想请问一下，这段文章中的staright-up查过字典是
used to show that you are telling the truth 真的，属实。
但后面的Stella不是人名吗，为什么会加入Stella呢?
Part of the brewers' interest stems from boozeless beer's frothy margins.
Making the stuff is actually more expensive than making a straight-up Stella.
The process usually involves taking a finished alcoholic beer and stripping
away the booze (brands guard their methods closely)
谢谢
