This Vineyard is a big joke! You don't get to test anything for free. Well, nothing is for free actually. They even charge for using the restrooms. Besides, everything is costly here. I got cuppa coffee at the cafeteria which had costed me 40 bahts and then I threw it away after the first sip 'cos it was disgusting. They obviously use their scenery for tourist attraction to make money on. Nothing more... If I were you, I'd only stop-by to snap a few photos.
