Baby Bastille!

The origins of Castile soap go back to Middle East, where Syrian soap-makers have made bar soap based on olive and laurel oil for a thousand years.  It is commonly believed that the Crusaders brought Aleppo soap back to Europe in the 11th century, based on the claim that the earliest soap made in Europe was just after the Crusades, but in fact the Romans knew about soap in the first century CE and soap making was described as early as 300 CE.  Following the Crusades, production of this soap extended to the whole Mediterranean area. Early soap-makers in Europe did not have easy access to laurel oil and therefore dropped it from their formulations, thereby creating an olive-oil soap now known as Castile soap.  Bastille soap must be 70% olive oil with other oils added for various reasons.  Our Baby Bastille soap is 95% olive oil and 5% castor oil.  Castor oil adds fabulous moisturizing qualities and a dense creamy and stable lather.  Click to shop

A Big Thank You

Avery Brewing has supported Flatirons Soap Works from our very beginnings.  True entrepreneurs, they gave us a chance, early on in our journey, to make soap for their taproom.  We are preparing a new order for them the first week of January.  For the first time in our history with them, they gave us a chance to create a soap from their premiere brew, The Reverend!

In addition to The Reverend, Hog Heaven will be arriving at Avery the first week of January.  Stop in and have a meal, a beer and take home a bar or two of soap!

Why Use Beer Soap?

You may think that beer soap is merely a gimmick, but soap makers have been making soap for many years – even before the huge popularity of Craft Beer.  There is a very sound reason to use beer soap.  Not only is beer soap is silky soft and produce thick beautiful lather, beer soap is so very good for your skin.

Our New Favorite!

Moon Over Colorado!  We finally figured out how to make a Colorado Soap!  Using a Colorado Original Brew, we created a soap in response to numerous requests.  Making a Cold Process Soap with a large embed is a somewhat complicated process. As with all cold process soaps, the end result is a gift from the “soap gods.”  We have made about 4 batches and cannot keep it on hand!  We had a large supply going into the Christmas season but sadly they sold out very quickly and we have 32 bars curing now.

Long time gone!

Its been half a year since I wrote last! So much has happened in that time out! From the Bacon and Beer fest we were selected to be the only soap vendor at The Great American Beer Fest.  We went into overdrive because the GABF is 65,000 attendees!  We had to make soap and make soap and make soap!  From there we slipped into autumn and on to Christmas! We have finished all of our Christmas Shows and now are closed until mid-January.

A New Adventure for FSW!

Today we set up our mini-shop in a new space at Cherry Creek Mall (Denver) called The District Shops.  This is a space for hand crafted items created by artisans from the greater Denver area.  FSW will be located on the Main Floor –  The Marketplace!  This area will be broken into 5 “Districts”.  Each district will have a unique background, unique look, and unique products.  Districts include Food District, Vintage District, Boutique District, 5280 District (Colorado products), Little District (Kids products), Spa District, and Gentlemen’s District.  FSW will feature all of our gentlemen’s products, beer soaps and little gentlemen’s products.  This is our first foray into a brick and mortar enclosure.  As you are probably aware, we have our Shopify web page and we participate in many weekend shows, but now we will have a permanent outlet for many of our products!

The District Shops will open officially on June 1.  Please drop into this new facility inside the Cherry Creek Mall and check out our products and other products created by our fellow Colorado artisans


Bacon and Beer Classic – Mile High Stadium

In mid May, FSW is attending the Bacon and Beer Classic at Mile High Stadium.  We are so honored to be one of a very few vendors (non-brewery or non-restaurant) invited to attend.

This event has given us an opportunity to collaborate with brewers who are participating to create soaps from their best-selling beers and from the beers they are highlighting at this event!

Our most exciting collaboration is with Breckenridge Brewery of Littleton, Colorado.  They have worked with us to create the signature soap for the event.  We have created a soap from the beer Breckenridge  is featuring, Vanilla Porter, and their Farm House Restaurant, furnished us with lard from the bacon being featured.  We had the most fun creating a soap that will be fabulous, mild and moisturizing using these ingredients!  We haven’t forgotten about our vegetarian and vegan friends, we created a Vanilla Porter Soap with all vegetable oils too!  The little pig peeking out from the soap indicates the lard soap.



Our staunchest supporter, Avery Brewing Company, has collaborated with FSW since our very first year.  The loyalty and support of the great folks at Avery have been so inspiring.  Over the course of collaboration, we have created so many beer soaps, El Gose, Vanilla Bean Stout, Out of Bounds Stout, Raspberry Sour, Coconut Porter, White Rascal, Liliko’i Kepolo, Real Peel, Tangerine Quad, Apricot Sour, Perzik Saison, Chai High and Rumpkin!



Kokopelli Beer Company of Westminster, Colorado has trusted us with several of their best brews and we have created fun soaps to complement their fabulous brew list.  Razzmataz, Berryana, Blarney Stone, Day of the Dead and All About Spice



Left Hand Brewing Company of Longmont, Colorado gave FSW a chance to produce soaps for their top of the line brews, Milk Stout and Juicy Goodness!



Another Brewery we collaborated with for this event is Odyssey Beerwerks of Arvada, Colorado.  We let our imagination run wild with their new offering, Eye of Ra!  Psycho Penguin Vanilla Porter is a big star at the Beerwerks and we loved creating our take on their signature porter.  Oh Snap is Odyssey’s winter ale and is scented with winter spices.



Sanitas Brewing of Boulder, Colorado also joined with us to create something exciting for the Bacon and Beer Classic.  The trusted us with their Saison and the mysterious Black IPA.  We try very hard to capture the essence of the brew and the thoughts of the brew master as each brew is created.



Fate Brewery of Boulder, Colorado has joined FSW to create three soaps from their favorite Brews, Uror Gose, Apollo Tsai and Coffee IPA.



Zephyr Brewing has joined our collaborative venture with their delicious and divine smelling Peanut Butter Porter

Some of our favorite brews come from very small companies who produce their brew with passion.  Mama Bear of Boulder is one of those breweries.  The combination of sweet tea and pale wheat ale is to die for!

One of our favorite collaborations was with Strange Craft Beer Company of Denver, Colorado.  They shared their Breakfast Grapefruit IPA.  Our customers love this fresh grapefruit scented soap!



Industrial Revolution Brewery of Erie, Colorado furnished us with their new and wildly popular Blonde Stout to create a soap that represents their awesome product.

Upslope Brewing Company of Boulder, Colorado furnished FSW with its Premiere pour, Citra Pale Ale



Ska Brewing of Durango, Colorado has a fabulous pour, Autumnal Molé Stout, spiced with south of the border peppers.



Nothing is better than a coffee stout and Horse and Dragon Brewery of Ft. Collins, Colorado produces one of the best – Sad Panda Coffee Stout.  We all love how the soap turned out with its cute little coffee bean topper!

Something Brewery of Brighton, Colorado has imaginative brews and even more imaginative brew names!  We especially love the Plum Walker with the Zombie on the label and we made a fun Zombie looking soap!

Another tons of fun brewery is Big Choice Brewing of Brighton, Colorado.  The soap we made for the is one of our favorites (we love the name),  Tarts and Crafts!  Lime ale with a cherry on top!



For those who have gluten issues, we have not forgotten you!  We have a Hard Cider soap from Wild Cider  of Firestone, Colorado.  The scent is heavenly and it looks good too!

Denver Beer Company of Denver, Colorado is working with FSW on a trial basis.  This is our version of their awe-inspiring Pretzel Assassin.

4 Noses Brewing Company of Broomfield, Colorado was reluctant to share their Logo for our soaps but they have been very supportive and have allowed us to name their brewery and beer name, El Jefe and Bareback Blonde in the description on our label.  We love these soaps!


Fun soaps and mysterious brewers.  There are a few breweries who chose not to collaborate with any soap maker for their own mysterious reasons and we respect that but we did have such great fun making the soap!

We are preparing for this event every day.  We have the best beer soaps and we are ready to travel!
