Wow!!

"Best GF bread hands down. And Canadian!!! A win-win!"

Calvin K. (5/5)

Delicious Bread

"These loaves are absolutely incredible! They're not too dense and full of flavour. So far, I've only used this product as toast - I'm sure there are many more inventive uses. I'm sold on Queen St. products. One happy customer!"

Sean S. (5/5)

Enjoy

"I am enjoying the super grain sourdough bread. I am happy with the ingredients. There are NO ingredients that one are known what they are. The size of 1 slice is on the smaller size."

Patrick K. (5/5)

Wonderful

"The bread tastes great. Needs to be toasted which isn't a big deal. The slices are kinda small. I purchased online direct then went shopping on another site and they were selling for much cheaper. I hope to purchase more on the future. Usually I buy carbonaut but this is quality stuff."

john p. (4/5)

Great customer service!

"I had a small issue with two of the five bags of sourdough bread I purchased. Nothing wrong with the product but an issue with packaging. Queen Street bakery representative contacted me almost immediately and went ahead and sent out another order to help resolve my issue. Thanks you!"

Norman C. (4/5)

Good but….

"Before I start this review I wanted to say that Queen Street Bakery products are MY MOST FAVOURITE gluten free breads! I was excited to try the sourdough line. The taste is exceptional but it’s not agreeing with me. Please don’t make my review deter your choice. They the sourdough. Is so soft and so hearty! It’s jus not agreeing with me"

Rose S. (3/5)

Great gluten free sourdough

"I love the bread. It's so hard to find gluten free sourdough so I am grateful that you guys make it. The only thing is that I wish it was all organic ingredients."

Tania H. (5/5)
