Clean glasses?

TerrieBootson

My da, big Guinness drinker, wouldn't drink in a pub where the Guinness didn't stick to the glass - the glass was clean when emptied. He said if the glass was clean there was still detergent stuck to it and the beer tasted off. Is there anything to this? I wouldn't be a beer drinker myself

Don't think it makes a big difference to taste in an artificial beer like Guinness but it could make a massive difference to the way it pours and the head.

If there is any form of crap on the glass the CO2 in real beer nucleates on it and goes back into a gas making it difficult to pour.

Think its the same with nitrogen. Guinness is all about the texture of the beer created by using nitrogen instead of CO2 because nitrogen has much smaller bubbles.

I think you're overcomplicating the issue. If the beer tasted off he should hand it back. Any sensible pub would replace it without issue. Finishing a pint and then looking at the empty glass is not a logical way to determine whether the beer you just drank was good or not.

I'd much rather someone brought a pint back and say it's off. It gives me a chance to actually fix the problem.

Tgeres a load of bollix surrounding Guinness from the two stage pour to the direct tge head and how it reacts with the glass. I remember seeing something about “lacing”, how the head clings to the glass after you’ve drank done, or finished your pint. IMHO if it tastes off, give it back and complain but otherwise enjoy your pint.

Your father was probably right, if there's too much detergent in the glass washer, none of the drink will stick to the glass and it can taste off too. You will notice it more with newer glasses as there's less imperfections/scratches on the inside.

The rings you see left on the glass when you slug a pint comes from imperfections in the glass, whether it be from tiny scratches from years of use or even a bit of a dirt, this causes a) the beer to foam/release more gas b) the liquid to stick to it.

So this would affect a pint of Coor's Light exactly the same way as a pint of Guinness?

Well no, one is carbonated and one is nitrogenated, so not exactly the same, it's more obvious with the creamier head you get from nitrogen.

However, you would see a lot more "fizz" on a older, more scratched glass, versus a pint that looks more "dead" if too much detergent is used, obviously different lagers have different amounts of foam but you would have noticeable rings from a pint of Coors in a "dirtier" glass.

It's essentially the same reason why most companies will have nucleation on their glasses, normally via etching at the bottom.

But any off taste would be in the lager, just as much as in the stout?

Surely more noticeable in a lager?

artanevilla

Yes.

But you never get the same level of widespread scientific guff about 'good' and 'bad' pints of lager, funnily enough.

Or any other beer.

I've had plenty of "bad" pints of lager handed back to me.

In my experience, lagers are probably the most likely to taste absolutely rank, and in 99% of cases it'll be an exceptionally slow moving line.

Any suggestions for cleaning glasses at home? Been using baking soda as a cleaner under hot water with OK results.

Macy0161

I don't know how I ended up using them, but denture tablets are what I use at home, and then a hot water rinse and air dry. Gives the father in law the necessary schtick on his nitrosurge diageo anyway 😶

the beer revolu

Hot water and washing up liquid and a scrub has always worked fine for me as long as you rinse well.

The Continental Op

These eraser type sponges work really well

thats just an example. Clean as normal and wipe the inside around while the glass is still damp with one of those.
