Abstract

The scope of this ontology is to help provide traceability for beer by providing a database of all known hop varieties as well as their components and properties that add flavoring to the beer. This is so that brewers can be assured they know exactly what they are getting when selecting hops for a beer and to help manage their inventory. This will also help suppliers provide brewers with testing data and integration with the inventories of the brewers.

Table of Contents

1. Introduction

Hops are the flower seed cone of the Hop (Humulus lupulus) vine that are primarily used for adding flavoring, or bitterness, to beers. Hops thrive mostly in the Northern hemisphere, but it is cultivated in Australia, New Zealand, and South Africa as well. Hops can be either male or female, but only the females produce the seed cones used that are valued for brewing.

The Hops Ontology was created to help provide traceability for brewers and to help brewers find the best match for the beer they want to brew.

Unlike wheats, which are aggressively tracked, hops are identical to the first hop plant that was brought to a new location despite being grown and cross pollinated for years in a new environment. For example, are the Cascade hops that have been grown for years in Europe after being brought over from the US genetically identical? What about the Magnum hops that have been grown for years in the US after being brought over from Germany? More research needs to be done to track the genetics and properties of hops. This ontology has started doing this, however more data needs to be collected from hopyards from various locations.

2. Brief History of Hops

According to Ray Neve, it is unclear when the first usage of hops came to be, there is a 3000-year-old Finnish oral saga, however it is unreliable since it likely has been altered or having additions. The first written record of hops cultivation was in 736 AD (Linke and Rebl, 1950) that tells of Wendish prisoner who had a hops garden in German. The Wends were Slavs, and the Slavic term for 'hops' was 'hmelj', which has Finnish origins therefore potentially corroborating the Finnish saga.

There is also a list of goods, that includes hops, from Bohemia to Hamburg that dates back to 1101 AD. Hop cultivation declined in Czech countries during the Thirty-Year War and clippings were brought to surrounding areas. In the 14th century hop cultivation spread to western Europe, which they were specialized locally as hopped beer as opposed to unhopped ale.

It wasn't until the 19th century that Germany became the leaders in hop production and beer brewing. Even now in the 21st century, beer brewing is still more of an art than a science. It is still unknown what oils cause which flavoring. Indeed, the aroma and taste tests are almost entirely subjective.

3. Scope of this Ontology

The Hops Ontology is used to help with the traceability of hops to make choosing hops easier for brewers to achieve the flavors they desire in their beers. Since there is much in terms of flavonoids in varieties that are not well documented, not to mention the effect of terroir.

Therefore, by providing proper documentation on the origins and testing done on the hops as well as the type of hop will help brewers make more informed choices on what hops to use for either a new brew or to maintain consistency in popular recipes. This also can help local hop yards increase their business by providing documentation and assurances of quality.

4. Organization

4.1 Hop Varieties as Classes

Hop varieties are subclasses rather than instances of the Hop Class. This was done since hop varieties will have instance data coming from different growers and different years.

Using hop instances directly as a product is difficult as crops are usually made into plugs or pellets before they are sold. Therefore, the hop instance is linked to a commercial product by prov:qualifiedUsage when the transformation process is defined and prov:wasDerivedFrom if the process is not documented.

4.2 Hop Plugs

Hop Plugs are not a subclass of the Hop Pellet class because the pellet class is specifically for hops that have undergone a drying, crushing, and pelletizing processes, while Hop Plugs specifically are not ground before being pelletized.

4.3 Fuggle and Goldings

Golding hops varieties are one of the oldest variety of hops, originating in the UK. It has been bred for centuries and is still being grown today. Due to the many years of cross breeding, many currently used varieties are quite diverse. Due to a naming mix-up that occurred when a Verticillium Wilt strain destroyed the hop industry in Yugoslavia, now Slovenia, in the 1930s, it was believed that the variety selected to rebuild the industry from England was a Golding variety. However, it was actually a Fuggle, hence the misnaming of Styrian Golding, as Styring was the name of the location where this variety of Fuggle began to be grown and bred.

This ontology was organized to respect the lineage of these varieties despite the misnomers. Below describes the instances where this issue has arisen as well as some identification issues with the USDA.

4.3.1 Yugoslavia Golding

Yugoslavia Golding is an identical hops variety to Styrian Golding. However, the USDA has an accession number for both names, therefore both classes were created as subclasses of HopsFuggle. HopsYugoslaviaGolding also has owl:equivalentClass to HopsStyrianGolding, but not vice versa since this variety of hops is mostly known as Styrian Golding. Also, the USDA has Yugoslavia Golding as a synonym for Styrian Golding but not Styrian Golding as a synonym for Yugoslavia Golding. By doing this, both USDA accession numbers are preserved as well as the previous Plant Identifier (PI) number that was only referenced by the USDA under Yugoslavia Golding.

4.3.2 East Kent Golding

A similar issue is with East Kent Golding and Canterbury Golding. East Kent Golding refers to the variety of hops from the Kent region of England, of which Canterbury is a town. The USDA even states that it is identical to East Kent Golding, however it still gives Canterbury Golding an accession number. Similar for Yugoslavia Golding, a new class was created so that the USDA accession numbers align, and equivalencies were made so that the properties are consistent.

4.3.3 Savinski Golding

Savinski Golding is claimed to be a clonal selection from a Fuggle in Yugoslavia and appears to be identical to Styrian/Yugoslavia Golding. It is unknown why this hop has its own accession number. However, both Savinski and Yugoslavia Golding originate from different PI numbers. This is most likely the reasoning behind the multiple accession numbers. Therefore, Savinski Golding will be a subclass of Fuggle and be an equivalent class of HopsStyrianGolding so that the USDA accession numbers are respected.

4.4 Hersbrucker

It seems that there were many samples taken of the Hersbrucker hops by the USDA and all of them received USDA Accession Numbers despite being the same variety. There were also some discrepancies in terms of which sample is equivalent to what hops.

It was determined that there were four different types of Hersbrucker hops: Hersbrucker (G, Late, Spät); Hersbrucker E; Hersbrucker Pure; and Hersbrucker Red Stem; which have been corroborated by multiple sources. However, there is a USDA sample called Hersbrucker-9 that claims to be a clonal selection of the original German Hersbrucker (Hersbrucker-G) but also claims to be equivalent to the English variety Hersbrucker E and also to the German variety Hersbrucker Red-Stem, which is impossible. Therefore, this ontology will go by the USDA's selection claim of being from the original German Hersbrucker, and not the others.

Similarly, Hersbrucker-alpha, a USDA sample, claims to have a pedigree equivalent to Hersbrucker-G, Hersbrucker E and Hersbrucker Red-Stem, which is unclear. The USDA also claims that this sample is equivalent to Hersbrucker Red-Stem. Therefore, this ontology will also add this USDA label and accession number in the Hersbrucker Red-Stem node.

4.5 Properties of Hops

All the known properties of hops are listed with a description (if available) of what flavor with which they are associated (if known).

4.5.1 Alpha Acids

Alpha acids are a group of acidic compounds that isomerize (add flavor) during the boiling process of beer brewing. They are found in the resin of the hop, however they are not considered oils, even though they are found in the hop oil.

4.5.2 Beta Acids

Similar to alpha acids, beta acids are also a group of acidic compounds found in the resin of the hops but are not oils, however beta acids isomerize (add flavor) over a longer period of time than the alpha acids, usually during the fermentation process of beer brewing.

4.5.3 Other Oils

There are still many unknowns in the composition of the hop oils or even which compounds cause which flavors. Therefore, the Hops Ontology lists all of the known compounds and known association with flavorings. So that if those compounds are shown on a hops profile they can be documented and if just "Other Oils" is shown then the Hops Ontology can handle that as well.

This ontology provides a central place to have all the known information on hop compounds as well as provide documentation on what exactly those compounds are and the procedures for how the testing of the compounds were done.

4.5.4 Storability

Storability is different than Hop Storability Index (HSI) in the sense that storability is the percentage of alpha acids that remain unoxidized after a fixed period (six months). The percentage associated with the Storability of a type of hop is given after several tests and is roughly what one would expect to see after six months of storage.

The HSI comes from testing a hop that has been harvested (or any point in time). The result shows the percentage of alpha acids remaining after that specific point in time.

4.5.5 Percieved Aroma

Perceived Aroma is a property that is hard to model since it is a subjective property. Therefore, several hops aroma profiles were gathered and the aromas that appeared the most were put in this ontology.

As hop research and analysis continues, it is the goal for this ontology to associate prominent oils with aromas so that aroma profiles could automatically be generated based on an analysis of the amount of acids and prominent oils.

4.5.6 Hops Grown in Other Countries

When one sees hops that are grown in different countries, such as Magnum (US) vs Magnum (DE), they are assumed to be genetically identical. The reason why there are multiple classes for hops that are the same (genetically) is due to terroir. This ontology shows that terroir has a large impact on hop aroma, which is why there are multiple classes for hops that may be genetically identical.

4.6 Taurus

It is not clear why the variety Taurus, or Hallertau Taurus, has 'Hallertau' in its name when it is not a variety or decendant of the original Hallertau hop. Therefore this variety will only be a subclass of hops:Hops and not a subclass of hops:Hallertau, despite the name of one of its labels.

5. Marketing Hops Examples Using Ontologies

The Hops Ontology's primary focus is on hop cultivars and properties associated with hops. Many of the properties of hops, even those of the same cultivar, may have wildly variable aromas due to growing climates and terroir. The ability to be able to document where and how the hops were grown and processed, not to mention how to interpret lab results, is vital for selling hops. Small scale brewers have more flexibility for experimental beers; however, they have the issue with maintaining consistency in their beers. Therefore, it is imperative that brewers have all the information that they need on the hops so that they can purchase the hops that they are actually searching for.

This ontology is completely OWL/RDFS compliant, references Schema.org and GS1, well known vocabularies and provides examples on how this ontology can be used to provide more information on the product.

5.1 ACME Hopyard Examples

Example 1.1 demonstrates how a fictitious hopyard, ACME Hopyard, sells Cascade Hops.

As seen in the example, the class hops:Hopyard extends the classes schema:Organization, foaf:Organization and gs1:Organization. While this may seem redundant, it allows for a wide variety of vocabularies and standards to be used, as can be seen with the addition of the address. Note that the nodes are named, this is so that fragments could be easily referenced later, which reduces the overall number of lines of code.

The fictional ACME Hopyard has two products: ACME Cascade 2021, Hop Flowers and ACME Cascade 2021, T45 Pellets. In the Hops Ontology, hops:Hops is a crop that is an instance of a cultivar with a brand, name or a common manufacturer. There is no reference to packaging as this represents ACME Hopyard's 2021 harvest of Cascade hops.

Through the usage of the following vocabulary: schema:manufacturer, gs1:brand or gs1:manufacturer or even dcterms:creator, a hop can be related to its parent hopyard. The Hops Ontlogy also has harvestedBy for users who may not want to commit to a formal relationship. This property is easily understood and it can cover most ontological cases.

In order to be sold or traded, hops:Hops must be a Hops:HopsProduct that is contained in some sort of packaging so that it can be easily moved in order to change hands. In Schema.org terms, hops:Hops is a schema:ProductGroup that includes Hops:HopsProduct as variants, schema:hasVariant, of that product. Therefore, hop products can be related to an abstract product of a hop harvest to a discrete, consumable product by relating the Hops:HopsProduct to its packaging through the use of the property gs1:package.

Indeed, should the pelletized cascade hop product be sold by 1lb foil bags, one can define packaging details as an instance of a type of packaging, such as #1lb-foilbag as shown below:

Alternatively, one could simply reference an outside packaging vocabulary. With each new variant of a product, a new instance of Hops:HopsProduct must be created with each new packaging or container.

Example 1.2 Example 1.2 demonstrates how a fictitious hopyard, ACME Best Hops Hopyard, sells Cascade Hops with Schema.org offers.

This example shows the availability of Cascade hops in 2oz Mylar Bags to be sold commercially onsite by ACME Best Hops Hopyard using Schema.org.

Dictionary: hops:AlphaAcids

URI: https://rdf.ag/o/hops#AlphaAcids

None

Alpha acids are of great interest to beer brewers as they are agents that add bittering to the beer when they are isomerized (through the boiling process) to iso-humulons, or iso-alpha acids. Humulone, Cohumulone and adhumulone make up this class of acids. These acids are found in the resin, lupulin, of the hop cone. These chemicals are hexagonal molecules that when non-isomerized are insoluble in aqueous solutions. They are usually expressed in terms of a percentage of the hop's total weight. It remains unclear as to which of the humulones creates the cleanest bitterness in beers, however it is agreed upon that the higher the alpha acid content, the harsher the bitterness in the finished beer. Alpha acids also contribute to foam and bacterial stability as well as reduce beer gushing.

[back to top]

Dictionary: hops:BetaAcids

URI: https://rdf.ag/o/hops#BetaAcids

None

Beta acids, like alpha acids, are found in hop resin. Although only trace amounts survive the brewing process, the ratio of alpha to beta acids are very important to brewers as that ratio determines the decline of the bitterness of hops in storage. When beta acids oxidize, one of compounds that emerges is cohulupulone, which comes from colupulone, does provide some bittering to beer flavor. Once hulupulones are formed, they are relatively stable and can survive the brewing process. Therefore, as alpha acids degrade when they are oxidized during the storage process, bitterness can be recovered as hulupulones formed from oxidation, which is why the alpha to beta acid ratio is so important.

Class: hops:HSI

URI: https://rdf.ag/o/hops#HSI

HSI

HSI is the measurement of the degredation of alpha and beta acids during hop storage and handling. This is useful to brewers as a way to asses the freshness of hops. Through the use of spectrophotometric analysis of the hops the amount of oxidation compounds (absorb light near 275nm) is divided by acids (absorbes light at 325nm) the resulting ratio is the HSI. If the HSI is less than 0.30 it indicates good quality, 0.30 - 0.40 is acceptable quality, and an HSI greater than 0.40 indicates questionable quality. Harvest timing, oxygen, temperature and storage duration are all factors that impact HSI. When properly stored and handled, HSI can remain stable even after a year.

10. General Notes

Data Verbosity, Interoperability and Reasoner

The promise of Resource Description Framework is in two parts: a distributed knowledge graph with url-style identifiers and support for making statements about them. The syntax of the RDF data model has been widely adopted for several applications using different serializations (rdf/xml, json-ld, turtle, etc...), including bibliography, search engine optimization and API integrations. Occasionally, providers will even offer the same data in several serializations using transparent content negotiation to let client libraries choose the optimal serialization.

The promise of RDF with strong knowledge management through standards such as RDF/S, OWL and later SHACL remains to be fully realized as many data providers see RDF as a schema mechanism rather than a knowledge management or ontological one.

The W3 ontologies for time, prov and SOSA/SSN are used as the basis for most terms, the Bibo ontologies for citations / references and the OGC GeoSparql standard is used for spatial data. Other ontologies are referenced on an as-needed basis depending on the domain. Commercially and trade oriented data is recorded using both the schema.org and GS1 vocabularies. Whenever possible, physical measurements are reported in both imperial and metric units using the qudt and/or the obo ontologies.

This ontology is designed to be used as both a fully fledged ontology (in RDF/S and OWL) with complex reasoning capability and a schema-driven dataset for simple querying. As such, it contains a significant amount of redundant information and materialized reflective properties that are designed to maintain compatibility and usefulness in multiple environments. Developers that are used to reading raw RDF statements to locate the relevant information may find it easier to build a query directly from the documentation rather than reading the machine code.

Lastly, while few environments can support OWL at its full capacity, this ontology is useful in the development of applications requiring multilingual labeling, term translation and long term entity identifiers for form generation and reporting.
