Welp, I’ve been homebrewing for about 2 1/2 years now and just found out about the white labs customer club. Basically, save your empty yeast vials and send them in for some cool swag! Nice way for them to reward your loyal customers. For example, 10 vials will get you a free vial of yeast…. 5,000 vials will get a brew day with Chris White (founder of White Labs). Time to start saving up!
