Last Friday Vinquiry analyzed the latest sample of the Sangiacomo Chardonnay: 1.32 g/L. This suggests 1) astonishingly good reproducibility of the lab analysis, and 2) that the malo has not moved at all in two weeks. The alternative interpretation that the analysis is crap and the ferment is moving by some unknon amount is untenable.
So today I plan to bomb the wine with a huge over-inoculation of bacteria. It's either that, or sulfur the wine and sterile-filter it to bottle when the time comes which is not the goal I had in mind.
