我喜欢酒很多。is grammatically incorrect. It makes no sense. 我喜欢的酒很多。is correct. The 的 is necessary. Note: Though 的 is optional in many cases, you cannot omit it when a verb or a noun+verb modifies a noun. In your sentence, 我喜欢(noun/pronoun + verb) is modifying the noun 酒, so a 的 must come between them.

“我喜欢酒很多”means you like much wine. “我喜欢的酒很多”means you like various wine.

Meixing: the frist sentence is not correct,as a chinese,I can't understand what you say.mybe you can change like this ： 我喜欢喝的酒很多。 我喜欢喝很多的酒。 actually the second sentence is right,but you want to find the difference between these sentence,so you must change.
