You’ve likely been introduced to regular Thompson Seedless Grapes—but have you met their Sweet Baby siblings? If not, we’re here to make the introduction! Sweet Baby Thompsons are essentially regular Thompsons that have grown on ungirdled grapevines. Girdling is the practice of carving out a thin ring of bark around the main vine trunk, effectively preventing water and nutrients from traveling back down the plant to the roots—while still allowing water to rise from the roots to the fruit, up through the center artery of the tree. Girdled vines cause grapes to retain more water, producing larger, less sweet fruit. But since Sweet Baby Thompsons grow as nature intended on uncut vines (probably why this variety is also called “Natural Thompson Grapes”), they don’t swell as much with excess water, thus remaining smaller—and also wonderfully sweet!
