Je trouve que ce café est mauvais.

Yes. Je trouve que literally means I find that, but in everyday French it often works like I think that / I feel that / I find that in English.

So:

• Je trouve que ce café est mauvais = I find this coffee bad / I think this coffee is bad

It is a very natural way to give a personal opinion.

Compared with similar phrases:

• Je pense que = I think that
• Je trouve que = more like I find / I feel / in my opinion, from my experience

With food, drink, films, places, etc., je trouve que is extremely common.

Because café is a masculine singular noun and it begins with a consonant sound.

French uses:

• ce before a masculine singular noun starting with a consonant
• cet before a masculine singular noun starting with a vowel or silent h
• cette before a feminine singular noun

So:

• ce café = correct
• cet ami = correct
• cette table = correct

Since café is masculine and starts with c, you use ce.

It can mean either, depending on context.

• un café can mean a coffee
• un café can also mean a café / coffee shop

In this sentence, because of est mauvais, the most natural meaning is this coffee is bad.

If you were talking about a coffee shop, the sentence would usually need context to make that clear:

• Je trouve que ce café est mauvais could technically mean I think this café is bad, but without context many learners will understand it as this coffee is bad.

Because mauvais is an adjective, and in French adjectives usually agree with the noun they describe.

Here, the noun is:

• ce café

And café is masculine singular, so the adjective must also be masculine singular:

• mauvais = masculine singular
• mauvaise = feminine singular

Examples:

• Ce café est mauvais.
• Cette soupe est mauvaise.

So the form changes to match the gender of the noun.

Que here means that and introduces a clause.

Structure:

• Je trouve = I find / I think
• que = that
• ce café est mauvais = this coffee is bad

So the full structure is:

• Je trouve que + clause

In English, we often drop that:

• I think this coffee is bad

But in French, que is normally required after expressions like je trouve, je pense, je crois, etc., when another full clause follows.

Both can exist, but they are not exactly the same.

• Ce café est mauvais = This coffee is bad
  
  • You are directly talking about this coffee
• C’est mauvais = It’s bad / That’s bad
  
  • More general, less specific, or used after identifying something

In your sentence, ce café is the subject, so est follows it directly:

• ce café est mauvais

You do not normally say:

• ce café c’est mauvais in this simple structure

So ce café est mauvais is the standard form here.

Yes, a French speaker could definitely say it, but mauvais can sound fairly direct.

It means:

• bad
• poor
• not good

For coffee, it sounds natural, but depending on tone it may be blunt. Softer alternatives include:

• Ce café n’est pas bon. = This coffee isn’t good.
• Je trouve que ce café n’est pas terrible. = I think this coffee isn’t great.
• Je trouve que ce café est médiocre. = I think this coffee is mediocre.

So mauvais is correct and natural, but not the only choice.

Yes, in many situations you can, but the nuance changes slightly.

• Je pense que ce café est mauvais. = I think this coffee is bad.
• Je trouve que ce café est mauvais. = I find this coffee bad / I think this coffee is bad.

A simple way to feel the difference:

• je pense que = more about what you think
• je trouve que = more about your personal impression or judgment

With taste, quality, and opinions based on experience, je trouve que often sounds especially natural.

A careful pronunciation is roughly:

zhuh troov kuh suh ka-fay ay mo-vay

A few useful notes:

• Je sounds like zhuh
• trouve sounds like troov
• que is usually a short kuh
• ce sounds like suh
• café = ka-fay
• est is pronounced ay
• mauvais sounds like mo-vay

In normal speech, French flows smoothly, so the sentence may sound more connected than the spelling suggests.

The sentence follows this pattern:

• Subject + verb + que + subject + verb + adjective

Broken down:

• Je = subject
• trouve = verb
• que = linking word introducing a clause
• ce café = subject of the second clause
• est = verb
• mauvais = adjective

So literally:

• I find that this coffee is bad

This is a very useful model you can reuse:

• Je trouve que ce film est intéressant.
• Je trouve que cette chanson est belle.
• Je trouve que ton idée est bonne.
