Both the Opshaug Pale and Bure Gold that I’m brewing with my resident Opshaug Kveik are still fermenting when they should have finished out a couple of days ago, though to be fair the trend graphs provided by Tilt Pro are now beginning to flatten out a little so I’m looking forward to getting both of these put away in the coming week.
I don’t pay attention to the absolute values reported by Tilt, but I think it’s safe to say that both of these brews are going to be way stronger than they’re supposed to be; Bure Gold should be around 4.3% (previous efforts were 4.3 and 4.2%) and Tilt thinks we’re nearer 4.6% right now, Opshaug Pale was aiming for 5.3% in the recipe (5.9% adjusted for actuals) and I’m presently in the neighbourhood of 6.7%.
The only negative aspect of this continued fermentation is that my finishing hops will have had their contribution diminished a little due to the production and venting of CO2, but there’s nothing I can do about that now other than record what’s happened and adjust subsequent brews using this yeast accordingly.
#wisdom: I’m not sure if it’s a trait of WLP518 or the way I’ve harvested / re-used it, but my Opshaug Kveik has not started as furiously as expected, and taken much longer to ferment. If the Opshaug Pale turns out well then let’s repeat it, but dry-hop much later.
