To willp58, I will tackle a few of the terms. If I'm wrong, someone will probably correct me. Grosset may be winery or producer and Polish Hill a vineyard or brand name. Wondering if Alsacan means Alsatian (wines from Alsace, French province bordering Germany) or if its not a typo but an altogether different name. A varietal is a type of grape such as riesling, sauvignon blanc, zinfandel, pinot noir, syrah or shiraz, chardonnay, pinot gris or pinot grigio, merlot, sangiovese, nebbiolo, etc.
A wine made from a riesling grape in California should have certain aroma/flavor similarities to a wine made from a riesling in Germany or New Zealand or Alsace. But the soil and climate (which contribute to "terroir"--sense of territory of a specific piece of land), growing methods, winemaking methods and clone used will make for differences in the rieslings from different locales. I take "heft" to mean weight or body. A wine that seems weighty in the mouth--that maybe has a lingering finish after swallowing. Vinman is saying that rieslings are not noted for heft or oak taste imparted by fermenting and/or storing in oak barrels. A wine with lots of heft doesn't taste watery or fleeting. Quaffing refers to lighthearted or light in body wines, pleasant to drink in large gulps, not needing food to balance tannic acids or out-of-balance acidity. If your mouth is puckering or drying out from acid or tannins, then the wine is not an easy drinker. "Mellow" is a term I sometimes use for the easy drinkability of a riesling with some residual sugar left after the wine completes fermentation. In an analogy, you might "quaff" apple juice in large swallows but might choke on a large swallow of bourbon or brandy if you are not used to alcoholic beverages. Hope this helps. Maybe Vinman will respond and correct what he was really saying.
