All that the proud, rooted people of Gurgaon-Gurugram now need to develop is a ’Gram Culture – apart from visiting malls and believing that microbreweries are really art galleries, minus the art. But then, cutting-edge brand-hurrahing irony that is indigenous will have to be dredged up from somewhere outside Madmen and Mad magazines.
The first one I think is a metaphor.What it intends to say I don't know.Also, a single apostrophe before Gram appears to be a typo.
'Gram culture
Apostrophes can be used to mark abbreviations and contractions. So 'Gram is an abbreviation since the full name of the city is "Gurugram". Calling it 'Gram Culture is fitting since it calls attention to the name change from -gaon to -gram.
So the author believes they need to develop a culture that the author is calling 'Gram Culture.
Now, part of the sense of "culture" here is
culture
a : enlightenment and excellence of taste acquired by intellectual and aesthetic training
b : acquaintance with and taste in fine arts, humanities, and broad aspects of science as distinguished from vocational and technical skills
In other words, there should be a level sophistication associated with this so-called Gram Culture. By writing
believing that microbreweries are really art galleries, minus the art.
I believe the author is making a joke. He is saying that microbreweries do not count as art. So having them as part of the Gram Culture does not really add sophistication to the culture.
brand-hurrahing
One of the definitions of hurrah is
hurrah
hubbub; commotion; fanfare
It is noun, but by writing "brand-hurrahing", I think the author is saying something like "making a commotion about brand(s)", or simply "brand advertising".
