Franzi Grab and Lex Thomson own a vineyard on Kaituna-Tuamarina Road on the northern bank of the Wairau River. They have 4 ha of Sauvignon Blanc, planted in 2008 and 2009 but also, interestingly, 1,000 Arneis vines, planted in 2008 and 2009 after being impressed with the variety while travelling in Piedmont. The vineyard is tended by both Franzi and Lex, who are trained viticulturists and winemakers, the vineyard certified BioGro organic in 2014. I have reviewed the Tua Marina Arneis from the 2014 vintage. The wine is made carefully with subtle inputs, and shows consistency of style. Here is my review of the 2017, from according to Franzi, a difficult harvest which required intensive vineyard work and strict fruit selection to ensure only healthy and ripe fruit was employed. A lighter and more delicate wine has resulted, but one that has typical varietal characteristics. www.tuamarinavineyards.co.nz
