A good soup?

[bonia]

Is it correct to say: I am tasting A good soup? 'Soup' is uncountable ; is there any speacial meaning by 'good'?

[Scratch]

a soup - разновидность супа (щи, борщ ...)

[Erica Blair]

I am tasting A good soup

Regardless of articles, your sentence is odd.

[bonia]

I was asking about the article'a' with the adjective'good'plus an uncountble noun. Does the article give the possibility to take 'a' in such a case?

[Scratch]

"a" goes with "good" only if the uncountable noun is  a b s t a r c t :
to have a good time
but "good weather"

[Erica Blair]

"a" goes with "good" only if the uncountable noun is  a b s t a r c t :
to have a good time

Sorry, you are wrong.
It's possible to say It's a good soap, meaning a good kind of soap. Why not have the same with soup?

Articles with non-count nouns are tricky.
There’s a superb source on grammar:

So, the truth is over there...again. It's simple when used automatically but just stop and think a bit more and, oops, what is  to be chosen? And explained?!

[Erica Blair]

You've got evrth explained. Have you not?

[Scratch]

Sorry, you are wrong.

А в чём я wrong?

[bonia]

Well, well... I have found another example:  ' My Granny makes a very fine jam. She makes four jams every year.'    So, again, why my first example is odd? As we can see 'uncountble can become countble' and it will depend on what I mean only- a kind of soup or food itself. Two teachers ( one is American, the other is English) disagree whether "soup' is countable or not.  So I have found the way by myself-thanks everybody. Will I be right or wrong depends on me? I am grown-up , I will get through. What about poor pupils at schools? What do teachers  tell them what is right or wrong? Teachers , please...

But I quoted the piece I disagree with. Soup, soap and the like are not abstract, they are mass nouns, still they can follow a good.
Remember that the basis of a good soup is a strong stock.
"If a woman's wearing a good perfume, that's all she needs to wear,"
Bonia, it's very simple. I have to repeat myself:
When we mean a kind of most mass and even abstract nouns can have the indefinite article.
The comfort of eating a thick [kind of] soup is widely extolled.

[bonia]

Then why my first sentence was ODD?

[Scratch]

to Erica Blair - Do you really disagree with what I mentioned right after the subject was raised?

[ibelk]

Then why my first sentence was ODD?

To tell the truth, that sentence seemed to be a little odd to me, too.
When you are tasting something, you are not supposed to know beforehand how it tastes, it's the goal of your tasting to ascertain its qualities.
But a phrase like this would seem quite natural to me:
I am tasting the soup that is said to be good.

[Erica Blair]

to Erica Blair - Do you really disagree with what I mentioned right after the subject was raised?

It's much simpler to talk if you present the issue in the same post with your question - as a quotation.
Scratch, you gave Bonia a good explanation at once. In fact I only repeated what you’d said.

Then why my first sentence was ODD?

Because it is odd even in Russian.
Как говорится, надо "притягивать за уши" ситуацию, в которой можно сказать Я пробую хороший суп. 

Этот момент очень немаловажный. Ситуация типичная: если надо придумать предложение, учащиеся сразу придумывают на английском. Грамматически оно правильное, а по смыслу нелепое или почти нелепое. Почему так происходит? Потому что активный английский пока еще очень ограничен.
Надо лучше сначала придумать на родном языке. Или хотя бы осмыслить свое английское предложение.

Дело в том, что это пример из учебника, а не мое изобретение...Тогда не было бы вопроса, наверное.

[ibelk]

Дело в том, что это пример из учебника

Действительно, в словаре Collins есть такое значение:
taste = an archaic word for "enjoy"
Т.е. I am tasting a good soup. = I am enjoying a good soup. (?)
Другие значения по смыслу совсем не подходят. 

[Scratch]

А ещё мы забыли о глаголе "дегустировать". По-моему, неплохо смотрится.

Назовите, пожалуйста, учебник и страницу.

ibelk,
Можно разбирать что-то архаичное из книг. А какой смысл это ставить в учебник?

А ещё мы забыли о глаголе "дегустировать". По-моему, неплохо смотрится

А по-моему, плохо. Чем же дегустировать отличается от пробовать?
Вот стоят 5 кастрюль с хорошими супами и 5 с плохими. Я дегустирую один их хороших. И почему-то сообщаю об этой процедуре незнакомому с супом слушателю.

[Scratch]

А мне, дегустатору, жена по телефону в этот момент звонит и спрашивает, чем, мол, занимаюсь ... Чем-чем? Супец очередной довольно вкусный отведываю. Рецепт надо?..
