Wine Bottle, Glasses & Event Calculator

Wine for Events Guide

How Many Glasses Per Bottle?

A standard 750ml bottle of wine contains approximately: 5 × 150ml standard glasses (UK restaurant measure). 6 × 125ml glasses (smaller restaurant measure). 4 × 175ml glasses (generous home pour). For Prosecco/champagne flutes (125ml): 6 glasses per bottle. For event planning, use 5 glasses per bottle as a safe standard. If you serve very generous pours or have dedicated wine drinkers, plan for 4 glasses per bottle. One bottle of wine contains approximately 9 UK units of alcohol at a standard 13% ABV, a useful figure to bear in mind when planning quantities against recommended weekly drinking guidelines.

What should I know about Quantities by Event Type?

Dinner party (3 courses, 2-3 hours): approximately ½ bottle per person for moderate drinkers, ¾ bottle for heavier drinkers. Reception (standing, canapes, 2 hours): approximately ½ bottle per person. Wedding (ceremony + full reception, 6-8 hours): 1-1.5 bottles per drinking guest — weddings generate higher consumption due to toasting, long duration, and celebration atmosphere. Casual party (3-4 hours): ½-¾ bottle per drinking guest. Toast only, lasting 10-15 minutes: 1 glass per person, roughly equating to 1 bottle for every 5-6 guests.

What do I need to know about Chilling and Serving Temperature?

Serving temperatures: light red wine (Pinot Noir, Beaujolais): 14-16°C. Full-bodied red (Cabernet, Merlot): 16-18°C — room temperature is fine in UK homes. Light white wine (Sauvignon Blanc, Pinot Grigio): 7-10°C. Full-bodied white (Chardonnay): 10-12°C. Rosé: 8-10°C. Sparkling wine / Champagne: 6-8°C. Chilling guide: fridge (4°C) takes 3 hours to chill a room-temperature bottle. Ice bucket: 20-30 minutes. Freezer: 20 minutes (do not forget!). For a large event: a plastic cool box with ice and water chills bottles faster and more evenly than ice alone, and scales far better than fridge space for a big gathering.

What's the key thing to understand about Budget and Quality?

The sweet spot for quality vs price in UK wine retail (2024): under £7: very mixed quality — you can find decent supermarket own-label. £8-12: significantly better quality — this is where most reliable wines sit. £12-20: noticeably better complexity, more interesting producers. Above £20: diminishing returns for most occasions. For a party: a solid £10-12 bottle will please most guests and cost no more than £120 for 10 bottles. Buying a case (12 bottles) usually gives a 5-10% discount. Supermarket own-label wines at this price point have improved considerably in quality over recent years, often outperforming similarly priced branded alternatives.
