Personally, I am envisioning this lab that would have the equipment needed to numerically quantify parameters that may feed into not only the perception of consistency but the measurement of it. This would be things like VDK levels, various hopping things, abv, dextrins/gravity/calories, etc. Short of having a mass spec, which are admittedly becoming pretty cheap these days, but also having access to all of the needed test protocols and reagents AND having a gas chromatograph, I can't see how a brewery who doesn't have the coin for a more automated brewhouse which has real, measurable impact on production would spend the money on instruments that, no doubt have impact on production and sales, but definitely not the way a new brewhouse or two more fermenters would have.
