Anybody here who uses Grolsch bottles for their colour chemistry will appreciate my problem. I am about to change from Agfa C41 and E6 kits to Tetenal, and it's been a while since I did any colour processing, so... I need to get some new colour chemistry storage bottles. They need to be 500ml filled to the brim. And the Grolsch bottles are still the best solution. So, I now need to remove the beer from them, so that I can use them for their proper purpose. Anybody care to help?
