I want to make a purple beer. Long story short, its for a charity event and the official color for the charity at issue (pancreatic cancer) is purple. The beer is going to be a belgian wit. Not everyone is into beer. However, this seems to be the most universally drinkable beer, at least from my own experiences.
I was thinking about just brewing it normally and then adding in some purple food coloring into the bottling bucket, along with the priming sugar.
1. Is there any type of food coloring I should use?
2. Any thoughts/ideas on when I should add the food coloring? The bottling stage? Secondary fermentation?
3. As well, any thoughts/ideas on whether food coloring would affect the taste of the final product?
