Background The ale yeast pitching rate generally recommended by commercial brewers is one billion cells, per liter of wort, per degree Plato. Assuming a 25% loss in viability prior to re-pitching results in the rule of thumb of 0.75 billion/L-°P. However, yeast products designed to inoculate at this level are not available on the homebrew […] It probably isn’t necessary to stir Iodophor. OK, so the world probably won’t be beating a path to my door. But there’s a right way to do it, and a wrong way – and a lot of home brewers are doing it the wrong way. The basic idea behind these homebrew stirplates is to […] I was driving around the other day, trying to find a use for all the cranial capacity that goes un-utilized in my day to day life, and I started to wonder if there was some way to quantify some of my wholly unscientific views about Hollywood. Specifically, why some directors it seems can do no […] With all the writing I’ve been doing about yeast lately, I thought it would probably be a good idea to outline my general yeast propagation and storage procedures. There’s an enormous variation, both philosophically and technically, among homebrewers – from directly pitching a smack pack to acid washing and storage in -80°C freezers. My own […] There are many situations in which a homebrewer might need to propagate yeast using more than one step-up – for example, building up from a bottle of commercial beer, or reviving a smack pack that’s several months old. And while I love Mr. Malty’s Pitching Rate Calculator™, doing two-stage starters with it can be frustrating. […] Most homebrewers, once they get seriously involved in the hobby, will make starters for their beers. While the commercial yeast products are advertised as being “pitchable”, their cells counts don’t allow brewers to inoculate a 5-gallon batch of ale at the industry standard rate of about 0.75 billion/L-°P. And the true cell counts may be […] 18 Feb 2010, 23:19 | Tags: booze, helloworld, math, physics, toys | Category: Brewing |

I really don’t know what all the fuss is about graphic design. This was super easy and hardly looks like crap at all. (It’s also an awesome example of your tax dollars at work.) This gag would work a lot better if it was an actual pizza. […] Suck it, everyone who hasn’t lost 10% of their body weight. Being unemployed is pretty much cheating.
Background The pitching rate of yeast is generally accepted to be one of the most important factors in fermentation performance and the resultant beer character. The often quoted “optimal” pitching rate is 0.75 billion cells per liter of wort, per degree Plato for ale, and 1.5 billion/L-°P for lager. However, at the homebrew level, commercial […] Don’t get me wrong, I love SI, but those tend to lack the punch of, say, a Smoot. So, I had to wait 1.8 Freebirds for a treadmill today. I should know better than to go to the gym on a Saturday in January. |
