Was it a still moscato, or an asti moscato (kinda fizzy).? If it was a still, try looking for half bottles of sweet wine from the US or Canada in your good wine shop's desert section. California makes some interesting desert wines from muscat grapes, some not so pricey. (We are from Colorado, a state that makes it a huge problem to get mailed wine.) If you love to read about Italian food and wine, read Frances Mayes "Under A Tuscan Sun and "Bella Tuscany" books. She has the most wonderful story about Vin Santo (wine of the saints), Tuscany's version of desert wine heaven. We once had some special Vin Santo at the Epcot Food and Wine Fest special Tuscan Reserve dinner that was to die for.
Ice wine (eiswein) is often Reisling grapes. California, et. al. also make some comparable products. The reason it is so dang pricey, is the season must be very long, dry and hot to allow the grapes to ripen, dry a bit and concentrate the sugar, then must come a freeze of just the right amount.
France has an even more involved version of desert wine, the grapes even must "noble rot" and now we are talking REALLY serious $$$$$.
But if you really wanna curl your socks, try grappa, a sweet brandy made from all the gunk left over AFTER they make the Italian wine (like grape seeds!).
