Yes, you should be able to taste the Tequila. It is one component of the whole drink.
Is the taste of Tequila over-powering the other flavors? That’s too much.
Is the taste of Tequila absent? That is too little.
Just like a good dish you cook, if all you can taste is the garlic then you have over added garlic. If you can’t taste any you haven’t added enough. And like a good dish, don’t spoil it by making it muddy, no more than 5 distinct flavors so you can taste a little of each with every sip or bite.
