Editing Provenance (section)

==Wines==
In transactions of old wine with the potential of [[Storage of wine|improving with age]], the issue of provenance has a large bearing on the assessment of the contents of a bottle, both in terms of quality and the risk of [[wine fraud]]. A documented history of [[wine cellar]] conditions is valuable in estimating the quality of an older vintage due to the fragile nature of wine.<ref name=OCW-ageing>winepros.com.au. {{Cite web|last= Oxford Companion to Wine|title= ageing|url= http://www.winepros.com.au/jsp/cda/reference/oxford_entry.jsp?entry_id=30|access-date= 2008-04-28|archive-url= https://web.archive.org/web/20080726225615/http://www.winepros.com.au/jsp/cda/reference/oxford_entry.jsp?entry_id=30|archive-date= 2008-07-26|url-status= dead}}</ref>

Recent technology developments have aided collectors in assessing the temperature and humidity history of the wine which are two key components in establishing perfect provenance. For example, there are devices available that rest inside the wood case and can be read through the wood by waving a smartphone equipped with a simple app. These devices track the conditions the case has been exposed to for the duration of the battery life, which can be as long as 15 years, and sends a graph and high/low readings to the smartphone user. This takes the trust issue out of the hands of the owner and gives it to a third party for verification.{{citation needed|date=April 2021}}
