bro wine is my life. it's really tough to recommend not knowing your tastes or your girl's tastes or your experience. not to sound all high brow but the palate grows and becomes more demanding with experience. i could tell you shit that's out there right now that i think is the best thing i ever tasted for 20 bucks but you might not see the beauty of it cause you just don't have the palate time where as i taste anywhere from 20-100 wines a week..
ok that being said there is nobody and i mean nobody on this earth who won't flip over a good bottle of moscato d'asti -which translates from italian as "panty remover" . it's lightly sparkling - what the italians call "frizzante". its also has some residual sugar so it'll be sweet, but if it's a good one it willnot be sticky sweet and so delicious you'd better get two bottles. one for before dinner, one for after. wouldn't recommend it with dinner, but it'd be great for desert. go to a good store and ask for a recommendation. expect to pay 12-15 bucks a btl.
you get what you pay for so don't mess around with any crap for less money unless the guy really knows his shit and is recommending it.
you could also go with champagne. nobody turns their nose up to champagne. again i mean real frickn champagne. bollinger, pol roger, taittinger, veuve-cliquot-chicks dig veuve cause it's owned by a woman. but there you're starting at 30 bucks a btl, and for the brands i just mention more like 50 and up. and you will score points with cahmpagne for sure but you won't get the oh my god this is sooo freakin good i want to slurp it outta your naval response you will with the moscato d'asti. the italians know what's frickn goin' on let me tell ya.
