For all intents and purposes, it wasn't really. But because parts of fish were being used even as a filter, Guinness couldn't be considered vegetarian-friendly. (Video via Guinness)

Guinness told Time a state-of-the-art filtration system will replace isinglass sometime in 2016. (Video via Guinness)

Vegans and vegetarians have been petitioning the company for a while now, and for the first time in 256 years, Guinness is making the change to its process. 

But will the change affect the taste? It shouldn't. The isinglass is reportedly used to help the yeast settle faster, so it shouldn't have much of an impact, if any, on taste. (Video via Guinness)

With the beer soon being vegan-friendly, many more people will have a chance to taste for themselves.
