Not 100% positive but ive been told by some stores that you can only get canebreak in bottles around lafayette.
This. The demand in lafayette is so high, that they can't keep up production for bottles in other markets. So Lafayette gets first crack.
Also, there is a chance that another shipment of Grand Reserve will be coming out today. Here in BR, i believe Cuban Liquor may be getting some more, from what they told me last sunday.
