PG40 GlasswasherI work in,  what can be a very busy pub/accommodation/ restraint. I work behind the bar and I have been told to put glasses (hot) straight from the dishwasher into the fridge.

 

Is this right, because it’s making the beer flat. And it’s embarrassing for me. None wants to buy a flat pint, without taking it back. You wouldn’t go to a supermarket and buy a mouldy loaf of bread without taking it back would you?

Thankyou

  1. I’ve never done it but wouldnt putting glasses into the fridge be a good thing, there is nothing worse than using warm glasses to serve a pint. I wouldn’t say that it’s making the beer flat, because its so cold its giving the appearance of being flat. We can alway let it drop into the glass a bit to give it an adjustment when needed. In Australia they even put glasses in the freezer, thats why they have peeling lips, they say its the sun but we know different. ha! ha!

  2. Hello Michelle, glasses should be allowed to air dry and cool to room temperature after being removed from the glasswasher unless you have something like the Air Rack from Clenaware which passes room temperature air around the glasses to speed up drying.

    By putting hot glasses in the fridge you are causing condensation to form, this will make the fridge more prone to bacteria growth as it is not at the proper temperature, cause issues with any items you have in the fridge, increase the electricty needed to run the fridge as the chiller will be working hard to cool down the sudden increase that adding items at 55-65 degrees C can cause.  Condensation will also form on the inside of the glass, this is what is making your beer go flat.

    Beer should only ever be served in a fully dry room temperature glass to give the best dispense, even if the beer is chilled prior to pour.

     

    If you would like some literature and information guides on proper glass care drop me an email on direct@proton-group.co.uk and I will forward it onto you.

    • i just read the above and agree but as a technician I currently install heineken ice all glasses are in a glass freezer and the pint has perfect head retention I just think a lot of the time the glasses are poorly washed and as u say not left to dry natural before entering the glass fridge or freezer would u also not recommend further renovation and checking date on pint glasses

  3. Hello Craig

    I would only recommend extra Renovation if the water break test has been performed and the glasses have failed it.  If the glasses are air dry and put in an air cooled fridge the problem of condensation will be reduced to a point where it wont be noticeable or cause issues (If the glasses is “Beer Clean”.  The problem occurs with wet glasses in a standard fridge where you will get condensation and ice crystals forming inside the glass.

     

    The thing to remember is there is no actual magic bullet but several factors that have to be checked one after the other, so you might want to consider checking the following things.

    1. Try allowing a few glasses to air dry then put it in the fridge, then see if these give you the same head loss problem.

    2. Do a water break test on a glass if it fails then you need to Renovate, if it passes the test do not Renovate as over Renovating can damage glassware.

    3. If you have Renovated the glasses recently and it fails the water break test next time the glasswasher engineer is on site have them check the dosing levels of the detergent and rinse aid, over or underdosing can cause issues.  Also have the temperatures of the wash and rinse tank checked.  Glasses should only be washed in water that is 55 degrees centigrade and the rinse/drying temp should be no more than 65 degrees centigrade, this ensures that there is no scouring during the wash cycle, that the rinse aid has time to work rather than being baked onto the glass and that there is no thermal shock on the glasses that can cause them to explode when the door is open.

    4. Give the machine a full clean out.

    5. Are you in a hard water area and if so do you have a water softener?  If you do then check that the softener is working and has it been regenerated.

    6. If you are not using a Clenaware machine that uses fresh water every wash then how often is the wash tank on the machine emptied per serving period?  Remember that if the wash tank is not emptied after every 3-4 washing cycles then by the end of the serving period you will be washing glasses in dirty water.
