Developing grapevine leaves are harvested for the preparation of stuffed dolmas. Fresh leaves are preferred, but since they are perishable and can be harvested at ideal maturity for only a limited period, most leaves for dolmas are currently preserved. This research on fresh grapevine leaves (var. Thompson Seedless) was conducted over three seasons, and focused on their postharvest performance in relation to leaf maturity, respiration rates, storage temperature, water loss and packaging, and decay control. Appropriate leaf maturity for dolmas are leaves that are bright green and not yet fully expanded. The 4 leaf maturity stages that can be harvested commercially for dolmas are clearly delineated by differences in color, and corresponding color values and pigment concentrations. Sugar, acid, and phenolic concentrations and % dry weight vary little among the 4 maturity stages studied. Respiration rates of grapevine leaves (mature for dolmas) are moderate, about 350 µmol CO₂ kg⁻¹ h ^− 1 at 5 °C. Grapevine leaves can be stored for 4–8 weeks at 0 °C. A storage period of 1 month can be expected if they are stored in the range of 0–5 °C. Grapevine leaves can be stored below 0 °C but freezing injury occurs near -2.5 °C. Water loss at 8–10% is needed to reduce marketable quality (loss of gloss, leaf curling, browning). Botrytis decay is the major limitation to storage life and decay incidence varied from harvest to harvest. Decay is partially retarded by high CO₂ atmospheres (10–15% v/v), but is more effectively controlled by hot water dips of 47.5 °C to 52 °C (15 to 9 min). Grapevine leaves harvested for dolmas do not show yellowing during aging or senescence when held below 10 °C.

收获正在发育的葡萄叶用于制备填充的 dolmas。新鲜的叶子是首选，但由于它们容易腐烂并且只能在有限的时间内在理想的成熟期收获，因此目前大多数用于 dolmas 的叶子都被保存了下来。这项关于新鲜葡萄叶 (var. Thompson Seedless) 的研究进行了三个季节，重点关注与叶成熟度、呼吸速率、储存温度、失水和包装以及腐烂控制相关的收获后性能。适合 dolmas 的叶子成熟度是鲜绿色且尚未完全展开的叶子。可商业收获的 dolmas 的 4 个叶子成熟阶段通过颜色的差异、相应的颜色值和色素浓度清楚地划分出来。糖、酸、在所研究的 4 个成熟阶段中，酚类浓度和干重百分比几乎没有变化。葡萄叶（杜尔马斯成熟）的呼吸速率适中，约 350 µmol CO₂ kg ^-1 h  ^{-  1}在 5 °C。葡萄叶可以在 0 °C 下储存 4-8 周。如果将它们储存在 0–5 °C 的范围内，则可以预期储存期为 1 个月。葡萄叶可在 0 °C 以下保存，但在 -2.5 °C 附近会发生冻害。需要损失 8-10% 的水分才能降低适销性（失去光泽、卷叶、褐变）。Botrytis 腐烂是贮藏寿命的主要限制，腐烂发生率因收获而异。高 CO ₂气氛 (10–15% v/v)可部分延缓衰变，但 47.5 °C 至 52 °C（15 至 9 分钟）的热水浸渍可以更有效地控制衰变。当温度低于 10 °C 时，为 dolmas 收获的葡萄叶在老化或衰老过程中不会变黄。
