spirit measuring equipment
I just broke my favorite liquid measuring tool for the bar. HUGE DRAT.
It was ~5 ounce borosilicate (lab) glass graduated cylinder. It had a pour spout and--the most critical feature--was marked in OUNCES and milliliters.
I got it at IKEA at least ten years ago.
So far I can't find anything else that has the same features--Pour spout, ounce markings, easy to read, glass.
And this might do in a pinch, but the markings are molded in which makes it much harder to read. OTOH, they won't wear off which afflicts all/most of the newer pyrex measuring stuff.
If you know of a supplier of lab glass anything that comes marked in ounces, or if you have any suggestions for a great bar liquid measuring vessel, I'd love to hear it.
The OXO measuring cups are great. The 1/4 cup (2 oz/60 mL) is probably too small for your needs (perfect for many cocktail uses though), but they do sell a 1 cup (8 oz/240 mL) size as well as bigger. Pours great.
If you're math savvy, converting mL to oz isn't too bad when you realize that it's 30 mL to 1 oz. Also tsp and Tbsp are 5 and 15 mL or 1/6 and 1/2 oz, respectively. Once you train yourself to do it, it becomes quick and can flip flop easily.
The other option is to have two - one in oz and one in mL.
I do like the OXO cups. Too bad they don't come in glass.
I am a hopeless addict when it comes to lab glass so I have basically arrived at the same conclusion about just converting to ml on the fly, even if it means making myself a little cheat sheet. You'd think as a sciences major I wouldn't need one, but after a Manhattan, all bets are off.
After some heavy google whispering I did discover something called an apothecary beaker that looks like a perfect solution-- glass with oz. and ml. Vintage via ebay, etsy or similar, or new (with better markings) by the case from lab supply place.
I'm pretty sure Pyrex has a 1cup version (and those all have both ounces and ml). Not as cute as those apothecary beakers, but pour just fine.
Edit: never mind, that one doesn't have each of the ounces marked clearly, at least that I can tell from the picture.
I have a 1 cup Pyrex and it has the even oz numbered and the odd oz hashed, but the markings start at 2 oz.
I like the Anchor one splatgirl linked in her first post, it is marked in 1/2 oz and tsp. Though it doesn't have a spout, I don't see why that would be a problem unless you are pouring into a test tube. I have never had a problem with cocktail shakers or glasses. It is around $1.50 at Walmart.
