I buy three 5 litre casks at a time brought from Mendoza by my local shop owner. Usually a mixture of Malec,Tempranillo and Syrah. I uncork one at a time and decant into 6 bottles. Cost for 5 litres is 80 pesos which is tremendous value considering the quality. A weaker man than I could easily become an alcoholic here.
He brings some decent oporto and olives as well.
