Starbucks is launching its instant brew "Via" with a US and Canadian taste test this Friday through Monday! Via has been 20 years in the making and Starbucks is launching it by asking its patrons if they can tell the difference between the fresh brew and instant brew coffee. Whether or not you can tell the difference, you will still be rewarded with a "Thank You" card for a free coffee and a $1 off coupon to purchase Via at any of their Starbucks locations! So, if you are a coffee drinker, why not head in to your nearest Starbucks this weekend to participate in the taste test?! Enjoy your free coffee!
