What matters is obviously per person... So "if you are a couple" is completely irrelevant. Terms like 'light', 'moderate' or 'heavy' drinking are relative and must be taken in context. For instance, historically it has been customary in many countries to drink wine with every meal. So 2 bottles per week is indeed moderate as it's about 1-2 glasses per meal. Likewise, 3.5l a beer per week is one beer at dinner, which is considered quite moderate, indeed. Basically, if your drinking is moderate during meals only and no hard liquor this is considerate 'moderate' to normal in traditional terms.
