Keg of bee’s knees has been filled to max.
Unlike honey mead must, bee’s knees can be made with one serving of forest honey which is more economical. You can get 5 servings of forest honey from two honey combs, unlike spiced mead must which either needs two honey combs or 10 forest honey, so it’s a waste to craft it with the latter.
That said, spiced mead is much better in terms of value. Spiced mead’s nutrition/quench/enjoyability is 4/14/14, while bee’s knees is 7/25/20. While the numbers for the latter is better than the former, there’s still a matter of servings. With a large waterskin, you can fill it with 20 servings of bee’s knees, while if you fill it with spiced mead instead you get 140 servings.
There’s also a matter of crafting ingredients. Forest honey is somewhat rare, and so are honey combs. The other ingredients for spiced mead must are easy enough to gather, while lemonade can be somewhat hard to find (though you can get some from MREs, I think) and gin is an uncraftable liquor.
Surprisingly, spiced mead and bee’s knees has no negative health impact (not counting the hallucinations and shakes from drinking too much). And strawberry surprise is actually healthy. And boozeberry has a higher addiction.
