Harvesting from Duvel

[Riot]

I think you missed a line reading Brew Like a Monk. It says that Duvel Moortgat uses a single strain for every beer, but the circumstances for the strain are different when used for bottle conditioning. Not sure exactly what that means, other than it is the primary yeast used in bottles.

Edit: This thread got me thinking about doing a Duvel clone, so I bought some of the Tripel Hop on my way home from work. So far I've given 100 ml of ≈1.03 wort and shaken the crap out of it. Will feed it more in the coming days and we'll see brew day and fermentation go in the next week.

Right, read to fast.... so it's definitely the same yeast in the bottle then. That is pretty weird about the "different circumstances".

Please post recipe and how it works out for your clone.

Recipe will be 5.3kg pilsner malt, 750g dextrose. 1 oz saaz FWH, 1 oz styrian goldings at 90, 1 oz saaz at 5. Shooting for 21 litres to the carboy.

Just finished brewing that and figured I would post an update. I hit my numbers pretty much dead on with the recipe above. 30 litres preboil, 23.5 postboil, 21 to the carboy. OG is 1.068 and I just pitched an estimated 250 cells. I have high hopes for this, the ramped mash took me two full hours

Figured I would throw up another update having just racked the batch to secondary. This was the slowest ferment start and progression I have ever seen. Took almost 4 days to get a krausen and I'm still not sure its totally done. Gravity is 1.003, I was hoping for 1.005. That being said, it tastes pretty damn good so far, not hot at all. Definitely has that characteristic Duvel tartness going on. I'm gonna give it a couple more weeks before I cold crash and bottle.
