When we first started hosting fests in 2003, we used hard plastic cups due to venue restrictions and safety concerns with using glassware. Our original cups were great, but very expensive, not recyclable, used a lot of wasteful packing and storing them took up a ton of space. So years ago we switched to PLA (Poly Lactic Acid; plastic made from corn) bio-compostable cups. They've been working great for us from a logistics and financial point of view, however, their lack of a clear 2oz pour line caused confusion. We did look into printing one, but it wasn't feasible due to minimum quantities, storage limitations and other restrictions with the manufacture. And more importantly, over the years we've received a growing number of complaints about them from attendees who want something more durable, collectable and respectable. Your feedback has been heard. As of our Microbrew Invitational this June 3 + 4 in Boston, we'll be trying out 10oz ultra-thin, flexible, BPA-free polymer, shatterproof, reusable and recyclable drinkware from govino. It features our Microbrew Invitational logo and a clear 2oz pour line to adhere to Mass. state law, plus they look a lot like a glass, feel good in hand, have a thumb notch and don't impact the color, aroma or flavor of the beer. We went with 10oz as it leaves plenty of room for head/frothy pours and it's currently their smallest size for the type of drinkware that we were looking for. Looking forward to seeing these in action, and hearing attendee feedback. Cheers!
