Oxidation is every brewer\u2019s worst enemy. <\/strong>You strive for a stable, flawless beer. You spend time crafting the perfect recipe and invest in the finest hops for an aromatic explosion. Yet, just a few weeks after bottling, disappointment <\/strong>sets in. Your beer loses its shine. It turns dull. Its beautiful fruity notes are replaced by a stale cardboard<\/strong> taste. <\/p>\n\n\n\n

This oxidation phenomenon has happened to all of us\u2026<\/p>\n\n\n\n

While we know the importance of avoiding oxygen intake during Dry Hop, we often overlook that this issue actually begins as soon as the grain is added to the water. So, to preserve the freshness<\/strong> of your recipes, we have developed a decisive tool : Stop Redox<\/strong>.<\/a><\/p>\n\n\n\n

The goal ? To protect your beers right from the mashing stage.<\/p>\n\n\n\n

<\/p>\n\n\n\n


Oxidation Demystified : The threat begins at brewing…<\/h2>\n\n\n\n

To fight oxidation, you need to understand it. The most common mistake is to believe that the danger only appears once the beer is in the fermenter, or worse, in the bottle. The reality is different: the root of the problem lies in your mash tun.<\/p>\n\n\n\n

As soon as you mix your hot water and malts, you create a highly active chemical environment. This environment promotes the formation of what experts call free radicals<\/strong>.<\/p>\n\n\n\n

Imagine free radicals as dormant microscopic saboteurs. They are extremely reactive molecules, formed in large quantities under the effect of heat and dissolved oxygen at the start of the mash. They don\u2019t damage the beer immediately. On the contrary, they act like little time bombs<\/strong>. These molecules attach themselves to the wort chains, waiting for the right moment to activate.<\/p>\n\n\n\n

When these free radicals activate in the presence of oxygen (post-fermentation)<\/strong>, they trigger a cascade of reactions. Even more so when combined with the oxygen sensitivity of hops. They violently attack their aromatic compounds. These radicals are what destroy the desired fruity notes and cause the flavor to degrade into \u201cstale cardboard.\u201d This is why an IPA can be perfect right after fermentation\/carbonation, then fade after just a few days in the bottle.<\/p>\n\n\n\n

The real battle for freshness is therefore not only won by avoiding oxygen intake during transfers. It is won by neutralizing these saboteurs right from the mash<\/strong>.<\/p>\n\n\n\n

Stop Redox : The professional antioxidant accessible to everyone<\/h2>\n\n\n\n

It\u2019s an open secret in the professional brewing world: to guarantee a stable and long-lasting beer, using a method to reduce oxidation during mashing has become essential. These products, derived from the Mash Redox<\/a> concept used by the best breweries, were until now reserved for large-scale production.<\/p>\n\n\n\n

Today, we are making this tool accessible to the homebrewing community under the name Stop Redox. We have repackaged the sulfite-free version of this antioxidant to allow you to bring professional quality into your brews, without compromising the purity of the ingredients.<\/p>\n\n\n\n

But Stop Redox is not an additive !<\/strong> It is a technological brewing aid<\/strong>. It is a highly effective powder that acts as a molecular shield<\/strong> as soon as you add it to the brewing water (before the malts). Even better : Stop Redox is completely eliminated during the boil<\/strong>, ensuring that absolutely nothing of the product remains in your beer.<\/p>\n\n\n\n

<\/p>\n\n\n\n

The double role of Stop Redox :<\/small><\/h3>\n\n\n\n
    \n
  1. Neutralize Free Radicals :<\/strong> It captures the notorious free radicals as soon as they form in the hot wort. By neutralizing them at the source, you remove the key factor that causes accelerated oxidation during the cold phase.<\/li>\n\n\n\n
  2. Preserve Brightness and Aromas :<\/strong> This is the most direct benefit for your IPA. By eliminating these free radicals, Stop Redox allows the complex aromatic compounds of your hops to remain stable. You thus retain the brightness of the colors and, above all, that \u201cwow effect\u201d of fruity freshness right up to the last bottle.<\/li>\n<\/ol>\n\n\n\n

    En agissant pendant l\u2019emp\u00e2tage, Stop Redox cr\u00e9e un filet de s\u00e9curit\u00e9 pour votre bi\u00e8re. C\u2019est la fondation qui garantit la durabilit\u00e9 de votre recette.<\/p>\n\n\n\n

    Attention :<\/strong> bien que cet outil r\u00e9duise drastiquement le risque d\u2019oxydation, il n\u2019\u00e9limine pas la n\u00e9cessit\u00e9 d\u2019une vigilance particuli\u00e8re concernant l\u2019apport d\u2019oxyg\u00e8ne lors du Dry Hop et du conditionnement.<\/p>\n\n\n\n

    The Rolling Beers Advantage : The 30g format, designed for your brew<\/small><\/h3>\n\n\n\n

    We have seen that Stop Redox is a decisive tool. However, while this product already existed in its professional form, its accessibility for the homebrewer was problematic.<\/p>\n\n\n\n

    Historically, the purchase of these technological aids was made in large packages (generally 1 kg). For a brewer producing batches of 20 or 40 liters, one kilo represents years of use. This quantity was far too large, leading to a risk of waste and loss of effectiveness over time.<\/p>\n\n\n\n

    That is why, at Rolling Beers, we decided to make this technology truly practical for you.<\/p>\n\n\n\n

    We have repackaged Stop Redox in a unique 30\u2011gram format. This small package is specifically designed for your reality :<\/p>\n\n\n\n
