The research suggested that American white oak is the best choice for the production of grape wine with strong oak aroma and European oak is the best choice for the production of grape wine with harmonious oak aroma, fruit aroma and wine aroma; air drying process of barrel plates would influence the content of total phenol, tannin and volatile substances including vanillin and MOL; and baking intensity will change original content of chemical compositions in oak and make oak barrel possess different aroma characteristics and phenol substance content.

研究表明，酿制橡木香较浓郁的葡萄酒选用美国白栎较好，酿造像木香、果香、酒香协调的葡萄酒则选择欧洲橡木较适宜；板材风干过程对橡木板材中的总酚、单宁含量及挥发性香气物质香兰素和橡木内酯的含量均有影响；烘烤强度可改变橡木木材原有的化学组分含量，使橡木桶具有不同的呈香特性和酚类物质含量。
