I was wondering if anyone knew how small micro breweries ascertain the correct fills in their bottles? do they use calibrated glassware to measure to get it spot on?

also do they weigh the finished product?

cheers
 
I thought most use lazer beams to check the fill levels, but happy to be informed otherwise.

No, I dont know any brewery anywhere that actually weighs filled bottles. Glass manufacturers calibrate their bottles at the design and manufacturing stage and mould in a fill level in mm. You can usually find this number around the bottom periphery of the bottle - something like the "52" on the Coopers bottle I am currently drinking. That number is the correct fill level in mm from the top of the bottle - in this case 52mm from the top.

thats what my mate says but i thought the guys did it by also measuring with calibrated jugs and glass wear?

im drinking a hoegaarden cru atm and your right wes it does say imprinted on the glass at the bottom 0,33l 45mm. So if the really small micro breweries dont have the wizz bang bottling equipment how do they get it spot on? by eye?

Not quite, most bottle fillers use a dip tube of some sort. The dip tube will determine the fill level cutting off the flow to the bottle when the dip tube, which provides air/gas relief is covered. It is up to the brewery to calibrate when this occurs and whether the fill level is correct. If all this sound a bit sus, then pay a visit to a full scale bottling line and see how many underfills get rejected. How else do you think the brewers get their take home beer?

there is also a ultrasonic sensor that can detect that the bottle has a cap and is also the correct fill level with in the tolerance.
 
ultrasonics, lasers, gamma rays to look through cans, cameras and computers.... all get used on "big" brewery bottling lines. but most micros would probably be making do with eyeballs. Fill with a diptube to get it right, eyeballs to make sure the filler got it right.
 
Sensors in form of "Lazer Beams" on the line out of the filler. When QC runs are done, they weigh a tare bottle then about 6 bottles to find the average.
 
One of these....

LAZER - Always been a pet hate, ranks up there with expresso.
From Light Amplification by Stimulated Emission of Radiation = LAZER. Give me an S

Be right back... just need to run down to the atm machine...

I recall being told that it really should be referred to as Light Oscillation by Stimulated Emission of Radiation, but the military refused to fund LOSER guns so it got a name change.

I know at least a couple that do.

Take an empty bottle with a crown as your tare, take the weight of a full bottle as the net, use the specific gravity of the beer to convert the weight to volume.

Fast, easy and non-destructive.
