WOODAN Caskmarks has been set up to provide an overview of marks on casks and to enable specific searches for particular marks on casks using their associated specifications. A description of the fields is provided under the heading "Description of the fields". You can search by characteristics of the mark, the date of the mark or the design of the mark.
Characteristics of the mark:
The date of the mark:
The design of the mark:
Each mark can be divided into specific elements. These elements can be entered separately into a search field, allowing for easy searching of similarly designed marks. For instance, a hashtag symbol (#) can be searched for by entering “2” in the field Horizontal stripes and “2” in the field Vertical stripes. The search field options are: Horizontal stripes, Vertical stripes, Diagonal stipes, Waving lines, Circles, Half Circles, Dots, Crosses, Numbers, Figures, V-Shapes, W-Shapes and Letters.
To understand the use and significance of these marks, several types of cask marks were distinguished. These types are categorized based on their intended purpose. The marks served various functions, ranging from quantification and indicating ownership to the gauge or production process. Six main types were identified in total, most of which were further subdivided into subtypes, yielding eleven subtypes overall (Fig. 1).

Production marks were added during the first phase of a casks’ lifecycle, known as the production phase, by the coopers who crafted them. These cask marks are divided into construction marks and coopers’ marks. Both served a distinct function and have a unique set of features, which are described below.
The construction marks were applied during the production phase or repair of the casks by the cooper (Fig. 2). These marks are found on the bilge or heads of a cask and are usually of a relatively simple design. By marking lines when laying out the staves or head parts, it becomes easy to return a component to its correct place. This type of marking was often made with a knife, though in some cases, a timber scribe was used.
Figure 2: An example of a V shaped construction mark on a head (ID0428).
This mark is applied by the cooper after the cask's production process is complete. It serves to quantify the cooper's production and to trace the producer in case of a poorly made cask. The coopers’ mark was applied using either a timber scribe or, in some cases, with a knife. This cask mark type, is placed on the inside or outside of the heads of bilge (Fig. 3). The design consists of a monogram or simple combination of lines or circles.

The cask gauge mark was applied to casks at the end of the production phase, in preparation for use as transport containers. This cask mark was part of the gauging process carried out by inspectors (keurmeesters, or branders) appointed by urban authorities or guild boards. They assessed both the overall quality and the volume capacity of the cask. This inspection was crucial for ensuring the quality of the product being transported.
The cask gauge approval mark was applied to casks by urban inspectors upon confirmation that the cask met all the requirements of the gauging process. The prescribed dimensions, for instance, had to be checked using certain gauge instruments, a ring, bracket, or calipers. A cask bearing this type of mark could then be used as a transport container (Fig. 4).

If a cask did not meet the requirements for that specific cask, the city inspector would apply the cask gauge rejection mark. Rejected casks could be repaired by a cooper, after which the assessment process would be repeated. When the required repairs were completed, the inspector would replace the cask gauge rejection mark with the cask gauge approval mark and the cask would again be fit for use (Fig. 5).

Content gauge marks were applied during a casks’ use as a transport container, initiating the second phase of a casks’ lifecycle. Certain products had to be inspected by officials and had to meet specific quality standards, as was customary with herring where inspectors checked the quality of the fish and ensured it had been properly packing and salted. If the contents of a cask met all regulations, they were approved and the cask was marked with a content gauge approval mark. Conversely, contents that failed to meet the required criteria were rejected and the cask marked with a content gauge rejection mark.
The content gauge approval mark was applied to casks by inspectors upon confirmation that the contents met all the prescribed requirements of the gauging process. A cask bearing this type of mark could then be transported or traded (Fig. 6). The content gauge approval mark assured producers, traders, and consumers that the gauging process had been successfully completed.
Inspectors applied the content gauge rejection mark to casks whose contents failed to meet the required standards during the gauging process (Fig. 6).

The product identification mark was applied to casks to describe the product it was carrying, and was placed on the casks by the producers of the merchandise (Fig. 7).
Figure 7: Example of a product identification mark (ID0010).
This type of mark was used in the same way as signatures functioned in the Late Middle Ages and Early Modern period. The marks, thus, are found in a wide range of contexts, for example, on gravestones and house facades, and in personal letters and legal documents (Fig. 8).

Corporate identification marks were applied by a specific corporate entity and were used to identify the owner of a cask and its contents by that company, or to indicate that the contents of the cask were produced by a specific corporate entity. An example of a corporate identification mark was found on the VOC ship De Amsterdam, which sank near Hastings, England, in 1749, and which bore a VOC mark of ownership. Beer casks filled with beer from a particular brewery were also often marked with corporate identification marks (Fig. 9).

The count was used to quantify casks or the load they carried (Fig. 10). The design of this cask mark type consists of a system of lines and cross lines. The combination of these lines indicates a number. The count marks are usually applied with either a knife of timber scribe on the bilge of exterior of a head.
Figure 10: An example of a count mark on a stave (ID0777).
Content quantification marks were applied to casks after they arrived at their destination, where the contents were quantified by officials appointed especially for this task. Quantification was necessary because merchants were required to pay market tolls or excise duties to the urban authorities or to those who had leased the excise rights from them, and these tolls were based on quantity. The content quantification marks indicated officially measured contents from which was used to calculate the amount of excise duties required, based on applicable rates (Fig. 11).

This is the homepage where you can find search fields for the characteristics, date, or design of the mark. The search results will display an image of the mark along with its type and the ID number of the cask mark.
By clicking on any individual cask mark, you can select it. Upon selection, you will be directed to a page displaying all the available information for that particular mark. Often, not every field will have data. By using the ‘Show empty fields’ option, you can choose to display these fields or keep them hidden.
The table tab displays the search results in a tabular format. By default, the table shows the ID number, image, type of cask mark, location of the mark on the cask, method of application, associated product, context type and the municipality where the mark was found. The search field at the top of this tab allows you to search across all available fields in the database, so also fields that aren’t shown in the table tab display.
The maps tab displays the search results on a map, with each icon representing an individual cask mark. It is advisable to zoom in closely, as many of the cask marks were found in close proximity, causing the icons to often overlap.
New marks can be added to WOODAN Caskmarks by completing the input file downloadable from this link. This file can be sent to info@woodan.org. These data will be verified by one of the involved researchers to ensure the reliability of the information in WOODAN Caskmarks. After this verification, the data will be made available online.
The development of WOODAN Caskmarks has been supported by a grant from the Samenwerkende Maritieme Fondsen.
WOODAN Caskmarks is connected to the article: Oosterbaan, J. (in preparation). Marks on Casks.
The database model was made by Jeroen Oosterbaan. Data entry was done by Liam Tran, Wouter Donders and Jeroen Oosterbaan.
