Located in Washington DC at the new development: The Wharf, Potomac Distilling Company is currently producing four different types of rums. (White, Spiced, Green Spiced, and Coconut)
The process for making all of our rums starts with a 200 gallon blend of equal parts: black strap molasses and raw turbinado sugar.
We then add yeast, vitamins, and nutrients to the fermenter when the temperature gets to about 90 degrees and let it ferment for 5 days at minimum.
When fermentation starts, the sugar is around 18 brix and 0 percent alcohol. After 5 days of fermentation, at 6 brix of sugar and 8 percent alcohol, we are ready to distill. (We have 5 fermenters working at all times).
The distilling process begins with a stripping run exclusively in our pot still, yielding about 40 gallons of rum at 35 percent ABV (alcohol by volume).
We then collect all of the stripping runs and put them back into the still, at which point we decide which type of rum to make.
If we are making White, Gold or Spiced Rum we will incorporate the column still where we engage all 4 bubble plates. This will produce around 75 gallons of rum at 155 proof. The finished rum is placed into a holding tank to rest for 5 days, allowing some of the volatile fumes to work their way out.
For our Green Spiced or Coconut Rum, we will engage the botanical basket and either stuff it with spices for Green Rum or toasted coconut for Coconut Rum. This produces the same yield but the Rums are now much more aromatic, as all the flavors have infused together.
These rums will also rest for 5 days, after which we begin the process of proofing down from 155 to 80 proof (40% ABV). The proofing process takes an additional 3 days using a very slow, steady drip from our water filtration system. Once this is completed, we start bottling; 6 bottles at a time, and then hand label and hand wax.
Thrasher’s White Rum
80 Proof – Light citrus zest with vanilla backbone. After a bit of time in the glass, funk and smoke linger. The rum has a soft, subtle heat with coating mouth feel, finishing round and soft. Notes of butterscotch and orange peel are present at the end. This is the perfect rum for a traditional Daiquiri.
Thrasher’s Green Spiced Rum
80 Proof– Our flagship and the first of its kind – It is a botanical-based blend made to impart flavors reminiscent of English gin. We developed the recipe through experimentation, using herbs grown in our own rooftop garden. They include: Lemon Verbena, Lemongrass, Lemon Balm, Mint, Green Cardamom, and Lime Peels. This light, distinctive spirit is herbaceous, floral, and vibrant with hints of green citrus. It’s a mixing spirit; intended to enhance cocktails like Thrasher’s signature Rum & Tonic. It also works perfectly for a Mojito or Jungle Bird.
Thrasher’s Spiced Rum
80 Proof– Spiced rum doesn’t have to be sweet and sugary. Our version is a dry spice-forward spirit that imparts flavors of fall and winter. Featuring an aromatic mixture of Star Anise, Clove, Allspice, Cinnamon, Vanilla, and Orange Peels. This flavorful spice blend is further steeped for 4 days with our signature White Rum for added depth. The result is a bold and zesty rum that can be either sipped or mixed. No sugar is added at the end of distillation.
Thrasher’s Coconut Rum
80 Proof– Most Coconut rums do not come at 80 proof! We wanted to make a Coconut Rum that was more savory than Sweet. It begins with 60 pounds of raw coconut, steeping overnight in the still. We then load the botanical basket with 5 pounds of toasted coconut to impart a ‘nutty’ aroma. Following the run, we add 5 more pounds of dehydrated coconut and let it steep in the rum for 4 days. There are 3 different expressions of coconut in our rum, resulting in natural flavors and a delicate, smooth mouthfeel. No sugar is added at the end of distillation.
Thrasher’s Gold Rum
80 Proof– Thrasher’s Gold Rum has a medium golden hue. It is soft, mellow and round, with subtle hints of smoke and oak. Smooth and Soft on the palate, It has been Aged for 4 months in medium char, medium toasted New American Oak barrels.
