Need help in selecting a white wine

[stevebody]

Culi,

Second to IK's suggestions, with some addendums: Italy's whites - except for the rapidly-becoming-ubiquitous Pinot Grigio - are among the most overlooked whites in the world. In terms of sheer complexity and diversity of flavors, the Feudi di San Gregorio Greco di Tufo (a Wine Spectator Top 100 selection for 2002) is one of the only whites I've ever bought that is as interesting as a good red. It has a remarkable palate and develops nuances as it breathes. Another idea is any one of the excellent Soaves from Anselmi (San Vincenzo or I Capitelli), Pieropan (The basic Classico or the La Rocca), or Gini (Classico or La Frosca). These wines offer flavors of nut, orange and lime rind, white flowers, cantaloupe, buttermint, and on and on. Delicious stuff!

Finally and maybe most of all, I suggest the Bruno Giacosa Roero Arneis. A lot of other producers make Arneis, most notably Cassina Chicco and Vietti, but the Giscosa is Viognier-like in its voluptuous palate, intense and powerful aromas, and lovely, glycerine-ish mouthfeel. It's a little pricey but should come in under your $20 ceiling.

One last thought: If complexity does it for you, think outside of the single-varietal box. Blended whites can be awesome; examples, the Caymus Conumdrum (perennial delight), Coppola Bianco, Botromagno Gravina, and especially the Bonny Doon Il Pescatore, an absolute stunner at around $15.
There are an increasing number of the white Meritages around and all seem to be at least interesting and drinkable.

Hope these help.
