It’s really hard to do math when you’ve had a few drinks so the ABV Glass does all the work for you (thank you ABV Glass!) It’s a pint glass with lines and printed measurements for beer, wine, or spirits, showing you the alcohol level in each drink. Now you can know exactly how much alcohol you’re drinking. Great for mixing drinks in too. While that’s cool and all, I really wish this glass could do a little more- like clean up the kitchen or fill in for me at work on Fridays.
