Four Friends Brewing is vegan friendly

Company email (August 2013):
"Thank you for reaching out to our small hometown brewery. We do NOT use any animal by products in the creation/production/processing/packaging of our beers. Our use of finings to settle yeast particulates is strictly constrained to the use of NON animal derived products, specifically we use NALGENE which is a Si2C03 acid. While our beers are not specifically designed as Vegan products, we strive to be as vegan friendly as possible."
