A stir plate (a.k.a magnetic stirrer) is a device used by homebrewers to increase yeast cell count when making a yeast starter. It’s essentially a magnet(s) attached to a fan, which is then controlled by an IC voltage regulator. Construction is relatively inexpensive (mine cost about ¥5000 in parts), rather fun, and takes less than an afternoon to complete.

There are literally hundreds of websites and video tutorials that show how to build a stir plate, so I’ll spare you the details and offer you pictures instead.

My first experience with homebrewing was back in Los Angeles in the early 1990s. I was meeting up with mates just before heading out to a Björk concert. While waiting to leave, the owner of the apartment, a guy called James, offered me a beer: “This is my brew,” he said, and then proceeded to show me a boxful of bottles tucked away in his closet.

James’ beer hadn’t been particularly remarkable, but it left me with an inexplicable aftertaste of personal envy (and so it was then that the homebrewer’s seed was unwittingly planted, buried deep within me). Over the years I’d see beer making kits for sale, but always resisted purchasing one somehow insisting “real” beer couldn’t possibly be made that way.

Fast-forward to spring 2010, at the apartment of my colleague, Neil. I’d just finished a four-day beer making seminar; Neil invited me over to watch him brew. Pots and pans and silicone tubes littered his kitchen as I gawked impressed by how uncomplicated making beer appeared to be. I took copious notes, encouraging myself to give it a go.

Fast-forward nearly exactly one year and a number of brews later, and I’ve since become an undeniable homebrew maniac. In a few hours I’ll be at Tokyu Hands, shopping for yet more pots and pans and silicone tubes of my own. Yesterday, I spent the day back at Neil’s place, again to watch his brewing process and talk beer. I learned more about carbonating kegs, stir plates and refractometers, and Neil introduced me to force fermenting yeast starters. I took pictures (and more copious notes) as he walked me through his latest Blonde Ale-Kölsch hybrid boil.

And so here he is, my Obeer-Wan Kenobie, the bloke who kicked my ass into homebrewer gear.

It’s Tuesday morning, the temperature outside a lovely 19.5°C. And I’m inside staring at the calendar in a mild state of shock and awkward panic: only 53 days in 2010. Oh. My. Godzilla.

I’m not sure about you, but that doesn’t seem enough time to get done all things upcoming (and still haven’t done) I so desperately need to do. So I’m making a list and checking it twice – nay, thrice – in a shaky attempt to feel productive.

Tomorrow, Wednesday, the 10th: Dentist! 2/6 visit. Also, order some lager yeast and a new bottling wand. Don’t forget to visit the bank, post office, and Tokyu Hands, too.

Sunday, the 14th: Bottle 20L of my Nut Brown Ale v2.5, then off to Nakameguro Taproom’s “Falling for Brew” event. Afterward, dinner with the wife in Chinatown, Yokohama.

Wednesday, the 17th: Brew 20L of Export Pilsner. Decide whether or not I can attend the Japan Beer Times “Dachambeer” event. Dinner with Family, Inc.

Sunday, the 21st: Personal deadline for 年賀状 (Nengajō, Japanese New Years cards). Must. Get. Them. Finished! Ack! Wife’s birthday in less than two weeks! Have to buy tickets for the Ghibli Museum ! (She’d better not be reading this!)

One-month countdown to Switzerland: So much shopping for Winter wear yet undone, as well as double-checking lists of magic shops and breweries I plan to visit. Am I forgetting something? Probably. What!?

Birthdays, check. Medical insurance premiums, check. What is it I’m forgetting?

Only a week left in November; hulloa boys, hulloa boys, better remember!
