QbA (Germany)
The labelling term QbA (Qualitätswein bestimmter Anbaugebiete) literally describes a "quality wine from a designated region". It is a lower quality category than QmP, permitting the addition of süssreserve. Wines classified as QbA are occasionally of interest, but frequently are not!

QmP (Germany)
The term QmP is an abbreviation for Qualitätswein mit Prädikat, which literally interprets as "quality wine with distinction". The distinction is the Prädikat, which contains a number of categories which depend on must weight. This is the classification for the vast majority of German wines of any interest.

Quality Control
The series of analyses and tests that verify a wine's palatability, stability, compliance with regulations, and absence of faults.

Quinta (Portugal)
A term describing a farm, estate or vineyard. The individual quintas of the Port houses became of interest with the development of the single quinta Ports, initially bottled in non-declared vintages but now bottled in these years as well by some houses. See my Port house profiles for more information.
