Casa Maestri Reserva de MFM Aejo Tequila Casa Maestri Reserva de MFM Aejo Tequila is a great sipping tequila. It has a nice aroma, vanilla, caramel and sweet undertones. The smoothness of it goes down so well and makes you want to drink more. You'd think that because it's an Aejo (aged), it would be stronger but that's not the case at all. It is lighter than expected which makes for a great session drinking tequila!
