I was preparing my latest favorite work-suitable drink a few minutes ago, and a drop of tea spilled over the side of the mug and ran down to the base. Naturally it immediately spread around the entire base, forming a ring on the desk. It was easily wiped up, but then I thought—why does it always spread around the entire base to form that unmistakable coffee ring?

It occurred to me that it might just be capillary action with the liquid flowing along the V-shaped channel formed by the table and the edge of the mug. Some googling did turn up the fact that ring-shaped coffee stains from single drops are caused by capillary flow: as the drop evaporates, it draws water from the inside.

But the instant ring from the mug? Either it’s something else, or it’s so obvious no one has throught it worth writing about.

Edit: *sigh* Read first, then post. I was just reminded that capillary action specifically refers to fluid moving against gravity. Any other thoughts?

The Coffee Bean and Tea Leaf has a drink they call a Moroccan Mint Latte. It’s a tea latte with chocolate. You can get a fairly good approximation by making hot chocolate using mint tea instead of hot water. Katie suggested Bigelow Plantation Mint (after I mentioned that I’d tried it with Stash Moroccan Mint), which seems to work well.

Update: I forgot to mention the key difference between the two varieties of tea that I tried. Black tea works better with chocolate than green tea.

We have four coffee-house chains in the area, in addition to local places.

My favorite is Diedrich Coffee, with a couple dozen locations in Orange County, two each in LA and San Diego… and three each in Houston and Denver. (In the last few months, Diedrich has started selling T-shirts that say, “Venti, Schmenti.”)

Then there’s Kelly’s Coffee and Fudge Factory, which had about five locations the last time I checked but now has about thirty scattered around Southern California with one more in Lake Havasu… and according to their website, they’re opening one in Riyadh. Yes, Riyadh.

And then there are the international chains. Coffee Bean and Tea Leaf is all over the American Southwest and Southeast Asia. Starbucks, of course, is everywhere.

At one point we had all four chains in one mall. The first phase of the Irvine Spectrum had a Diedrich Coffee attached to the Barnes & Noble, before the bookstore hooked up with Starbucks. The second phase added a Coffee Bean. The third phase added a Kelly’s, and the Barnes & Noble moved to the new section… and added a Starbucks coffee bar inside. Unfortunately the Diedrich’s was off in a corner, and without the bookstore to bring people in, it eventually closed.

Edit: I can’t believe I forgot these, but if you really look for them, you can find Peet’s and Seattle’s Best. Neither has many stores in the area, though.

Forget “Coffee is Hot!” and its variations. What they really need is a warning on iced blended drinks that anything larger than about 12 ounces may separate and require frequent re-mixing unless drunk rapidly. And those are the ones that are mixed well. Let us not speak of the ones you get at the cafĂ© downstairs from the office, or at rush hour when everyone else in town wants a Frappucino NOW and the baristas are just trying to get through with the blenders as fast as they can. You know, the ones that end up like a coffee-flavored snow cone with a straw.

For some reason, coffee just doesn’t seem to blend with ice as well as fruit does.

While cleaning the apartment this weekend, we found a long-forgotten bag of “Lazy Lizard” Mozilla Coffee. RJ Tarpley’s, the company which sold it (and donated a percentage of profits to the Mozilla Foundation) disappeared last summer. By September, I couldn’t even find a whois record. The domain name has since been picked up by a link farm.

It was decent coffee, and it helped support some good software. And I got a nifty mug while they were still in business. There was maybe half a pound left, but 12-month-old decaf coffee just isn’t fit to drink anymore, so instead of brewing one last pot in salute, we tossed what was left.

Maybe it’s the housing costs, but people in San Francisco need a little extra incentive to give out their computer password than people in Liverpool. Last year a survey found that 71% would reveal their password for a chocolate bar. A similar survey this month in San Francisco found that 66% would give it up for a coffee.

At least Verisign made good on the offer—with a $3 Starbucks gift card.

I recently rented two of the Justice League DVDs. So far I’ve gotten through the opening 3-parter, “Secret Origins,” and the 2-part “Paradise Lost.” I have no idea how far into the series the second disc is.

A scene that stuck in my mind was the newly-formed League looking around their headquarters. As the heroes are deciding whether to join, the Flash remarks on its well-stocked kitchen and offers, “Iced mocha?” Wonder Woman tastes one and says, “Mmm, they don’t have anything like this on Themyscira. I’ll stay.” Aha! The way to an Amazon’s heart is through iced mochas!

So it was even more funny in “Paradise Lost” when the Flash started fantasizing about Paradise Island: “The beach, hundreds of women, and me, the first man they’ve seen in, well, ever. And what do I have with me? Iced mochas for everyone!”

Anyway, on to the review: It’s certainly better than I remember Superfriends being. It does still have a significant cheese factor at times, Continue reading
