How do you say ”くせがある” in English?

Hi. Could I ask you a question? It is a little thing*.

I went to a new Bali-style cafe near my house the other day, it was the Bali style. I tried to order a Balinese** coffee, and I asked the owner who took my order "I'd like to try this Balinese coffee, but I have never drunk*** yet had it. What kind of tastes does it taste like?"
She said "すこしくせがあります".
”くせがある”　is very popular pharase phrase in Japan, it is used for someone's personality or food's taste or someone's writing character**** and so on. I suppose that "くせがある" means something strange and not ordinary.
In this case, what is the best phrase in English? If you have any ideas, please tell me. Thank you.

バリコーヒーは、どうでしたか？教えて下さい。

I think くせがある could be translated as "unique" (ユーニク) in most cases. "Idiosyncratic" is also good.　But there are many other good expressions, like "one of a kind" or "in a league of its own." ("Balinese coffee is one of a kind," "Saki-san is in a league of her own," etc.)  

* It is a little thing" - There are a couple of good ways to say this in English. Both are good phrases, and will help your English sound very natural. The first is "It's just a trivial matter" or "It's just a trivial thing." (This is a formal expression). The other expression is very informal, and very common: "It's no big deal." (The grammar of the second one is wrong, but everybody uses it anyhow. It is a really good informal way to say that something is small and not very important - but you want to know anyway) By the way, a very informal way to say this is "No biggy."

** "Balinese" might be too fancy. "Bali-style" would work too.

*** You can't use "drunk" this way. The past-tense form is "drank." ("Drunk" means 酔っ払う or 酔っ払い depending on how it is used).

**** "Someone's writing character" - It's not clear what you mean. Is it author's writing style (著者のスタイル／風格) or characters in a story (fictional characters - 小説の人物)?

Hi. Could I ask you a question? It is a little thing.

I went to a new cafe near my house the other day, it's decor and food was in the Bali (Balinese) style. I tried to order (wanted to try) a Bali (Balinese) coffee, and I asked the owner who took my order, "I'd like to TRY this Bali (Balinese) coffee, but I have never drunk yet (drank it before). What kind of tastes?" (How does it taste? What does it taste like?)
She said "すこしくせがあります".

Hmmm....my Japanese is way beyond "rusty," but in English (which of mine is "rusty" also!) it lends itself towards "peculiar" or "quirky" or, I would even go so far as to say "perverted," and has a somewhat negative connotation. Now, whether the owner was referring to you or your tastes is another question, but I hope that you enjoyed the coffee! I hope this helps you. J.
