Found my keg of Wherry leaking today from the tap on this Wilko keg, so I tighten it up slightly and I also pulled a glass of the brew.I did this as I felt the pressure in the barrel was too much. The brew had a fantastic head, slightly cloudy, with quite a good taste. The beer has only been in the keg for a week conditioning, with me taking a glass out of the keg, will I be OK in leaving it a further week or two before I start to drink it. Or will taking some out of the keg shorten the life of beer?
