What is the correct pronunciation of "malvasia bianca?"

I'm leading a wine tasting tomorrow and one of the wines is malvasia bianca. When I search on the web I see confilicting opinions on which syllable to stress. Is there a "correct" pronunciation?

Bear in mind that all "a" sounds in Italian are pronounced " ar". As in car.  So instead of saying Mal as in pal it woul be marl....then vars Eeya.
Bianca, meaning White is pronounced again with the a sound as  ar not as in cat....as we do for the girls name Bianca....its BEE ARN CAR.  does that helpr .
So we have MARL...VAR SEE AR.. said quicker of course... Then BEE ARN CAR. For.bianca
good luck...hope that helps... Diana

Thanks for the pointer about pronouncing the "a," but does anyone have an opinion about where to place the stress? I've seen sites that stress the second (uh, Wiki...), and the third syllable.
 

Ciao Steve.....Most Italian words have the stress on the second last syllable . The stress is on the  " var" part of the word Malvasia . With the Bianca it definitely is on the second last syllable... Bi A nca

Ciao Diana,

the best way to pronounce it is :
malvazia bee-an-kuh

As Grahame correctly suggest, please refer to google translate and listen to the pronunciation making sure that you select Italian as the language.

I hope this helps.
