Yeast coming out of my airlock - spoiled brew?

[jpoc]

I started a brew a few weeks ago. I used a commercial extract in a tin (Coopers Aussie Lager) and a #62 Czech Pilsner enhancer and some 1118 yeast and low carb enzyme.

I have made this recipe many many times with no problems. This time, when the fermentation started, the brew foamed up and gobs of yeast were forced up into the airlock. I cleaned and replaced the airlock many times over until things quietened down. This was with a 23 litre brew and a 30 litre plastic barrel.

I did not do anything different from normal. My usual practice is to start two barrels off at the same time with the same recipe and the twin batch is normal.

Today came time to think about bottling this brew so I opened the barrel to measure the SG (OK fully fermented) and noted that there were lots of clumps of dried yeast on the walls of the barrel and the smell was not nice.

OK, it could be that dried out yeast smells bad and the beer should be OK but perhaps the batch is ruined.

Any opinions?

Thanks.

If you can, I am not familiar with those barrels, start EVERY fermentation with a blow off tube set up. The yeast will do what the yeast will do. Sometimes there is a lot of krausen and sometimes not much, even with the same recipe.

As to the smell, some yeast smells awful to me, others I don't really notice at all.

Everything sounds alright as long as the beer tastes good.

The barrel only has a facility for a single airlock. I have been using four of these for two years now, pretty well all busy all the time and this is the first time that I have had this problem.

I bottled the beer today and the beer itself looked OK, I will know more in a few weeks.
