Whether you&rsquo;re brewing a 15% ABV <a href="/mead-making/first-gallon-mead-guide">Mead</a>, a sharp <a href="/kombucha-kefir-beverages/kombucha-scoby-health-guide">Kombucha</a>, or monitoring the sugar attenuation in a <a href="/hot-sauce-workshop/fermenting-hot-peppers-comparison">Hot Sauce Mash</a>, you need a way to measure what you can&rsquo;t see: the concentration of dissolved sugar in your liquid. That measurement — <strong>Specific Gravity (SG)</strong> or <strong>Brix</strong> — is the heartbeat of your ferment. It tells you when your yeast are active, when they&rsquo;re stalling, and exactly when fermentation is done.</p>
