About this calculator
Estimate how many glasses you'll get from a wine bottle based on pour size and spillage/waste allowance, and calculate revenue and profit per bottle sold by the glass.
Frequently Asked Questions
How many glasses are in a standard 750ml bottle?
With a 150ml pour and no waste, a 750ml bottle yields exactly 5 glasses, but most operators use a waste allowance which brings it down slightly.
What is a good pour cost percentage for wine by the glass?
Most restaurants target a pour cost of 20-30% of the glass price, meaning a 70-80% gross margin on wine by the glass.
Why include a waste allowance?
Spillage, over-pouring, corked bottles, and sampling for guests all reduce usable volume, so building in a 3-7% waste buffer gives more accurate profit projections.
