The name of this Asahi low malt beer (happoshu) is Style Free. In English this sounds like the product completely lacks style - not good. But in Japanese has taken the word free in the sense that you are freed from restraints. So when you see gloves that say "size free" it means "one size fits all". Therefore, "style free" means "drink this beer in any situation and don't be constrained by a certain style or occasion".
The English which follows "refreshing new style" could be doublingly confounding it you do not keep in mind that they are trying to stay something like "a new style which is free of the constrains of any specific style". My wording here is less than eloquent, but hopefully you get the idea.
