To me, by the fireplace is a great place for a picnic or anything else. But, by far, the most romantic wines in the world are the wines from Burgundy.
The reds are soft and velvety, smooth and warm.
But, they are also expensive.
I would skip the German wine because to me, the last Romantic German died in the 19th century. For the white, try a Sancerre, which is fruity and citrussy enough for your palate, and yet, not too sweet, as your boyfriend prefers dry.
