I’ve used WLP570. However, it’s not just the yeast that will get you there. Ingredients, mash temp, fermentation temp and how you condition the beer has great effect. It’s very easy to end up with something more like a full-bodied Tripel than a Golden Strong.
You can’t go wrong with WY1388 or WLP570 (also Duvel). A recent golden strong my brother made turned out quite well with 570, it had a nice fruitiness it that definitely is reminiscent of Duvel. I bottled a golden strong last Tuesday that I fermented with WLP545, which is reportedly from Huyghe (Delirium Tremens, etc.). I haven’t tried the final bottled conditioned product, and there seems to be a lot fruit in the aroma (bananas maybe) and some spiciness, which is the yeast character was I shooting for. As for a favorite? I think may stick with WLP545 because I like the ester profile and it seems to ferment well. After two and a half weeks my beer went from 1.085 to 1.008 and finished with (a very smooth) 10.3% ABV.
I was looking at the yeast strain guide on Mr Malty ( Mrmalty.com ) and didn’t see WLP545 so I sent an email to Kristen England asking, and the reponse I got was Huyghe. I checked the map and I see what you mean, I’m not sure what to think now.
I really like the 1388, works really well for me. But I just brewed a 1 bbl batch using 3522 Ardennes yeast, which I believe is A’chouffe yeast. Curious to see how this one works.
Yeah, I don’t know… White Labs already has strains sourced from most of the breweries in that region. Could be Caracole… BLAM says they have two different house strains, and given the White Labs description, the stronger one used for Nostradamus is a possibility.
I start mine at 68, let it set for 2-3 days, then raise up 1* a day until it hits 75, and let it ferment out, usually 10-14 days. Once done, I’ll chill 10* a day until it hits 34, and let it stay there for a week or so, whenever I feel like bottling.
I forgot to mention earlier that the Huyghe identification came with a disclaimer, which was basically that is was more of a best/educated guess rather than a positive ID. I opened a bottle of my beer last night and there is a promininent banana-like fruitiness to the aroma. It’s been a while since I’ve had a bottle of Delirium, or Caracole, so I can’t quite recall their yeast characters very well.
That does sound really good.
As for temp, I started around 68*, though the first night it crept up to 73* while I slept before I got the temp down again the next morning. After that it was a fairly constant 68*.
I checked the Duvel conditioning schedule two Januaries ago for a failed gluten-free golden strong ale (it turns out lagering in my garage was a bad idea), and I was surprised to see the low temps.
Cold conditioning can be beneficial for all beer once fermentation is done, not just lagers. Be careful, though, about the aggressive schedules you read about from commercial breweries. You want the beer to be done fermenting, and I’ve found that you’re unlikely to get that to happen as fast as they can on the commercial scale.
