Don't forget about Grandpa Spencer's Gourmet Mustards Horseradish Mustard. You will be able to sample it at the Festival too. Grandpa Spencer's Mustards offers three flavors that you will want to try. The Original Sweet & Spicy is like a honey mustard. We have the Hot & Spicy flavor that will sneak up on you and kick to a jalapeno heat. Then there is the Horseradish mustard that is our best selling flavor. Be sure to sample this one! Our web site is www.grandpaspencers.com

You asked… and we listened! 🌶️🎉

Year after year, we’ve heard how much you all wanted horseradish samples — and thanks to JR Kelly Company: The Horseradish House, it’s finally happening!!

Be sure to stop by our FREE grab-and-go sample station located next to the Center Beer Stand and Bloody Mary Stand on Clinton St. 🙌

Come taste the flavor that makes the International Horseradish Festival so unforgettable! 🌶️🔥

Are you a condiment lover? We have three flavors to pick from when you build your cheeseburger. My favorite is the original sweet and spicy. My grandmother created this recipe in 1935 and it quickly became Grandpa's favorite mustard. www.grandpaspencers.com
