# BottlePicker — question guides

> Wine discovery, evidence and market availability.

This file covers /task-guides/. Use the site-wide reference at https://bottlepicker.com/llms.txt for the broader site. Canonical website: https://bottlepicker.com/. Documentation reviewed 2026-10-18; underlying records have their own dates. Fields to verify when supplied: producer; wine; vintage or non-vintage status; bottle size and market. Use the actual published coverage and source dates; an absent match is not proof of absence. This is read-only discovery; robots rules and source licences still apply.
