So you are aware, that master list of bottle weights was created by Dave (our founder) over the years from all the inventories he’s counted and all the bottles he has weighed. The Master Product Database has over 27,000 products for you to add, but not all of the liquors will have bottle weights. Unfortunately, there is no tare weight list online anywhere or any liquor company offering bottle weights. Because of that, we have the most popular brands and their weights, but it is possible for the list to get outdated, and in addition manufacturers often change the bottle shape or amount of glass they use. Because of this, you should definitely trust your own scale to correct any major discrepancies.  

In addition, most people don’t know that two unopened bottles of the exact same brand can weigh an ounce or two different (thus the 1 – 2% margin of error), so if the weight is off an ounce or two, it’s not a big deal at all, but if it’s more than that, we suggest correcting it by weighing with your own scale and following the formula below.
