Here 차 means tea, not car.

Korean 차 can mean both:

• tea (茶)
• car (車)

The context makes it clear:

• 달아서 = because it’s sweet
• 마시기 좋아 = good to drink

So this has to be talking about something you drink, which means tea.

는 is the topic marker.

So 이 차는 means something like:

• as for this tea
• this tea, ...

It sets this tea up as the topic of the sentence. In English, we often do not mark the topic this explicitly, but Korean does.

It can also give a slight contrastive feeling depending on context, like:

• This tea, at least, is a little sweet...

But in many everyday sentences, it simply marks the topic naturally.

조금 means a little or a bit.

So 조금 달아서 means:

• because it’s a little sweet
• since it’s slightly sweet

A useful nuance: 조금 often sounds softer and more natural than a direct blunt statement. So instead of saying it is sweet, the speaker says it’s a little sweet, which can sound more conversational and less strong.

달아서 comes from 달다, which means to be sweet.

Breakdown:

• 달다 = to be sweet
• stem: 달-
• -아서 / -어서 = because, so, or a connector linking two clauses

So:

• 달아서 = because it’s sweet / since it’s sweet

In this sentence, it gives the reason for the next part:

• It’s a little sweet, so it’s good to drink instead of coffee.

In Korean grammar, 달다 is usually called a descriptive verb or adjective-like verb.

That means:

• it behaves grammatically a lot like a verb
• but its meaning is adjective-like in English

So although we translate it as sweet, in Korean it conjugates like a verb:

• 달다 = to be sweet
• 달아요 = it is sweet
• 달아서 = because it is sweet

This is very normal in Korean. Many English adjectives correspond to Korean descriptive verbs.

Because 달다 has the stem 달-, and the connector -아서/-어서 is attached to the stem.

Since the final vowel in the stem is ㅏ, Korean uses -아서.

So:

• 달- + 아서 → 달아서

This is the regular form.

대신 means instead of or in place of.

So:

• 커피 대신 = instead of coffee

In this sentence, it means the tea is good to drink as a substitute for coffee.

Examples:

• 밥 대신 빵을 먹었어요. = I ate bread instead of rice.
• 커피 대신 차를 마셔요. = I drink tea instead of coffee.

In this sentence, 대신 is being used as a noun/postposition-like word meaning instead of, so it often comes directly after a noun:

• 커피 대신
• 물 대신
• 버스 대신

That is the natural pattern here.

커피를 대신 by itself would sound incomplete or unnatural in this meaning.

There is also a different expression:

• A를 대신하다 = to replace A / to do something on behalf of A

But that is a different grammar pattern from the one used in your sentence.

마시기 좋아 comes from:

• 마시다 = to drink
• 마시기 = drinking / to drink
• 좋아 = is good

Here -기 turns the verb into a noun-like form. This is called nominalization.

So 마시기 좋아 literally means something like:

• drinking is good
• it is good for drinking
• more naturally: it’s good to drink

In this sentence, the meaning is:

• It’s good to drink instead of coffee.

This pattern is very common:

• 먹기 좋아요 = it’s good to eat
• 읽기 좋아요 = it’s good to read
• 쓰기 좋아요 = it’s good to use/write with

좋아 is the casual, non-polite ending.

Compare:

• 좋다 = dictionary form
• 좋아 = casual speech
• 좋아요 = polite speech

So the sentence is in a casual style:

• 이 차는 조금 달아서 커피 대신 마시기 좋아.

If you wanted to say the same thing politely, you could say:

• 이 차는 조금 달아서 커피 대신 마시기 좋아요.

So this is mainly a matter of speech level, not meaning.

Yes, the person is not explicitly stated, and that is very normal in Korean.

The sentence does not specifically say:

• I
• you
• people
• one

Instead, Korean leaves it understood from context.

So the sentence can mean something like:

• This tea is a little sweet, so it’s good to drink instead of coffee.
• This tea is nice as a substitute for coffee.

It sounds like a general statement rather than focusing on a specific person.

It can feel like both.

The connector -아서 / -어서 often links two ideas in a cause-result way:

• because X, Y
• X, so Y

So here:

• 조금 달아서 커피 대신 마시기 좋아 can be understood as:
• Because it’s a little sweet, it’s good to drink instead of coffee or
• It’s a little sweet, so it’s good to drink instead of coffee

In natural English, so often sounds smoother, but the Korean grammar itself expresses the reason/result link.

Yes, that is the basic idea.

The logic is:

• this tea is a little sweet
• because of that, it works well instead of coffee

The implied nuance is something like:

• it may satisfy you in a similar way
• it may feel pleasant without needing coffee
• the slight sweetness makes it appealing as an alternative drink

So the sentence is not just describing the tea; it is also giving a reason why it is a good replacement for coffee.

It can mean either, depending on context.

In many cases, V-기 좋다 can suggest:

• good to V
• nice to V
• easy/pleasant to V

So 마시기 좋다 could mean:

• good to drink
• pleasant to drink
• easy to drink

In this sentence, the most natural interpretation is:

• good to drink instead of coffee or
• nice as a drink instead of coffee

The exact English wording can vary a little, but the Korean meaning is basically about suitability and pleasantness.
