Irn bru, dandelion and burdock, and vimto are what I have lying around.
Although if I get round to cleaning the 2,5-dimethoxyphenyl-4-methylnitrostyrene out of my buchner funnel, I might just make myself a filter coffee ( I accidentally broke my coffee percolator pot ages ago via thermal shock. One would think those things should be made from borosilicate glass)
Now I brew my coffee in an erlenmeyer flask over the lab mag stirrer/hotplate, and filter off the grounds using one of my Buchners
Always has to be proper fresh ground coffee for me. I can't fucking stand instant. Cheap and nasty, flavorless piss that stuff. Can't beat freshly brewed REAL coffee, or a fresh, sweet cup of rocket fuel that is turkish coffee though.
