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 […]

As a quick follow-up to my starter aeration experiments, I made up a DME starter for comparison purposes. As would be expected, it produced substantially more yeast than the sugar starters. So if nothing else, don’t take the cell counts estimated in the original tests to be accurate for beer – something I probably should […] This is either insightful or dumb, depending on your state of mind. Either way, it’s hilarious, and the kind of thing Dan Brown would write if he had a working adult vocabulary. […] 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 […] If a rock is dropped from a sea cliff, and the sound of it striking the ocean is heard 3.2 seconds later and the speed of sound is 340 m/s, how high is the cliff? No need to show your work, but time yourself. It seems like a question that would totally be worth answering […] … but what to do with it? I spend a fair amount of time trolling the Northern Brewer forums, and one of the more frequent exchanges goes something like: Q: OK, I have my water report, now what do I do with it? A: Read chapter 15 of How to Brew and come back if […] I’m getting ready to rack Batch 25 into a (long, long) secondary, on top of some Jim Beam Rye (Michael Jackson gave it 8/10!) and some oak chips. I’ve toasted oak for a few brews before; this time, I wanted a nice dark toast to pair with the rye and the residual sugars, so I […] Today’s forecast high for Lafayette was 12°C. The actual high was 17°C. I actually know a thing or two about the difficulties inherent in modeling complex non-linear systems, but given the amount of resources we’ve invested in this particular problem over the past half-century or so, we should be able to do a lot better. […] “I keep trying to make that a chainsaw, but it stays a duck-billed platypus.” I definitely feel like I can tell what is real, but it’s much harder to identify what real element is causing them to be distorted in my brain, and how. Ex: a SAM appeared to be chasing a plane, but I […] OK, so I had some really weird dreams Wednesday night. I guess they could actually be normal dreams for me, it’s just that I almost never remember my dreams, so remembering three in the same night is off the charts. The first one is that I was on Jeopardy! and after the first round all […] |
