Methodology

About BottlePicker

BottlePicker is an alcoholic-drink price and retailer comparison organised into 21 separate, localized country sections.

Country separation

Every market has its own URL namespace, language, shopping locale, merchant registry and currency filter. Offers in another currency are rejected rather than converted or mixed into the comparison. Newly launched country shells remain noindex,follow until at least 500 current local-currency products are supplied by 2 active merchant feeds with in-stock prices.

Merchant tracking status

The registry currently contains 100 merchant profiles across 21 country sections. 48 are marked as active feeds; 52 are configured or paused profiles and are not described as currently harvested. Each profile can store source type, automation level, category scope, delivery method, geographic coverage and legal-age requirements.

Collection methods

The generic tracker supports Shopify product JSON, XML sitemaps with Product JSON-LD, merchant-filtered shopping-provider discovery, and custom or manual adapters. Every collection run can be logged with its market, source, status, record count and error detail. Historical offers remain in the database; current country aggregates use only in-stock records in the matching currency.

Product scope

The product model covers wine, whisky and whiskey, gin, rum, vodka, tequila and mezcal, brandy and cognac, liqueurs and aperitifs, beer, cider and perry, mead, sake, and ready-to-drink cocktails. Non-alcoholic products, accessories, mixers, events and gift-only listings are excluded where they can be identified reliably.

Tracked and live results

The catalogue currently has 15,691 distinct products with tracked stock and 20,231 current tracked listings. Live shopping results are fetched on demand and displayed separately. They do not alter tracked catalogue totals, retailer feed status, price history or structured product offers.

Vineyard and producer data

The structured vineyard layer currently contains 12 vineyard or named-parcel records supported by 12 source records. It can store site boundaries and coordinates, appellation, area, elevation, aspect, slope, soils, geology, grape varieties, rootstocks, clones or selections, planting history, density, training, row orientation, irrigation, farming, certifications and harvest method. Product-to-vineyard links carry a relationship type, confidence value, notes and optional percentage. Links are conservative: a producer or regional name alone is not treated as proof that a wine came from a specific site.

Prices and product identity

Exact GTIN matching is preferred when a barcode is available. Text fallback uses product name, brand, vintage and container size checks. BottlePicker also compares sufficiently complete wine and spirit records with the LWIN identity dictionary using indexed exact producer or bounded name-prefix lookups; ambiguous matches are rejected rather than guessed. LWIN data is by Liv-ex Ltd. under CC BY 4.0, and BottlePicker adds the matching decision. Pack prices are retained as checkout prices and may also show a calculated per-unit amount. The retailer remains authoritative for identity, pack size, taxes, duties, delivery, stock, legal purchasing requirements and final checkout price.

Update cadence and data honesty

BottlePicker launched in July 2026 and is under active development. Merchant snapshots are collected in dated runs rather than on a fixed promise of freshness; every tracked offer displays the date it was last seen, and offers that stop appearing are marked out of stock rather than deleted. Country sections and category pages with no successfully tracked data say so plainly — and are excluded from search-engine indexing — instead of being padded to look fuller than they are.

Analytics and privacy

BottlePicker offers an optional Google Analytics measurement. The Google Analytics script is not loaded and no Analytics measurement request is made unless a visitor selects “Accept analytics”. The choice is stored on that device and can be changed using “Analytics privacy settings” in the footer. Advertising storage, advertising user data, ad personalisation and Google Signals remain disabled. Search Console verification does not track visitors.

Who runs BottlePicker

BottlePicker is operated by 37x Limited (Guernsey non-cellular company CMP76157) and built and run by Doug Scott, founder of the shopping-comparison company Redbrain. Its registered office is Les Echelons Court, Les Echelons, St. Peter Port, Guernsey, GY1 1AR. The site applies the same discipline used in mainstream product price comparison — feed collection, GTIN identity matching, currency isolation and honest availability states — to alcoholic drinks. Product pages place clearly labelled commercial partner links before retailers for which BottlePicker has no confirmed commercial terms. Prices within each section are ordered by calculated per-unit price, and non-commercial listings remain visible for comparison.

Contact and corrections

Wrong price, dead link, a product matched to the wrong identity, or a retailer that should or should not be listed? Email hello@bottlepicker.com and reference the page URL. Corrections that survive verification are applied to the underlying registry and data, not patched cosmetically. BottlePicker does not publish a telephone contact.

Responsible use

BottlePicker is intended for adults legally permitted to buy alcohol in their location. It does not sell alcohol directly.
