Groupon Redemption: Redeeming your Two Bridges Wine Trail Groupon is simple. Please print out the Groupon voucher and bring it with you to each winery. The first winery you visit will redeem the voucher and stamp the paper for you, make sure you carry the paper with you to each additional stop. You will need to make a reservation for your tasting at Wagonhouse Winery; simply email Heather@wagonhousewinery.com. The other two wineries do not require reservations.
