A gin is more likely to be made from fermented and distilled apple base spirit than it is to include apple as a botanical; however in recent years we’ve seen some distillers begin playing with apple as a botanical.
Nearly a hundred million tonnes of apples are produced worldwide each year. The trees they grow on are botanically related to roses. Flavorwise, they range from the stark, acidic, and slightly green tasting Granny Smith, to apples which taste incredibly sweet. There’s a wide range of expression apple can take on in gins depending on the cultivar chosen.
