In this video I explain the process for testing to see if the grapes have been affected by the smoke from the recent fires. This entails doing micro-fermentation of grapes the three vineyards that I farm. Next week will send samples off to the lab, where they will test the wine for the presence Guaiacol. If there are more than 5 parts per billion the smoke will be present in the wine. The results will determine whether i harvest this year's crop or drop it on the ground to provide more nutrients for the vines.
