本文采用福林丹尼斯法测定成熟期西拉、品丽珠、美乐、赤霞珠和黑比诺5个酿酒葡萄品种种子单宁的含量和品质，并结合感官品评对浸提液浓度、浸提时间和温度等条件进行优化。结果表明：浸提液浓度为12％、温度28～29℃、8～10d时浸提效果较好。不同品种种子单宁含量和品质差别较大，其中黑比诺种子浸提出的单宁是西拉的两倍，按照提取单宁含量排序为：黑比诺〉美乐〉品丽珠〉赤霞珠〉西拉。
本文採用福林丹尼斯法測定成熟期西拉、品麗珠、美樂、赤霞珠和黑比諾5箇釀酒葡萄品種種子單寧的含量和品質，併結閤感官品評對浸提液濃度、浸提時間和溫度等條件進行優化。結果錶明：浸提液濃度為12％、溫度28～29℃、8～10d時浸提效果較好。不同品種種子單寧含量和品質差彆較大，其中黑比諾種子浸提齣的單寧是西拉的兩倍，按照提取單寧含量排序為：黑比諾〉美樂〉品麗珠〉赤霞珠〉西拉。

Folin Denis method was used to detemine the contents and quality of tannins in seeds of Syrah, Cabernet Franc, Merlot, Cabernet Sauvignon and Pinot Noir ripe grapes. Sensory evaluation was also employed to determine the optimal extraction concentration, time, and temperature. Results showed that 12% extract concentration, temperature of 28- 29 ℃ and 8- 10 days＇ extract time gave the best results. Tannin content and quality in seeds from different varieties varied greatly. The content of tannin in Pinot Noir was twice that of Syrah. The extracted tannin content in these varieties were in the following order： Pinot Noir〉 Merlot〉 Cabernet Franc〉 Cabernet Sauvignon〉 Syrah.
