This is probably doable, if the market was large enough to merit the investment.
There is a lot of interest in the authenticity of high-value alcoholic drinks, and this has led to development of various methods for analysing their composition quickly and easily - the same techniques could be fairly readily adapted to look for particular levels of various compounds and compare these against a reference database to decide when it's "ready", and it'd probably be fairly simple to define a profile for your own particular preferences.
Something like this linked up to a partner app would do pretty much what you're looking for: http://www.perkinelmer.co.uk/product/torion-t-9-portable-gc-ms-instrument-ntsst090500
"Portable" is relative of course ;)
