Hi title says it all.

 

I have cleaned the brewing vessels, thoroughly rinsed, StarSan and another rinse.

 

Brew 1 is Lion Ale, #2 is Coopers Lager.

 

Lager is showing a surface activity a slight foam, but Ale is not showing the usual foam that I would expect, I threw some more yeast in ale last night, but still today it looks very sluggish.

 

I'd thought the night temperatures could have slowed it down, but I took temps of liquids today and sitting happy 21C.

 

Are some brews like this as my Coopers Stout almost jumped out of the BV with a big foaming head?

 

Thanks, Al.

From memory, lagers are supposed to ferment at a lower temperature than ales and take longer.

 

15 Deg pops into my head and my lager brews took 2 to 3 weeks at this temperature before bottling.

Thanks but this is Coopers Lager which is apparently, just a lighter ale. Anyway, thats the one thats showing activity.

 

Im just surprised that the Lion Ale is not showing surface bubbling activity; its probably working OK but Im not used to that.

 

Al.

If you aren't already, you could try hydrating the yeast in a clean glass of tepid water with a pinch of sugar or similar - if it isn't looking a bit frothy after 15 minutes, then it could be off.

 

Some brews just take a few days to get bubbling properly, so I wouldn't stress too much quite yet.

Hi matey.

 

I always prestart the yeast that way if thats what you mean.

 

For example the first thing I do is mix water and sugar and then add yeast. Then after the BV is filled with goodies, add the fermenting yeast solution.

 

Cheers, Al.

What yeast are you using?

 

The kit yeast that you get with the Coopers Lager is not a real Lager yeast and will ferment OK at 21 but will generate ethyl acetate if fermented at 24C or more.

Im using the yeast that came with the kits eg Lion and Coopers. Except on the 2nd day of no visible activity I added another yeast to the Lion Dark Ale, which has made no change.

 

Day 3 still at 21C, activity on Coopers Lager, slight activity Lion Dark Ale

Is the specific gravity changing in beer - will show if it is just fermenting slowly.

Larger is bottom fermenting so might not show much foam. Check the gravity as if it was quite warm then could be finished. Did you give it a good stir at the beginning (once all ingredients / yeast added)? As might have not got enough oxygen to build up a healthy yeast cell start.

 

I've not brewed for a good 8 years. Was a all grain brewer. Seeing these posts has got me wanting to brew again!
