White Labs Kölsch yeast

I've had this yeast in the fridge since November and it went out of date in May. Thought I'd brew up a starter to see if it was still ok.

Only had enough for a 2.5L starter. Didn't do anything for 48 hours, but once it kicked in its went great guns. Fun to watch it working away on the bottom of the demijohn.

I pitched it into yesterday's pale ale brew and this morning it's gurgling away like crazy. I was fearing the worst with the BBD on the yeast, but it's absolutely fine. It's the first White Labs yeast I've tried and I'm impressed.

Hi,

Is it smelly farty yet? It can be a proper sulphur bomb whilst fermenting, great yeast though;)

It doesn't smell farty as far as I can smell - I've got a blow-off pipe into some starsan and it smells like Witbier

I've just used this for the first time in a blonde ale and fermented it cool at 16 degrees.

It's difficult to describe the flavour but I really like it and it works well in a blonde ale with low IBU's. Malty but clean and refreshing.

I'm fermenting mine at room temp (20-22C), so it's gonna be fruitier. The only alternative is putting it in my cellar which is sitting around 14-15C this time of year. However, that may be too cold for the yeast.

Despite what the packet says you can ferment at this temperature, it fermented clean like a lager yeast, see the Brulosophy website for details. Maybe they put the range higher to ensure you get that Kolsch yeast taste.

In that case, I might pop it in the cellar since I only pitched the yeast last night, so it's got less than 12 hours fermenting (I'd guess).

I've regularly fermented this at 14. Very clean.

I've put it in the cellar now - we're sitting at 15C down there today, so it should be fine.

I've checked on it today and it's still fermenting fine at 15C. Quite looking forward to this as every other beer I've made has fermented in the kitchen at 20-22C.

I used this yeast last year it turned out very clean, lets the maltiness shine through and dropped absolutely crystal clear.
Seem to remember i fermented at 15c and it was pretty sulphury. :hat:

I find it hard to describe the taste. I would say a hint of banana but very very subtle.

If the starter is anything to go by, fermenting at higher temperatures gives off lots of fruity esters - it was actually very drinkable even without being hopped.

Mind you, I'm expecting far less esters fermenting at 15C. I've heard about this bring a sulphur beast, but that it ages out ok. I'll just leave this in bottles for s couple of months before trying it.

Don't bottle until any sulphur smell has passed...apparently! (I've never used a smelly yeast so it's just what I've heard!)

Cheers Rolfster. I'll keep that in mind. My standard practice is 14 days primary, then rack to secondary for 7-14 days. I'm hoping that any sulphur smell should have gone by that time.

I've went a bit mad on brewing in the past couple of weeks - two brews and plans for another next week. I reckon a brown ale is on the cards.

I dropped mine into a secondary and took it down to 3c for 2 weeks, after that the sulphur odour had dissipated. My kolsch became really good after about 2 months in the bottle.

That sounds similar to my experience with the Wyeast Kölsch equivalent - that took more like 3-4 months to come into its own. Just had the last few bottles this weekend.

Damn, mines never going to last that long. It's already had a caning and it only went into the cornie 8 days ago.

Well hopefully you saved some for a rebrew?
