The other half were given placebo. The next day, members of the caffeine-pill group were better able to identify images that were the same, similar to, or different from those they were shown during an initial learning tasks than participants who received the placebo.

“The paper demonstrates that giving caffeine after seeing images does improve recognition of them 24 hours later, supporting the idea that it helps the brain consolidate the learning,” the University of Oxford’s Anders Sandberg told BBC News. “However, there was no straight improvement in recognition memory thanks to caffeine. Rather, the effect was a small improvement in the ability to distinguish new images that looked like [the old ones], from the real old images.”

And as National Geographic’s Only Human blog pointed out, some scientists are questioning the statistical significance of the study’s results on Twitter. One of those scientists, Jon Simons from the University of Cambridge, told The Guardian: “The claim that caffeine affects the consolidation of memories is based on quite a small effect that would really benefit from replication in a larger sample to be convincing.”

OTOH, caffeine doesn’t seem to harm memory.

Matcha for me

with 4 comments

Steve of Kafeneio pointed out to me the health benefits of matcha, so I got a kit: bamboo spoon, sieve, bamboo whisk, whisk stand, and bowl, along with some matcha. It came yesterday—and I could have had it sooner by getting the components at Whole Foods, which also carries it, but I’m an on-line sort of guy.

Last night I had my first two cups. It tastes very good—sort of like wheat grass: a fresh, green taste. I cannot get the foam right yet, but it’s early days. And I do like it: quite refreshing and quick and easy to make (since I don’t do the whole ceremony thing).

Well worth a try. I checked out some YouTube videos on making matcha to see the whisking technique in action, but I’m still struggling.
