To quote Matthew Jukes: "Raise your glasses, because Andrew Gunn, proprietor of Iona, has finally decided to do the right thing and seal his celestial wine with a screwcap. Iona is now complete. I have followed this wine for years and as each vintage comes and goes it inches towards the perfect score. Now that a cork can't flatten (or indeed ruin) the flavour, we can, for the first time, taste the true, awesome quality of his Sauvignon grapes. Shockingly pure, bracingly dry and aromatically electric, Iona 2005 is a lesson in sheer class. Andrew and Niels Verburg's single-minded, tunnelled-vision, one-mission winemaking completes it brief – to excite, amaze, impress, refresh and satiate the drinker. I can finally say, with conviction, that this is the finest SA Sauvignon I have ever tasted, knowing that you will taste exactly the same unadulterated wine as me, because we now all share the same inert, efficient, precision-made closure."
