Batch Sparging Calculator

Like many brewers, I use recipe software (BeerTools Pro in my case) to design recipes, log notes, track inventory, etc. And I really like it; the only thing it won’t do is estimate my efficiency based on the actual mash parameters. Hence this little tool, which does exactly that (and pretty much only that). For [...]

Things I Hate #152: Wine

Well, maybe “hate”‘s a strong word. I’ve just never had a wine that I’d prefer over a good beer. I’ll keep trying though. You know, for science.

What I do hate is the wine industry. Bunch of namby-pamby grape gropers whose bottles collect dust and who spit instead of swallow. Which is why my interest [...]

Refractometer Calculator

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. You can also download a spreadsheet to track OG, FG, and more for multiple batches.

Original RI (°Bx): [...]

Zymurgy

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?

 

Refractometer Estimates of Final Gravity

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 [...]

Yeast Pitching Rate Results

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 [...]

Science: It Works, Bitches

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 [...]

Way to Go, Steve-o

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 [...]

Build a Better Stirplate

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 [...]

Yeast Ranching and You

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 [...]
