1. Look out for that mid-priced wine you’ve never heard of.
The cheapest wines are probably not that great. The most expensive are, well, expensive. The best value for money is often the mid-priced wine that isn’t a familiar name. That’s usually the darling of the sommelier.
 
2. Ask what differentiates wines within the same price range.
There might be an underlying logic to the wine list, particularly if it isn’t arranged by price—a good sign. Ask your waiter about how the list is organized. For example, the wines might be ordered from light to strong.  If two wines are the same price, ask how they’re different.
 
3. Don’t buy the big-name Champagnes.
Most independent Champagne vineyards sell to big producers like Moët and Veuve Clicquot. But some guys also bottle their own wines, meaning it’s 20 percent cheaper for the same thing as the big names. It’s harder to find here in Thailand, but when you do find obscure Champagne, go for it.

1. Start with the right restaurant.
Look for a passionate owner or somewhere with a sommelier who knows how to select, procure and explain each bottle. Also, many independent restaurants [those located outside hotels] have moved away from a cost percentage and are instead charging a variable flat fee per bottle. This means you can find greater value in these outlets. 
 
2. Go for unfamiliar grape varietals.
Traditionally, the house wine offers the best value, but this is not always true in Thailand due to taxes and duties. At a lower price point, innovative winemakers can create liquid gems from grapes you’ve never heard of.
 
3. Do the math.
Take into account the region, vintage and price of the bottle to work out for yourself which offers the best value.

1. Look for lists that categorize wines by characteristics.
It’s been done this way for 10 years in Napa Valley. Bangkok just started two years ago. Categorizing wines by country, region and vintage is not very helpful to the general public; in fact, it’s quite outdated. 
 
2. Ask the sommelier.
It sounds obvious. Great sommeliers want to please their guests, and the ones with extra attention to detail will actually try their best to pair wine with the flavor profiles in the food that you are eating, instead of trying to force you to buy more expensive wines.
 
3. Keep an open mind.
There are so many nice wines with your desired character that you may not have heard of. If you want to expand your wine exploration, ignore the most expensive and the cheapest wines on the list, because they tend to disappoint.
