Mas Christine (see website) is located 5 minutes drive from Villa Failte ... head towards Le Boulou / St Andre and at the roundabout just past La Decheterie turn right (signposted Mas Christine) and you will come to the vineyard. where you can taste and buy the wine. They speak excellent French and English and are very welcoming and helpful.
Note; the actual vineyards are on the hills overlooking Collioure but this is where the wines are warehoused and sold.
Another vineyard nearby is the better known Chateau Valmy which is the large white house that can be seen on the hillside on the right hand side when driving towards Collioure. Excellent wines there as well.
