Bodegas Muga is the only winery left in Spain that uses only oak throughout the entire process of elaboration of their wines. Muga has its own cooperage and directly importing American and French oak makes this possible. The winery manufactures about 2,000 barrels each year. The wine is racked every four months by gravity and the use of candle to detect sediment. Fining is done by egg whites. The process takes over two months as the raft of egg whites sink to the bottom of the vat. This is a very expensive technique, but it succeeds in giving Muga reds a distinctive velvety texture.
