That is pertinently not true, I myself have been drinking Mont Clair for more than 10 years, whether you like it or not is irrelevant now but some 8 years ago those packs were available in 3, 5, and 10 ltr.
For the 5 ltr packs you paid 995 THB, for the 3 ltr around 600 THb. and for the 10 ltr around 1800 Thb.
Now for the past 4 or 5 years, I have been paying 995 THB for those 3 ltr packs and it has remained the same all these years, until today.
It is also still important to pay attention to the alcohol percentage, Mont Clair is 12%, of the wines where the price has been reduced a bit, almost all are wines with a lower alcohol percentage.
That's my referention points!
