I know this thread is old, but maybe someone can use these:
1) "Vineyard's Unending Bounty" is a Wineskin of holding
This wineskin appears to be a normal item of its type. It's magic becomes apparent when the owner tries to fill it. Like a bag of holding, the liquid placed in the skin goes to an exra-dimensional space. This one-gallon skin can hold up to 10 gallons of water, wine, beer, or other liquid.
2) "Alcohol Anytime" is an Everfull Mug (modified)
This mug has 100 slots. When a new liquid is poured into the mug and consumed, it takes up the next empty slot.
On command (free action) the mug will fill (1 round) with the commanded liquid (assuming it is on the list), which can be referenced by name or number.
Sixty seconds after a liquid leaves the mug, it becomes normal water (thus preventing selling it).
-->Note that while the imbiber *tastes* the alcohol, it turns to water before it can have any real effect!
-->This item is to be used in an upcoming campaign, given to the "Drunken" monk by his superiors without telling him the water part, who want to show him that his abilities are his own, not the product of alcohol consumption.
