I have talked about this before, but I don’t mind mentioning again that preserving wine for the VERY casual wine drinker is hard, it would almost be better to only ever taste a winery’s to ensure that the wine your drinking isn’t to old and that you consume only the amount that you mean to.
Today Woot, mentioned before here has a deal on wine preservation spray, I cannot recommend this as I am not a user of this style of preservation, however if you are maybe the following link will be of interest to you. Remember this is a one deal for one day type of site so if you don’t happen to pick this up today April, 14, 2016 the deal will be gone.
