i just got back from the suntec fair as well. we tried quite a number of wines.
my gf got a sparkling moscato drinks. semi sweet, fine bubbles, overall delicious easy drinking wine.
in the end the 2 bottles i bought i didn't try them at all.
09 J Boutin Hermitage "Arena Mica" - 100% Syrah from the Northern Rhone. This has gotta sleep for a while.
09 Shaw & Smith M3 Chardonnay - 100% Chardonnay. Their top end chardonnay, but gotta sleep for at least 5 years first.
Overall, lots of entry level wine for tasting, but i think if you came earlier (i started at 8pm) there were perhaps more selections.
The small booth by Culina letting you sample their Miguel Torres Hemisfero Caremenere, that was a pretty good wine for the price. well made, good varietal character from a good producer. 100% Caremenere grapes.
Go to the shelves selling the various Rhone wines. Target the Cote Rotie, Hermitage, Cotes du Rhone, Gigondas & Chateauneuf du Pape. Check out the cremant de alsace (sparkling alsatian wine).
lots of bordeaux for sale as well. some aged ones too, but do your research before buying them.
