Is your Organic Flour Non-GMO?

All Organic wheat flour produced by Central Milling is Non-GMO. Organic crops must not be genetically engineered in order to be labeled as “Organic.”

Is your Commercial Flour Non-GMO?

All wheat flour produced by Central Milling is Non-GMO. In fact, currently the US has not approved any GMO wheat for sale.

Is your flour bromated?

Never! None of the products made by Central Milling are bromated.

Is your flour enriched?

We make one Enriched Organic flour: Organic Unbleached Enriched. Most of our Red Rose unbleached types of flour are enriched. The best way to know is to check the ingredient label; enriched flours will be labeled as such.

What does it mean if a flour says it is “malted”?

“Malted” means that a very small amount of Organic Malted Barley Flour, Malted Barley Flour, or a natural enzyme has been added to the flour to stabilize fermentation. The ‘Malt’ also helps with coloring in yeast risen products.

Why did you stop stocking your pancake mix at Costco?

Costco moves products between their warehouses to meet their marketing and sales goals. This means they may remove a product from a warehouse temporarily – and without warning. They tell us to tell our customers that it is best to request the product from the Customer Service counter of your favorite store.

Are there any Grocery stores in my area that carry your flour so that I don’t have to pay for shipping?

This is possible but we cannot be 100% sure. Distribution networks are pretty complicated and we are not privy to the customer lists of the distribution companies we sell products to. The best thing to do is to check the store shelves or the bulk bins of your local store(s) and see if the product is made by us. If you are looking for a good All Purpose or Whole Wheat flour, I hear both the organic and conventional versions at Whole Foods and Safeway are truly exceptional (wink wink).

Why is shipping so expensive?

Freight pricing is determined by weight and volume. Unfortunately, our products are heavy which means they are expensive to ship. We do not set these prices, nor do we mark them up in any way.

Do you ship to other countries?

We can. Unfortunately, the cost is typically prohibitive. That being said, we’ve been known to ship flour to Canada and Mexico from time to time. If you’re interested, please give us a call at (707) 778-1073.

Whoops, I made a mistake on my order! What do I do?
