The marketing value of table grapes is contingent upon several quality requirements, mostly related to microbial decay, sugar/acidity ratio, and colour. This research explores the impact of combining organic-cultured compatible techniques to delay disorders along with organic grape distribution in post-harvest. <i>Aurebasidum pullulans</i> in-field application on grape bunches at three growing stages as a biocontrol agent against grey mould growth coupled with massive modified atmosphere packaging (MMAP; 20% CO<sub>2</sub>, 10% O<sub>2</sub>) equipped with a breathable valve was tested. The in-field treatment had a significant impact on the colour and sugar content of the grapes at harvest and the mould count evolution during storage, whilst the trend of the other parameters was mainly affected by the interaction of the variables tested. The untreated batch experienced the worst behaviour and the packaging was paramount in preserving the moisture content and appearance of the bunches. The findings of this study may contribute to developing novel practices for setting a smart distribution of organic table grapes and reducing food waste.
