If you are selling rectified spirits to bars, you may lose out on this business. However, if you are selling directly to consumers, which is a much bigger market, this will likely help your product.
If a consumer really liked a rectified spirit, that individual would rather go to Costco or Safeway to buy a bottle of it rather than go to the bar and pay 10x the price for one drink. This could also open the markets to new tastes by exposing consumers to the rectified beverages...in fact, this may be a boon because the bar has done free marketing and some trial sales already for you.
