Vişne suyu çok ekşi, ama ben yine de içmeden edemiyorum.

Vişne means sour cherry, while kiraz usually means sweet cherry.

So:

• vişne suyu = sour cherry juice
• kiraz suyu = sweet cherry juice

This matters here because ekşi means sour, so vişne fits the sentence naturally.

Vişne suyu is a noun compound in Turkish.

In Turkish, compounds like apple juice, door handle, car door, etc. are often formed like this:

• first noun: plain form
• second noun: usually takes a 3rd person possessive ending

So:

• vişne + su → vişne suyu

Literally, this structure is something like the juice of sour cherry, but in natural English we simply say sour cherry juice.

Other examples:

• elma suyu = apple juice
• portakal suyu = orange juice
• köy yolu = village road

The base word is su = water.

In the compound, the second noun takes the compound ending, which here appears as -yu:

• su → suyu

This is partly because su is an irregular-looking word in some endings. Compare:

• su = water
• suyu = its water / the water / water in a compound
• sudan = from water
• suya = to water

So vişne suyu is the normal correct compound form.

Çok ekşi means very sour.

• çok = very / a lot
• ekşi = sour

In Turkish, adverbs like çok usually come before the adjective they modify:

• çok güzel = very beautiful
• çok zor = very difficult
• çok ekşi = very sour

Ama means but.

It connects two contrasting ideas:

• Vişne suyu çok ekşi = Sour cherry juice is very sour
• ama ben yine de içmeden edemiyorum = but I still can’t help drinking it

So the contrast is: It’s very sour, but I still drink it anyway.

Yine de means still, nevertheless, or even so.

It adds the idea that the second part happens despite what was said before.

So here:

• çok ekşi = it is very sour
• yine de = even so / still
• içmeden edemiyorum = I can’t help drinking it

A natural sense is: It’s very sour, but I still can’t help drinking it.

Other examples:

• Hava soğuk, yine de dışarı çıkacağım. = The weather is cold, but I’ll go out anyway.
• Yorgunum, yine de çalışacağım. = I’m tired, but I’ll work anyway.

Yes, the ending already shows the subject:

• edemiyorum = I can’t / I am unable to

So ben is not grammatically necessary.

Turkish often drops subject pronouns unless they are needed for:

• emphasis
• contrast
• clarity

Here ben adds emphasis, something like:

...but I still can’t help it or ...but as for me, I still can’t stop myself from drinking it

So the sentence without ben would still be correct:

• Vişne suyu çok ekşi, ama yine de içmeden edemiyorum.

Literally, it breaks down like this:

• içmek = to drink
• içmeden = without drinking
• edemiyorum = I cannot do

So word-for-word, it looks like:

I cannot do without drinking

But this is an idiomatic Turkish structure. In natural English, it means:

• I can’t help drinking it
• I can’t stop myself from drinking it
• I can’t resist drinking it

So don’t translate it too mechanically.

İçmeden comes from the verb içmek (to drink) plus the suffix -meden / -madan, which means without doing.

Formation:

• iç- = drink
• -meden = without doing

So:

• içmeden = without drinking

More examples:

• gitmeden = without going
• yemeden = without eating
• konuşmadan = without speaking

The vowel changes according to vowel harmony:

• -madan
• -meden

For içmek, the correct form is içmeden.

Because this is a special idiomatic pattern:

-meden edememek

It means:

• cannot help doing
• cannot refrain from doing
• cannot resist doing

So:

• içemiyorum = I can’t drink
• içmeden edemiyorum = I can’t help drinking

These mean very different things.

Compare:

• Kahve içemiyorum. = I can’t drink coffee.
• Kahve içmeden edemiyorum. = I can’t help drinking coffee.

The second one expresses compulsion or irresistible habit, not inability.

Yes, it is a fairly common and useful pattern.

Structure:

verb stem + -madan/-meden + edememek

Meaning:

• can’t help doing
• can’t resist doing
• can’t refrain from doing

Examples:

• Gülmeden edemedim. = I couldn’t help laughing.
• Sormadan edemeyeceğim. = I won’t be able to resist asking.
• Bakmadan edemiyor. = He/She can’t help looking.

So in your sentence:

• içmeden edemiyorum = I can’t help drinking it

This is a very natural expression.

Edemiyorum is in the present continuous / imperfective form.

Breakdown:

• et- = do
• -e-me- = not be able to
• -iyor = present continuous / ongoing or habitual present
• -um = I

So:

• edemiyorum = I can’t / I’m unable to

In this idiom, the -iyor form often gives a present, ongoing, or habitual sense:

• içmeden edemiyorum = I can’t help drinking it / I always end up drinking it

It can describe a repeated tendency, not only something happening at this exact second.

Turkish often leaves out objects when they are obvious from context.

Earlier in the sentence, we already have:

• Vişne suyu = sour cherry juice

So when the speaker says içmeden edemiyorum, the listener naturally understands:

• I can’t help drinking it
• meaning the sour cherry juice

This kind of omission is very common in Turkish.

If you wanted to say it more explicitly, you could say something like:

• Vişne suyu çok ekşi, ama ben yine de onu içmeden edemiyorum.

But this is less natural than simply leaving it understood.

The sentence has a very natural Turkish flow:

• Vişne suyu çok ekşi
• ama ben yine de içmeden edemiyorum

Turkish word order is flexible, but the default tendency is for the verb to come near the end.

Here the structure is:

1. topic / subject: Vişne suyu
2. description: çok ekşi
3. contrast: ama
4. emphasized subject: ben
5. adverbial phrase: yine de
6. verbal expression: içmeden edemiyorum

You could move some pieces for emphasis, but this version sounds natural and balanced.

For example:

• Vişne suyu çok ekşi, ama yine de içmeden edemiyorum.
• Vişne suyu çok ekşi, ama ben içmeden yine de edemiyorum. ← grammatical, but less natural

So the original sentence is a good model to follow.

The most natural translations would be things like:

• Sour cherry juice is very sour, but I still can’t help drinking it.
• Sour cherry juice is really sour, but I drink it anyway.
• Sour cherry juice is very sour, but I just can’t resist it.

The exact English version depends on how strongly you want to show the sense of içmeden edemiyorum.

If you want to preserve the Turkish idiom most closely, I can’t help drinking it is the best choice.
