We've known what wine is for centuries, but a more modern challenge is wine fraud, which has only become more sophisticated. It can refer to the meddling or making changes to a cheaper wine to make it taste more expensive. Such as using an additive to create a ‘vintage’ wine feel in both taste and appearance to fool the prospective buyer. Essentially if you’ve bought a wine that’s been sold based on false attributes and qualities — whether it be brand, taste, vintage, location, or price, then it’s considered fraud.
