The only time I get real Coke made with sugar is when I'm out of the country. I like the smoother taste that real sugar helps bring to the party vs high fructose corn syrup (HFCS). On these occasions it seemed that the bottles has more pressure in them compared to the US. They "popped" when you unscrewed the cap on a cold bottle.

I alway chalked it up to how they do things outside the US. Today, while food shopping, I ran across Kosher for Passover Coke on an endcap in the supermarket, on sale no less 3-2 liter bottles for $3.00.

In case you don't know what the big deal about Kosher for Passover Coke is, this is the true original recipe Coke made with sugar instead of HFCS. Someone that knows more about this then me can explain why corn syrup is not Kosher during Passover.

Either way, it just tastes better then Coke with HFCS.

I'm happy that I got several bottles of sugar sweetened Coke without leaving the country. I took them home chilled one, and later poured myself a nice cold glass.

I noticed that when I unscrewed the cap for the first time the bottle "popped" just like it did in the other countries.

Do they add more gas to Coke with sugar? Does the use real sugar makes it harder for it to stay carbonated?
