Wizard of wines

The bar tender at the tavern in Vallaki mentioned that their next wine shipment is overdue and that they are running out of wine which could be disasterous for morale.
She has offered payment or free beds if you were to find out what is holding up the shipment and bring the wine to her.
You are planning to go to the winery with the wereravens to take it back fromt the druids.
You have intel that they may be using a staff to control the needle blights but it is uncertain.
Urwin from the keepers of the feather also suspects someone put the druids up to this as they are quite insane and generally keep to Yester Hill (South of the Winery).
