A while ago I was told that I should choose my tequilas carefully since ones are meant to be drank on their own(not chased, not mixed) and others (supposedly cause they're lower quality) can and should be mixed. So now that the scope of the site has been changed I feel like I can now ask this here.
So what are the characteristics I should look for in a tequila(other than price) to learn how to differentiate a good-for-drinks tequila from a drink-it-on-its-own one?
