98+ Jeb Dunnuck: From the estate’s property in Serralunga d’Alba, the 2017 Barolo Sperss is fresh with pine, perfectly ripe cherry, leather, and aniseed. It has classic Serralunga structure without being imposing, with ripe up-front fruit of dried raspberry as well as tea leaf, and refreshing acidity on the finish. It is layered with depth, but is remarkably drinkable now. This is a beautiful wine to finish out the Gaja lineup. Drink 2022-2042.
96 Wine Advocate - Following so quickly after the celestial 2016 vintage, this Gaja 2017 Barolo Sperss shows muscle and brawn; however, the Conteisa holds its own in terms of aromatic complexity. With fruit from Serralunga d'Alba, that added concentration and determination are expected, especially in a hot and dry vintage such as 2017. Here you get dark cherry fruit with cassis and wild plum. There are also floral aromas that veer toward red rose more than they do violets or blue flowers. And, of course, you get some of those iron-rich or mineral notes of rusty nail or iron that are often associated with Sperss.
