      Antes del lúpulo, la cerveza medieval tenía algo mucho más interesante (y soberano): el Gruut.&lt;br/&gt;&lt;br/&gt;Una mezcla botánica usada para dar amargor, sabor y conservar la cerveza entre los años 700 y 1500. Sin receta fija: cada cervecero usaba lo que crecía en su entorno.&lt;br/&gt;  &lt;br/&gt;Sin embargo, tres plantas eran casi universales:&lt;br/&gt;🌿 Myrica gale (mirto de turbera) → miricetol &#43; flavonoides, actividad antimicrobiana y estimulación leve del SNC&lt;br/&gt;🌿 Achillea millefolium (milenrama) → tujona — sí, el mismo compuesto del absenta — con efectos euforizantes y actividad sobre el SNC&lt;br/&gt;🌿 Ledum palustre (romero silvestre) → ledol y palustrol, sesquiterpenos con efectos narcóticos documentados.&lt;br/&gt;&lt;br/&gt;Combinados con el etanol como vehículo molecular, la biodisponibilidad de todos estos compuestos se dispara.&lt;br/&gt;&lt;br/&gt;¿El resultado? La cerveza de Gruut estaba documentada como euforizante, afrodisíaca y psicotrópica a dosis altas. Muy por encima de su contenido alcohólico.&lt;br/&gt;No era cuestión de sabor. Era química vegetal. &lt;br/&gt;&lt;br/&gt;Al Estado y la Iglesia no le gustó  ¿Personas completamente independientes usando plantas de su entorno para fabricar su propia cerveza en casa? ¡Ni hablar! Esta es la historia de cómo el uso obligatorio del lúpulo, que todos conocemos como ingrediente cervecero, ha llegado hasta nuestros días.&lt;br/&gt;&lt;br/&gt;#nostr #hispanonostr #fitoquimica #ciencia #cerveza #español

      Before hops, medieval Belgium had something far more interesting in its beer: gruut.&lt;br/&gt;&lt;br/&gt;A botanical mixture used to impart bitterness and flavour and to preserve beer between 700 and 1500 AD. There was no set recipe: brewers used whatever grew in the local area. However, three plants were almost universally used:&lt;br/&gt;&lt;br/&gt;🌿 Myrica gale (bog myrtle) → myricetol &#43; flavonoids, antimicrobial activity and mild stimulation of the CNS&lt;br/&gt;🌿 Achillea millefolium (yarrow) → thujone yes, the same compound found in absinthe with euphoric effects and CNS activity&lt;br/&gt;🌿 Ledum palustre (marsh rosemary) → ledol and palustrol, sesquiterpenes with documented narcotic effects&lt;br/&gt;&lt;br/&gt;When combined with ethanol as a molecular carrier, the bioavailability of all these compounds skyrockets.&lt;br/&gt;&lt;br/&gt;The result? Gruit beer was documented as being euphoric, aphrodisiac and psychotropic in higher doses. Far beyond its alcohol content.&lt;br/&gt;&lt;br/&gt;It wasn’t about flavour. It was about plant chemistry. As we shall see, the rulers didn’t like this. Completely independent people using plants from their surroundings to brew their own beer at home? No way! This is the story of how the mandatory use of hops, which we all know as a beer ingredient, has survived to the present day.&lt;br/&gt;&lt;br/&gt;#nostr #grownostr #phytochemistry #science #beer  &lt;br/&gt;&lt;br/&gt;
