Review: Proof Traditional Old Fashioned Cocktail Syrup

Review: Proof Traditional Old Fashioned Cocktail Syrup

Proof is a new brand of cocktail syrups, ranging from steadfast (Traditional) to oddball (Maple Bacon), made by a bartender-led crew based in Decatur, Georgia. The collection is designed to go beyond mere sugar and water, and have bitters already in the mix. Per the company:

These high quality cocktail syrups are an “everything but the bourbon” approach to craft cocktails and feature our oleo-saccharum made the traditional way from organic cane sugar, with our added bitters. Simply mix .5 oz of any PROOF Syrup with 2 oz of your favorite bourbon or rye whiskey, to easily create the perfect textbook old fashioned.

We checked out Proof’s “Traditional” expression, both on its own and when mixed as directed.

With its reddish hue, this is clearly something beyond a “traditional” syrup — it’s the color of watered-down Peychaud’s Bitters, indicating from the start a bit about how it’s been doctored. The nose of the plain bitters is spicy, with cinnamon and nutmeg distinctly heavy, and the palate is quite sweet with brown sugar and a bit of a honey character. Cardamom notes become evident as the finish emerges.

With whiskey (I used Jim Beam Distiller’s Cut in a 4:1 ratio as directed), the combo was a hit. Very spicy — there’s clearly plenty of bitters added to the mix here — it follows through on the promise that it makes two-ingredient cocktails completely possible. The whiskey shines, the bitters shine, showcasing a clear clove element. Perhaps the sugar quotient could be elevated a tad, but that’s perhaps splitting hairs.

I’m not sure I need maple bacon syrup but, what the hell, given the strengths of the “Traditional” version, I’m willing to try.

    Proof Syrup seems to be a fraud. Made order on 12/8, paid through Amazon. Proof Syrup has yet to reply to status of order, after 6 email attempts to their contact site.
    I won’t recommend Proof Syrup to anyone.

      My order worked fine.

    Same here. Ordered on 12-3. Have not received delivery. No return on my emails. Phone number that shows on credit card is bogus.

    Uh oh. My order, charged 10Dec, hasn’t arrived or shipped either. They may be overwhelmed…I’ll give them a couple days to respond to my e-mail, then do a charge-back.

    Have faith. Mine was ordered in early December and arrived on Jan 3rd. Likely a postal delay. Not a fraud.

    I ordered mine in November through the website. Took a bit maybe, but came through as ordered. Very happy with the product.

    DO NOT BUY!!

    I ordered three of these prior to Christmas, after getting an email saying my order would be delayed due to demand. I got my delivery with only one of the three bottle I ordered. the packaging was much less than I expected. The bottle I received was wrapped in 50gal trash bag with zip tie around it. The bottle itself was extremely sticky, I had to cut the bag off of the bottle. I recommend the syrup by woodford reserve. Spend your money with a company that knows how to deliver.

    Not a fraud at all…ordered the Traditional version on January 23 and received on January 28. Product came in an appropriately sized package and wrapped in a unique flexible cardboard cushion surrounded by more stuffing to keep it safe and secure.

    Tried my first Old Fashioned today with 0.5 oz syrup and 1.5 oz. HW Rendezvous Rye. Very good for the first attempt…will experiment with different ratios but the flavor is spot on.

    Rob – Order arrive on-time. I need to experiment with the ratios because it seemed a little sweat to me.

    Ordered yesterday afternoon or tried to, the address for the order kept reverting to an old address. Thankfully I noticed the shipping address had reverted on the website because I did not receive an email confirmation of my order. Order was not listed under my email account on their website. When I contacted customer service to try and get the shipping address updated, I told them if the address could not be updated to please cancel the order. This was so I could try and place the order with the correct address a second time. I was told by the rep to “Get a drink of water and take several long breaths”. NOT APPROPRIATE. Horrible Customer Service. Promptly asked for an immediate cancellation. Still no reply from their customer service despite it says within 24 hours and that 24 hour mark is in 2 hours. Unfortunate as I tried this product at a friend’s house and it was delicious but the horrible customer service and patronizing manner of the rep is not worth it.

    I had zero issues with Proof syrup when it comes to shipping, what I did have issues with was when I asked if I could swap the pecan syrup out in the big pack due to an allergy to pecans the person was incredibly rude and lost my business.

    Did you know that Proof has an “F” rating with the Better Business Bureau?

    I want you to know that no matter how much you spend with them, they don’t care about you or want to make it right.

    I have spent $582.64 on proof syrups for old-fashioned and margaritas. So a good customer. I then signed up for a subscription because they were offering a free whiskey sour to do that. Subscription came and no free bottle of whiskey sour.

    I thought I would try cosmo and tasted like chemicals and medicine and looks like milk. So as a long-time customer who has spent almost $600 with them I told them that I wanted a refund or replacement and even offered to mail back the bottle.
