Last month I posted a brief summary of the troubles I was having with the de facto standard refractometer correlation for final gravity. Specifically, I found that it under-estimates FGs by, on average, about five “points”. More interesting, or at least more useful, I also found that the degree of the discrepancy is fairly well [...]

That’s how many batches I’ve brewed (since I started keeping notes). A question about preferred OG ranges came up in an NB forum topic, and I couldn’t decide if I liked 1.050-1.059, or 1.060-1.069. Turns out the answer is a little of both: the mean is 1.065 (with a standard deviation of 0.029 – outliers [...] What’s the point of having GPS on your iPhone if you aren’t going to geek out about stuff?

It allows for near-instantaneous measurements of specific gravity, without having to compensate for or adjust sample temperature or withdraw a large volume of wort/beer (a significant concern at homebrew scales). There are a few issues associated with accurately using a refractometer for [...] It’s spring cleaning time in the brewery. I’ve given the kegerator a good once-over, scrubbed the kettles shiny, replaced all the vinyl tubing, and so now it must be time for instrument calibrations. I check the hydrometer and refractometer every few batches because it’s so easy (use water and a 10% sucrose solution), but it [...] One year ago today, I decided I didn’t really want to be fat anymore, and was going to lose 35 pounds in the next year. I didn’t quite make it, but I can say that I’m probably in better shape now than at any time since that last high school water polo game. I seriously [...] 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 control [...] 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 [...] |
