No, you could say, 'Oh just one would be fine, as I'm not drinking much at the moment'.
But if he gives you three anyway, so what? Put it away! He doesn't expect you to sit down and drink three bottles right off.
Open one, take a very small glassful so you can honestly say something about it, and let your husband finish it over the next 2-3 days.
What really is the problem?
