A $7 iPhone App?!?!

Although I probably won't be adding any critical chemicals or yeast to the fermentation tanks (that's the winemaker's job), it wouldn't hurt to know exactly how it's done.  That's why I downloaded an application called Cellar Hand to my iPhone.  Price tag: $6.99.

Flashbacks of Chem 101 and 102 and lengthy unit conversions made paying $7 a little more palatable.  Besides, if NASA can crash a $300-million probe into Mars just because some Ph.D. couldn't get the conversion to meters just right, it's quite possible that I'll screw something up and turn a tasty tank of syrah into a yeasty, sulfurous mess of vinegary swill.

Um, how many hectoliters in Tank #3?
