    The world of hops

    How do you determine what to replace one or another hop in beer with?

    How do you determine what to replace one or another hop in beer with?

    Hops play an important role in beer – they provide not only bitterness, but also aroma and flavor. Here's how to identify suitable substitutions for various hops, depending on their properties and purpose: aroma hops, bittering hops, or others.

    1. Malting hops and their replacement

    • Alpha Acid (AA) Content: Bitter hops have a high alpha acid content, which is what determines the bitterness of the beer. It is important to select hops with similar AA levels for replacement.
      For example: If the original hops have 10% AA and the selected replacement hops have 5%, you will need twice as many.
    • Popular bittering hops:

    Magnum is a versatile and intensely bitter hop.

    Chinook – provides both bitterness and subtle spice

    Substitution formula: By adjusting the amount used, the desired bitterness level in the beer can be accurately recreated.

    2. Aromatic hops and their replacement


    Aromatic profile: Aromatic hops are often used at the end of brewing or for dry hopping to impart fruity, citrus, or floral aromas to the beer. The change requires careful analysis of the aroma profile.

    Popular aromatic hops:

    Cascade: Citrus and floral aroma, ideal for Pale Ale style beers.

    Citra: Tropical fruits and citrus, often used in IPA styles.

    Substitutes:

    Cascade can be replaced with Centennial , which also has a floral and citrus aroma.

    Citra is often replaced with Simcoe or Mosaic , which have similar tropical accents.

    3. Hops in beer and style traditions


    Style maintenance: Hops in beer are often associated with certain beer styles. For example, German hops such as Hallertau Mittelfrüh are typical of lagers, while English hops such as Fuggle are used in English ales. Regional substitutions: If the original hops are not readily available, substitutes from the same country of origin can be used. For example, Saaz can be substituted for Tettnang , as both come from the same country and are used to make traditional lagers.

    4. The purpose of hops in beer production

    Hops are used in beer for three main purposes:

    Bitter hops: Used at the beginning of the brew to create bitterness.

    Aromatic hops: Added at the end of the boil or during fermentation to produce a subtle aroma.

    Dry hopping hops: Used at the end of fermentation or after fermentation to enhance aroma.

    When choosing substitutes, it is important to understand what function hops play in a particular recipe.

    For those interested in hops

    If you are just starting to learn about hops and their role in beer brewing, it is a good idea to start with a clear and beginner-friendly literature. Hops are one of the main ingredients in beer, giving it its bitterness, flavor, and aroma. Here are some books and resources that can help:

    How to Brew - John Palmer
    This is a great guide for beginners in brewing. The book clearly explains how hops work, what types they are, and how to use them to create different flavors in beer.
    Where to find it: You can purchase it online on sites like Amazon or through specialty brewing stores.

    For the Love of Hops - Stan Hieronymus
    This book is for those who want to understand the world of hops in more depth. It discusses the chemistry of hops, how they are grown, and how different types affect the flavor of beer. The book also provides lots of practical advice on using hops in beer styles.
    Where to find: This book can be found online or in specialty bookstores geared toward brewing enthusiasts.

    Internet resources and forums

    • Brewers Association (brewersassociation.org): Provides a lot of information about hop types and their properties.
    • Homebrew Talk (homebrewtalk.com): A community where you can ask questions and learn more from other brewers.
    Hop storage

    In order for hops to retain their properties for as long as possible at home, it is important to follow proper storage conditions. Hops are sensitive to oxygen, light, heat and moisture, so the following rules will help ensure their quality:

    Cold storage

    • Refrigerator: Hops should be stored in the refrigerator if you plan to use them within the next few months. The cold helps preserve their aroma and alpha acid content.
    • Freezer: For longer storage, it is best to store hops in the freezer. The low temperature slows down the oxidation process and extends the shelf life of the hops.

    Oxygen safety

    • Hops are sensitive to oxygen, which can destroy their aromatic properties and reduce the effectiveness of alpha acids. Therefore:

    Vacuum packaging: Use vacuum bags to remove air and reduce the risk of oxidation.

    Airtight containers: If you don't have vacuum equipment, use airtight containers or bags with a zip-lock zipper.

    Protection from light

    • Darkness: Hops should be stored in a dark place or in opaque containers, as light can destroy their aromatic oils and cause chemical reactions that degrade the flavor.

    If you want to check if the hops are still of good quality, smell is the best indicator. If the hops have a pungent or stale herbal smell, they may not be suitable for use.

    For longer storage and better preservation, nitrogen or other inert gas fillers can be used in vacuum packaging, but this is most commonly used in commercial settings.
