Does that make sense? For a 1.054 lager with a stir plate it calls for 7 vials of White Labs per 3.5 quart starter. WOW.The pitfalls of Mr Malty. We as homebrewers have under pitched our liquid yeast for years. Amazingly enough, we still made great award winning beer and nudged the craft beer industry in a positive direction; all without Mr. Malty showing us the way.
I only have a 2000ml flask.
Is that right 7 vials at $7 each.
Ancient proverb states that a brewer with just one thermometer always knows his temperatures, whereas a brewer with 2 or more never does.I bought a NIST traceable partial immersion lab thermometer from Cynmar to calibrate two dial thermometers, two Ranco probes and my hand held digital. Interesting enough, my family of thermometers were between 7 and 8 Deg F off (high). I did the ice bath and boiling point tests on the new one and got 34 and 221 F respectively. They sent me a another one and it registered 35 and 222 F! My brand new Thermapen is stable in the ice bath at 32.1F, so I'm now back to just one and finally happy.
At mash temperature my NIST certified glass thermometer reads 7 to 8 degrees F below two Ranco probes, two dial Blickman thermometers, one handheld dial thermometer, and one nice digital model. Just to confuse the matter, I checked it against a glass NIST calibrated (cheap) lab thermometer, and it is all over the place. I need to do the calibration thing as well.Did the ASTM ice bath calibration on the "good certified" thermometer and it reads 35.5F. The cheap one reads almost right on. The good news is Cynmar is shipping a new "good certified" one. Since both of these are partial immersion, I made sure I used the immersion mark for the test.
Taks a look at what it costs to develop 4-6 Kw of solar power.
