International Punk Pizza Day (nhatt's birthday)

Not all beers are. There are loads of sites that explain which beers are and which aren't. Just Google for 'vegan beer'.

(Guinness most certainly isn't. Neither is most real ale.)

As with wine. I have a friend who has been veggie (not vegan) for years and doesn't know this. She also doesn't know about rennet in cheese, and scoffs a fair amount of it. I haven't the heart to break it to her.
