Kiwi wine business Invivo has tripled its monthly sales after launching its latest Graham Norton Sauvignon Blanc into Ireland. Invivo is backed by the UK personality, Norton, who owns two per cent of the company and as part of this, produced his own limited edition sauvignon blanc last year. According to co-founder Tim Lightbourne the success of the specialty wine, which was only sold in New Zealand, led to the decision to expand the reach into Norton’s home country of Ireland.
