  • How alcohol rewires your brain

    Alcohol doesn’t just make you tipsy—it rewires your brain chemistry in real time. It slows your brain with GABA, spikes dopamine to make you feel unstoppable, and blocks glutamate so you can’t form memories. That mix explains everything from slurred speech to blackouts … and brutal hangovers.

  • A quick guide to rosé wine

    What is a rosé? Rosé wines are technically reds, though they’re typically served cold and have more flavor characteristics in common with white wines. This primer explains the basics of the fastest-growing wine category in the US. It covers production and rosé-making regions and styles, along with some common tasting notes for each bottle.

  • How fermentation works

    Alcoholic fermentation is the process where yeast transforms grape sugars into ethanol, creating wine. Microscopic fungi (commonly known as yeast) metabolize sugars, producing alcohol and carbon dioxide. Fermentation's speed and temperature impact wine's flavor and style: cooler temps suit fruity whites, while warmer ones enhance red's tannins. Fermentation stops when sugars are depleted or by temperature extremes, and sometimes yeast removal yields sweeter wines. Get a quick breakdown of the process with this easy explainer.

  • There's a legal loophole behind California Champagne

    In the late 19th century, sparkling wine production took root in California before France began the fight to own the term “Champagne.” Many American winemakers already used it for easy recognition. The battle continued for over a century before reaching an agreement in 2005, stipulating American sparkling wine couldn’t be labeled as Champagne unless the producer was already calling it such.
