Yes, we didn't have time to add too many drinks, though there are over 46 of them. In the remake we'll have at least 200, though -- so it will be much easier to create drinks. Here's a tip: Use only one or two ingredients. If you use just one ingredient to make a drink you've got about a 50% chance of succeeding, and with two ingredients you've got about 2%. However, if you use combinations that could realistically exist (like coffee + sugar, not green tea + pineapple) then you get up to about 30-40% chance.
