Most Frequently Asked Questions

What is the highest grade of glass (or Flint)?
“Super Flint” is the highest grade of all glass, it has various names like “Crystal Flint” but what sets this glass apart from all other glass is its clarity and brightness. Nearly all high end Brandies, Cognacs, Gins, and even Vodkas will use this type of glass. This is a grade of glass we are very familiar with, because customers want this type of glass for their bottles.


What Is The Minimum Order I Need To Place?
Basically most manufacturer will want you to order at least one 40’ Container of glass which equates to 22,000 to 25,000 of a 750ml bottle. Obviously a smaller bottle would be a bigger quantity (375ml = 40,000) and a larger bottle like a 1.75L bottle might be only 11,000 pieces in a 40’ container.


Should I do my Decoration/Labeling in China?
Each bottle decoration/ label is unique, and for the best answer to this question we would always recommend to simply give us a call so we can advise you of the most cost effective way for you.
For Example: If you are doing a paper or plastic label, then I would say no as the pricing in the USA, and China are very similar. However if you want to do a silkscreened or baked on logo then China is definitely the way to go saving as much as 40-60% having this done in China.

Do They Use Lead in The Bottles Or Decoration?
This is probably the most common question we get as a result of a big problem years ago with a toy manufacturer who had lead in their paint. Ever since this incident the Chinese government has come down hard on any company using lead. Some glass bottle companies will tell you lead is no big deal especially if it is on the outside of the bottle, but it is a big deal so you need to make sure you know who you are dealing with. Here is an article that discusses it
I can assure you that all of our glass and decoration meets all USA guidelines, and we even take it one step further by providing a “Health Certificates” and or a “FDA Certificates” from an independent lab with each shipment.


Do I Need To Wash The Bottles Prior To Filling?
The pat answer would be Yes, but we know for a fact that over 50% of distilleries to not wash bottles at all, and the most common way they clean them for dust is to blow air into them, and use a vacuum system to suck out any particulates. This is why we pack the way we do and use shrink warp since we know washing is not as common as we would like.

Do You make Closures?
Yes we do a variety of both custom and standard closures from screw top to cork tops. We will be happy to help you design your very own custom top for your custom bottle.
