Bright Cellars is a wine subscription service that delivers four new bottles to your doorstep every month. Once you’ve signed up, you will need to take a quiz in order to build your unique taste profile. Each bottle is then selected based on your unique taste profile. The whole idea was created by two MIT grads with a passion for wine, so they created an algorithm that could match potential wines to a person’s preferences based on their answers. They’re so confident that if you’re not matched with a bottle you like, you can always contact them for a free replacement bottle in your next month’s experience.
