Introducing King Arthur’s guide to sustainable baking
It's a hub for all the planet-positive steps bakers can take.

When it comes to making better decisions for the planet, there is at least one heartening truth: We have no shortage of options. Whether it’s regarding our coffee, our commute, or our crumb cake, we’re almost always given the opportunity to choose a better path. Sometimes it’s a path of less — less carbon, less waste, less water usage. Other times it’s a path of more — more impact, more responsible land stewardship, more responsible treatment of workers.
Having many paths doesn’t, unfortunately, make it easy to pick one. In fact, picking just one is a cause for anxiety. As some climate researchers like to say, we no longer have the luxury of choosing just one path. We need to go down all paths, and take all the options that are available to us.
Every ingredient swap, every instance of avoiding excess food waste, is a step toward sustainability.
As a company, King Arthur is doing just that. On a corporate level, we’re leaning into regenerative and organic wheat, examining our packaging, and thinking about how our business can heal not just the planet but also the people living on it. (Expect to hear more about these efforts in the coming months.) And on the individual baker level, we’re thinking deeply about the paths to sustainability we might forge in our homes.
After all, the kitchen is a resource-heavy room. It’s a place where we use lots of water and burn lots of gas. And, of course, it’s the room where we put all our various food choices to use. Thus the decisions we make in this realm can have an enormous impact on our own personal environmental footprints.
Which is why we created the King Arthur Sustainable Baking Guide. Everyday bakers may struggle to find impactful changes they can make in their baking, so beginning now, and continuing every month, we’ll offer advice (and recipes!) for baking with a smaller footprint. This advice will be full of all the positive steps bakers can take: suggestions on how to use less single-use plastic, for instance, or tips on making the most efficient use of your oven.
We’ll also look at ingredients. Perhaps the most proactive step a baker can take is selecting planet-positive options like rye flour and regeneratively-grown wheat. At the same time, it’s hard to bake without butter, cream, and eggs — just a few of the foods that can have significant environmental impacts. So: Is local dairy better for the planet than commodity dairy? Is vegan brioche truly possible? These are the questions we ask ourselves as bakers, and now we’ll ask (and answer) them in public.
Sometimes the tips we share will feel small. We know that. If one baker washes their parchment paper so that they may use it again instead of buying more (and yes, you can do that — more on that soon!), we have to ask ourselves: Has that baker really made an impact?
Our answer to that question is yes. Because while it’s admittedly daunting, and maybe even misguided, to think that such changes can tackle the real problems facing our planet, we nevertheless believe that bakers can make an impact at home. And we can at the same time acknowledge that there are limits to our individual actions. One does not necessarily discount the former.
In other words, even the baking decisions matter, and rather than label them “small,” it serves all of us to think of them as simply cumulative. Every ingredient swap, every instance of avoiding excess food waste, is a step toward sustainability. The next action, and the next, and the next, only widen the impact a baker makes. The key is to find the actions to take and to take them often. The launch of our Sustainable Baking Guide aims to help you do just that.

Count me in as opposed to the additional fungal alpha-amylase 'enzyme' in your products.
October 25, 2024 at 11:57am
I have been making sourdough bread for over a year now and my breads have been failing for two weeks now and nothing has changed. I have heard you added a enzyme now, so that's the only thing that has changed. I have 15 pounds of the bread flour and I guess I'm going to have to change the flour to see if my bread improves. I'm so disappointed about this matter.

In reply to I have been making sourdough… by Laura G Lees (not verified)
Hi Laura, adding an enzyme to our flour actually helps ensure that our flour performs more consistently from one year to the next (since enzyme levels in wheat can vary from one crop to the next). We used to add malted barley to correct for enzyme activity because it is also a source of enzymes, but found that the level and efficacy of those enzymes can vary just a smidge from batch to batch. The activity of straight enzymes varies less, so using them creates an even more consistent flour. Also, the process of malting barley is very water and energy intensive, and we were looking for alternatives.
It's extremely unlikely that the enzyme we add is causing your bread failures. A more likely cause of your recent issues may be related to the change in seasons. Around this time of year, when your home is likely cooler than it was over the summer, your sourdough starter and bread are likely to rise much more slowly. For help achieving more consistent results, check out our Desired Dough Temperature blog post. For more help troubleshooting, please don't hesitate to call our Baker's Hotline at 855-371-BAKE (2253). We're here M-F from 9am-7pm EST, and Saturday and Sunday from 9am-5pm EST. We'd love to help you figure out what's going on with your sourdough bread!

Hi Laura, I agree with the KA response below and believe the added enzyme does not effect my sourdough bread making, I've been using their flour for over 10 years now. But I would think the difference in humidity and temperature in your kitchen has more to do with your success. Where I live I often add 10%-15% more water to my mixture in the winter vs. the summer. Also agreeing with their replied, the proofing of the dough takes much longer at lower temperatures. Good luck, John

Is your flour fair trade? Ethically sourced?

In reply to Is your flour fair trade?… by Reagan (not verified)
Hi Reagan! Yes, the wheat used for our flour is grown and milled in the United States and the growers of this wheat are paid at least a fair market price for their crop and the growing, milling packaging and all other aspects of the production of the wheat/flour does not involve any humanitarian labor issues. Happy baking!

Do you use glyphosate on your wheat? I feel that gluten intolerance is directly related to this and am trying to find a company that doesn't use this.

In reply to Do you use glyphosate on… by Jennifer Pereira (not verified)
Thanks for getting in touch with your question, Jennifer.
Understanding your preference is to avoid the possibility of glyphosate application, we recommend choosing from our full line of certified 100% organic flours, where its use is prohibited.
We offer our organic line to ensure that our customers have options to suit their individual needs. Our organic flour line is independently verified by QAI (Quality Assurance International) to ensure organic certification requirements are strictly followed.

In reply to Thanks for getting in touch… by jcloutier
This thread is almost two years old; however, there is a new concern that has recently surfaced with King Arthur's unfortunate decision to put a fungal alpha-amylase 'enzyme' in ORGANIC bread flour and AP flour. I cannot tell you how many of us that choose ORGANIC for valid reasons are absolutely lived that you have tainted ORGANIC flour with a lab-made additive. Any flour that has an additive in it is NO LONGER CONSIDERED ORGANIC. I have been a lifelong customer of King Arthur Flour and it's very sad and disheartening that you, of all companies, would do this, specifically in the times we live in where our food is being poisoned on so many levels and in so many ways.
Organic flour should be pure, certified organic milled wheat and NOTHING else.

In reply to This thread is almost two… by Sharon R. (not verified)
Hi Sharon, thanks for sharing your thoughts on our transition from the use malted barley flour to this enzyme in our flour. Enzymes have been used in food products for over 40 years to to help create nutrition in flour for feeding yeasts. Adding enzymes results in improved bread volume and crumb texture in baked goods, and we're excited to be able to offer a more consistent and sustainable product to our customers. We can also assure you that the addition of the enzyme (which is a natural product) does not influence the Organic Certification of our flour.
Of course, choosing what you cook with and eat is an extremely personal choice, and we would never presume to tell someone what they should or should not use. If you have any questions about this ingredient, or our products, we're happy to help!
