Mandatory vs voluntary information
EU and UK wine labelling law mandates a set of minimum disclosures on every bottle: ABV, net volume, country of origin, allergen warnings, lot number, importer details and (since 2023 in the EU) nutritional information or a QR code linking to it. Everything beyond this — tasting notes, food pairing suggestions, serving temperature, winemaking notes — is voluntary. Knowing this helps you read the label efficiently: mandatory fields are facts; voluntary fields are marketing.

Back label elements and their usefulness
ABV as a style indicator
Alcohol content is one of the most useful quick-reads on the back label. Below 11% ABV typically signals a cool-climate or intentionally off-dry wine — German Riesling Kabinett, Moscato d'Asti, Vinho Verde. Between 12.5% and 13.5% is the range for most dry European table wine. Above 14% suggests a warm-climate wine with full extraction — common in Napa Cabernet, Australian Shiraz, Chateauneuf-du-Pape. 15–22% marks fortified wines. ABV also gives a rough indication of body: higher alcohol generally means fuller body, lower alcohol means lighter body. For how alcohol relates to style, see the main grape varieties guide.
The importer as a quality signal
A respected importer is one of the most underused quality signals on the back label. Specialist importers — those who work with small, artisan or regional producers — typically apply stringent selection criteria. In the UK, importers like Raeburn Fine Wines, Swig, Les Caves de Pyrene, Faber Wines and others have built reputations for consistently excellent selections. When you find a wine you love through one of these importers, exploring their broader portfolio is often a reliable way to discover new regions and styles.
