Cheap, drinkable wine in Thailand

Not much of a wine drinker, expensive bottle of plonk would be wasted on me anyway. But don't mind a few glasses when we go camping. Recently tried that Laughing bird, heard it was cheap and cheerful and it is. Have a purple label (reserve) and red bottle (normal). I got the purple bottle thinking it might be better. Like all cheap reds first few sips rough but after not bad. I was wondering if the red label a little less dry and maybe a bit sweeter? What is the difference between the two?

Can anyone recommend a cheap and cheerful White wine? (Not Spy lol)  Something a bit sweeter, not too dry...even sparkling. Mrs not keen on the red. Something available anywhere....Lotus etc
