I recently hired Vine Capital for investment purposes and found them really useful. To be honest i havent looked too much at the competition out there in terms of wine investment brokers or merchants. But i dealt with a guy called Andrew Hart and everything went smoothly in terms of business for me. Not sure how big their team is either im affraid.
Im thinking of using them again. Did you end up taking the post there?
