Believe it or not, your beer is not vegan friendly.
Most beer is made simply from barley malt, water, hops and yeast -- all vegan approved. But, some breweries use animal products like gelatin and isinglass -- a substance made from fish bladders -- in their filtration process, thus making their product non-vegan.
With Guinness' move towards becoming a vegan-friendly stout, we decided to delve into the world of vegan beer to find the very best on the market.
Note: We used Barnivore, the vegan guide to all things alcohol-related, to verify that the products were truly vegan.
1. Ninkasi

Ninkasi beer is a flavorful, yet balanced beer. For a Ninkasi beginner, their Total Domination IPA is highly recommended -- with a citrusy, floral smell and a bold hop flavor, this is the most popular brew the company has to offer.
Ninkasi founding brewer Jamie Floyd tells Mashable that he chose to create vegan beers in order to retain the flavor and aroma of his brew. He does this by eliminating filters from his brewing process, instead opting for a high velocity centrifuge.
While almost all of Ninkasi's beers are vegan, they did release a coffee milk stout that contains milk fat. It is the only Ninkasi product that is not considered vegan.
2. Flying Dog Brewery
Bloodline Blood Orange Ale smells and tastes like a fresh grapefruit. The citrusy sweetness is balanced nicely by the ale's bitterness to create a refreshing, yet flavorful IPA. Medium-bodied, the blood orange ale has a crisp finish with a pleasing -- albeit long lasting -- aftertaste.
Flying Dog Pearl Necklace, Secret Stash and Table for Two are three of the only non-vegan-friendly brews from the company. You can check whether a beer is vegan friendly on the site prior to purchase.
3. Pilsner Urquell

Arguably one of the most famous pilsners on the market, this earthy beer is hearty in all senses of the word. With hints of honeysuckle and a suspiciously close taste to bread, it's hard to resist this Bohemian brew.
4. Stella Artois

A Belgian brew, Stella Artois was originally brewed for the holidays. But, the beer's light body and crisp, clean finish made it an everyday staple in Europe, Australia and now North America. Stella is perfect for those beer drinkers who are afraid to try a bold brew.
5. Revoultion Brewing
This Belgian-style ale adds a modern twist to the classic pilsner. The wheat beer is lightly spiced with fresh ground coriander and zest from an orange peel. With 5.0% ABV, this beer has a silky smooth finish -- surprising for such a strongly flavored beer. Nevertheless, this golden ale never fails to make beer drinking taste delicious.
Revolution brewing's Mad Cow Milk Stout is the only company beer that is not considered vegan.
6. Ballast Point

If you're looking for a medium-bodied stout, try The Commodore from Ballast Point. Notes of coffee and chocolate can be tasted, but don't overwhelm the flavor of the beer. The light citrus addition provides a light, airy aroma to the stout.
7. Back Forty Beer Company
Back Forty is known for their Southern inspired brews. One of their most popular brews, Naked Pig, is a light pale ale that features 6% alcohol in each bottle. German malts combined with several different hops make this a crisp, flavorful drink for vegan (and craft-beer) newcomers.
The one beer that is not considered vegan friendly from Back Forty is their Truck Stop Honey.
8. Harpoon Brewery

Aside from their Oyster Stout, all Harpoon Brewery beers are considered vegan friendly. Try their UFO White, a spice-filled wheat beer that maintains a balanced citrusy flavor.
Alternatively, the UFO Pumpkin brew is one of the best pumpkin ales on the market. This seasonal beer has a distinctive flavor that comes the closest to drinking pumpkin pie since a PSL.
9. Terrapin

Terrapin's original Rye Pale Ale is available year round -- unlike some of their other popular flavors. According to their website, Terrapin's Rye brew acquires its signature taste by using an exact amount of rye -- a grain not often found in micro-brewed beers. The pale ale features five varieties of hops and several specialty malts to create a bold flavor that overwhelms the senses.
Terrapin beers that are not considered vegan friendly include Gamma Ray, Moo-Hoo and Sun Ray.
10. Trader Joe's brand beer
That's right, TJ's stocks several brand-name vegan beers on their shelves -- including their popular European lagers and pale ales. If you're in a rush, or just want to purchase cheap, but delicious beer, just know that TJ's has you covered.
