Si todo sale bien, brindamos con vino después del examen.

Yes, salir often means to leave / to go out, but it also has another very common meaning: to turn out.

So todo sale bien literally means everything turns out well.

This is a very natural Spanish expression:

• Si todo sale bien = If everything goes well
• Salió mal = It turned out badly
• Ha salido perfecto = It turned out perfectly

So here sale does not mean physical movement. It means the result is good.

Because after si meaning if, Spanish normally uses the indicative, not the subjunctive, when talking about a real or likely condition.

So:

• Si todo sale bien = correct
• Si todo salga bien = not correct in standard Spanish

A useful rule:

• si + present indicative for real possible situations
• then a present, future, or command in the main clause

Examples:

• Si tengo tiempo, voy.
• Si hace sol, salimos.
• Si todo sale bien, brindamos...

The subjunctive appears in other structures, but not normally directly after si in this kind of sentence.

Spanish often uses the present tense to talk about the future, especially when the future event is seen as planned, expected, or natural from the context.

So:

• Si todo sale bien, brindamos...
  can mean
• If all goes well, we’ll toast...

This is very common in everyday Spanish.

English also does something a bit similar sometimes:

• Tomorrow I leave early instead of
• Tomorrow I will leave early

In Spanish:

• Después del examen, comemos.
• Luego te llamo.
• Mañana voy al médico.

All of these can refer to the future.

Yes. Si todo sale bien, brindaremos con vino después del examen is also correct.

The difference is mostly one of style or nuance:

• brindamos sounds a bit more immediate, conversational, and natural in everyday speech
• brindaremos sounds slightly more explicitly future-oriented or a little more formal

Both are good Spanish.

Because Spanish usually omits subject pronouns when the verb ending already makes the subject clear.

Brindamos already tells you the subject is we:

• brindo = I toast
• brindas = you toast
• brinda = he/she/you toast
• brindamos = we toast

So nosotros brindamos is possible, but normally unnecessary unless you want emphasis or contrast.

For example:

• Nosotros brindamos, pero ellos no.
  = We’re toasting, but they aren’t.

In the original sentence, no emphasis is needed, so just brindamos sounds natural.

Brindar means to make a toast / to toast.

When you say brindar con + drink, you mean to toast with that drink:

• brindar con vino = to toast with wine
• brindar con cava = to toast with cava

So con tells you what you are using to make the toast.

Very often, Spanish also uses brindar por + person/thing to say what or whom you are toasting to / for:

• Brindamos por tu éxito. = We toast to your success.
• Brindo por ti. = I toast to you.

You can even combine them:

• Brindamos por ti con vino.
  = We toast to you with wine.

They answer different questions:

• con vino = with what?
• por... = to what / for what / for whom?

So:

• Brindamos con vino = We toast with wine
• Brindamos por el examen = We toast to the exam / to getting through the exam
• Brindamos por ti = We toast to you

In your sentence, con vino only tells us the drink being used.

Because de + el contracts to del in Spanish.

So:

• de + el = del
• a + el = al

That is why:

• después del examen = after the exam

Compare:

• Voy al cine. = I’m going to the cinema.
• Vengo del trabajo. = I’m coming from work.

One important exception: If el is part of a proper name, you do not contract it:

• de El Escorial
  not
• del Escorial
  when El is officially part of the name

But in el examen, it is just the normal article, so del is required.

Spanish usually uses the definite article more often than English in expressions like this.

So Spanish says:

• después del examen
  literally: after the exam

Even if English might sometimes say after the exam or after exam depending on style, Spanish normally wants the article here.

This is very natural:

• antes de la clase = before class
• después de la cena = after dinner
• durante el verano = during the summer

So del examen is the normal way to say it.

Because here todo means everything, not everyone or all of them.

This todo is a neuter-style form used for general ideas or situations:

• Todo va bien. = Everything is going well.
• Todo está listo. = Everything is ready.

By contrast:

• todos = everyone / all of them
• todas = all of them, feminine

So:

• Si todo sale bien = If everything goes well not
• Si todos salen bien unless you were talking about multiple people or things individually

Yes, it is standard to put a comma when the if-clause comes first.

So:

• Si todo sale bien, brindamos con vino después del examen.

This helps separate the condition from the main statement.

If the order is reversed, Spanish often does not use a comma:

• Brindamos con vino después del examen si todo sale bien.

So the comma here is normal and correct.

Yes, it sounds natural.

It means something like:

• If all goes well, we’ll have a toast with wine after the exam.

A small nuance: brindar specifically means to toast, usually in a celebratory sense. It does not just mean to drink wine casually.

So this sentence suggests:

• the exam is important
• there is a reason to celebrate afterward
• they plan to mark the moment with wine

In Spain, this is perfectly understandable and natural.
