The precious fluid so carefully collected at the Sacraments of Blood would go to waste, had not the church devised a means of preserving and transporting it for later use. The priests and artificers of the Crimson Covenant created the barrel of preserving pine, a cheap but effective tool (see below).
This enchanted barrel perfectly preserves any liquid stored within.
Description: The barrel prevents contamination, fermentation, evaporation, and coagulation. It does not, however, purify any liquids that are already contaminated when placed within. The Blood of Vol sells these items (always through commercial proxies) to various private businesses; they are popular among innkeepers, who use them to preserve various exotic beverages.
Aura/Caster Level: Faint transmutation. CL 1st.
Construction: Craft Wondrous Item, purify food and drink.
Weight: 30 lb.
Price: 500 gp.
