USA: Prosecco still growing, but no longer double-digit

Prosecco is still growing in the US, but at a slower pace than in the recent past. In 2017, 5.5 million cases were shipped to America, + 5% on 2016, which, for the first time in the last 5 years, did not reach a double-digit number. It is still substantial growth, but slower, as the channels IRI (the American company) monitor reveal: Prosecco grew 30% in 2016, 17% in 2017 and now 11%, in the last 24 weeks anyway (closed March 24th). What are the top brands? According to Impact Databank of the Shanken group, they are La Marca, Mionetto, Cupcake, Zonin and Lunetta (by Cavit, https://goo.gl/Uic3DY).
