This is something I’ve been meaning to do for a long time, but kept finding excuses to put off. It uses the simplified cubic polynomial derived in Refractometer FG Results. Please visit that post for more information. Original RI (°Bx): Final RI (°Bx): Wort correction factor: (Default: 1.040) If you don’t have a subscription, you might want to pick up the May/June issue, which should be hitting newsstands right about now. And maybe let them know which article interested you?
How weird is it that I’m considering framing this?
A refractometer is one of the most useful tools a brewer can have. 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 [...] 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 scale. [...] Suffice it to say that I’m not so wild about religion. I have nothing against funny hats, and some of the music is very nice; it’s just that blind adherence gives me the willies. I fully acknowledge a continuum of harm, but psychologically, chemically speaking, there’s no difference between getting up earlier than you want [...] Why does Apple only stand up and say, “this is what we’re doing, and this is why” every year or two? When they do, it usually makes the hairs on the back of my neck stand up. Thoughts on Flash Flash was created during the PC era – for PCs and mice. Flash is a successful business [...]
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 the [...] 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 [...]
Three of the four words on this tag are lies. On my recent trip to New Orleans, given that I was only traveling for four days, and not a women, I only needed to pack one bag. I elected to take only a carry-on – an easy decision given that checking luggage costs one-fourth as [...] (Or: How I Stopped Worrying and Learned to Love the Filibuster)
Apparently Republicans are sore losers. First of all, it irks me a little every time a talking head uses the phrase “health care reform”. As Americans, we have the best health care in human history, and almost all of it at even the smallest hospital [...] |
