Hi,can you help with a problem I have please.I keep my barrel in the conservetory and knowing that today will be quite warm I filled up two flip top bottles from the keg last night and put them in the fridge to cool for drinking today..however the beer in the keg has plenty of gas and keeps its head but...the bottles in the fridge were as flat as a pancake...orrid.When I used to make beer in the past I always did this and the results were perfect..any ideas...thank you..Filbs.
