That is how I would express this thought. I am quite sure that no one would ever notice any oddity about this sentence in real life, no matter how many variations are at least conceivable.
Possibly a more informal expression would be "can you tell" rather than "can you taste" or "can you identify."
-- "Can you tell which is which by tasting gin and vodka?"
An alternate way of asking the same question could be:
"Can you taste the difference between gin and vodka?" or
"Can you tell the difference between gin and vodka?"
The words "gin" and "vodka" should not begin with upper-case letters.
