Daily BottlePicker evidence
Most variable tracked drinks prices in the UK
The widest measured gaps between each bottle’s lowest and highest retained daily best price. This describes tracked ranges, not financial-market volatility.
Updated: 15 Aug 2026 · 73 qualifying bottles
What the current data shows
73 bottles qualify across 17 market snapshot dates from 18 Jul 2026 to 15 Aug 2026. Kahlua White Coffee Liqueur (70cl) currently leads this measured view at 45.8% across 14 retained daily snapshots. The result is a reproducible catalogue observation, not a forecast, recommendation or claim about every UK retailer.
Most variable prices: current ranking
Methodology and limits
Every row uses one exact BottlePicker product, one currency and the lowest retained daily per-bottle price among tracked UK retailers. A series must contain at least three daily observations and one price change. Values below £1, above £5,000 or with a low-to-high range above 100% are excluded as likely identity or pack-size anomalies.
“Current” means the latest retained daily snapshot, not a guaranteed checkout price. Delivery, coupons, loyalty prices and separately labelled live-shopping results are excluded. A price fall is not automatically a merchant-advertised sale, and a wide range is not a quality or investment score.
