I have some lovely Helle and Dunkle beer from Aldi, in 500ml brown glass flip top bottles. Will these be ok to put my Yorkshire bitter into? Its due to be bottled in a few days. I have some old Newky brown bottles salvaged from a friends shed, but they are proving to be extremely hard work to clean, and its much easier to sit and drink a few bottles of this beer.......... with the help of my family. :P I have also bought some nice screw top pet bottles from the homebrew shop.
