Promising review: "I'm always trying to find fun, different gifts for my husband. He is a gin man, and has also brewed his own beer, so I picked the gin kit as a gift for his birthday. He loved it!! He had a good time putting it all together, and was extremely thrilled with the end result. He wants to get the refil pack so he can make more. Great gift for anyone that likes to be part of the process to enjoying the finished product!" —Satisfied Customer
