It's taste bitter to me, but I love the smell.

When I was younger, iI didn't like tea too, because I tried it with sugar.

But I preferred it without sugar, just natural.

I like tea with mint too.

It's a tea from mMaghreb and m. My grandmother was aAlgerian, so she prepared us a lot.

In reality, I prefer herbal tea like rooïbos, chamomille, lemon, or some mix.

I love to drink it before go to bed, with a good book.

And iIn the morning, I prefer to drink a hot chocolate, because I stay a childam childlike in some sense.

Hot chocolate can also be for grownups, but I know what you mean.

It's mMy conmfort drink, my is "mMadeleine de pProust".

I don't think we have something similar in English. Thanks for helping me learn a new French expression.

It's tastes bitter to me, but I love the smell.

There is no need for 's in, just "it" is correct because when we talk about an object's quality, we don't generally use apostrophes. For example, "It was a beautiful ship. Its sails were huge."

Also, the verb to taste is usually conjugated with an "s" at the end.

When I was younger, i didn't like tea too,I didn't like tea when I was younger because I tried it with sugar.

No need for too many commas here.
Also, there is no reason to say "too" because you are not agreeing to some person's or group's opinion. Additionally, sometimes "too" is replaced by "as well" in formal writing.

It's my conmfort drink, my "madeleine de proust"

When someone does something to another thing, "s" is sometimes added. For example, "He makes me whole."
