They were made out of stocks of rye grass and sometimes they fell apart in your julep.

它们是用黑麦草做成的，有时它们会在你的酒中散开。

20 years ago they made a decision to change the grass or they changed it to some type of rye grass, I don't know why that's thicker, I don't know why the bounce is truer.

20 年前，他们决定换草，或者换成某种黑麦草，我不知道为什么它更厚，我不知道为什么反弹更有力。
