===Harvest===
Harvesting vanilla fruits is as labor-intensive as pollinating the blossoms. Immature, dark green pods are not harvested. Pale yellow discoloration that commences at the distal end of the fruits is not a good indication of the maturity of pods. Each fruit ripens at its own time, requiring a daily harvest. "Current methods for determining the maturity of vanilla (''Vanilla planifolia'' Andrews) beans are unreliable. Yellowing at the blossom end, the current index, occurs before beans accumulate maximum [[glucovanillin]] concentrations. Beans left on the vine until they turn brown have higher glucovanillin concentrations but may split and have low quality. Judging bean maturity is difficult as they reach full size soon after pollination. Glucovanillin accumulates from 20 weeks, maximum about 40 weeks after pollination. Mature green beans have 20% dry matter but less than 2% glucovanillin."<ref>{{cite journal|title=Determining the harvest maturity of vanilla beans|author1=S. Van Dyk |author2=P. Holford |author3=P.

To ensure the finest flavor from every fruit, each individual pod must be picked by hand just as it begins to split on the end. Overmatured fruits are likely to split, causing a reduction in market value. Its commercial value is fixed based on the length and appearance of the pod.

If the fruit is more than {{convert|15|cm|in|abbr=on}} in length, it is categorized as first-quality. The largest fruits greater than {{convert|16|cm|in|abbr=on}} and up to as much as {{convert|21|cm|in|abbr=on}} are usually reserved for the gourmet vanilla market, for sale to top chefs and restaurants. If the fruits are between 10 and 15&nbsp;cm long, pods are in the second-quality category, and fruits less than {{convert|10|cm|in|abbr=on}} in length are in the third-quality category. Each fruit contains thousands of tiny black vanilla seeds. Vanilla fruit yield depends on the care and management given to the hanging and fruiting vines. Any practice directed to stimulate [[aerial root]] production has a direct effect on vine productivity. A five-year-old vine can produce between {{convert|1.5|and|3|kg|lb|abbr=on}} of pods, and this production can increase up to {{convert|6|kg|lb|abbr=on}} after a few years. The harvested green fruit can be commercialized as such or cured to get a better market price.<ref name="Anilkumar 2004"/><ref name="Davis-1983"/><ref name="Elizabeth 2002"/>
