Here's a start, off the top of my head and obviously not even half complete. Throw them out for inclusion. If someone wanted to do a list of common usenet acronyms (IMHO, YMMV, etc) have at it!
What do those abbreviations mean?
Commonly used wine term abbreviations: AP Number. Amtliche Prufungs, official number given each quality wine in Germany BA: Beerenauslese (next to highest level of Pradikat, always botrytis affected) GKA/LGKA. Gold Kapsel Auslese and Long gold Kapsel (unregulated ways for producers to distinguish bottlings they think better, kind of "reserve" for Germany QbA : Qualitätswein bestimmter Anbaugebiete (quality wine, level below QmP) QmP : Qualitätswein mit Prädikat (Pradikat levels are Kabinett, Spätlese, Auslese, Beerenauslese, Eiswein or Trockenbeerenauslese) SGN: Sélection de Grains Nobles (similar to TBA, used in Alsace and the Loire) TBA: Trockenbeerenauslese (highest degree of ripeness in Qmp classification) VT :Vendange Tardive (late harvest)
The next group is types of wine/regions, a bit less standardized. I'd suggest writing out the entire word the first time, and then using abbreviation for brevity ("I like Cotes du Rhone wines. My favorite CdR is....")
BdM Brunello di Montalcino CalCab California Cabernet CCR Chianti Classico Riserva CdB Côte de Beaune CdL Coteaux du Layon CdN Côte de Nuits CdP Châteauneuf du Pape CdR Côtes du Rhône NSG Nuits St. Georges QdC Quarts du Chaume RSV Romanee St Vivant VP Vintage Port
Same goes for grapes: CF Cabernet Franc Chard- Chardonnay CS Cabernet Sauvignon GV Grüner Veltliner PB Pinot Blanc PN Pinot Noir SB Sauvignon Blanc Zin Zinfandel
There are many producers or individual wines that are well-known enough that many winelovers often use abbreviations (LLC is Leoville las Cases, VCC is Vieux Chateau Certan, ZH Zind-Humbrecht, CFE Cuvee Frederic Emile, many others) ,but in the interest of clarity again in those cases it's much better to write out first time. Exceptions would be the very few which are so well-known and so commonly abbreviated that the abbreviation is the norm: BV is Beaulieu Vineyards, DRC is Domaine Romanee Conti (so you can have DRC RSV). Of course any longer term can be abbreviated if in context (if one is writing a tasting note on a Bonneau du Martray Corton Charlemagne, it is understood that if one then says BdM you are not saying Brunello!).
If you're confused, ask!
