Hey guys,
I'm brand-new to sour brewing. I'm trying to do a Berliner Weisse, and opted for a split primary. I bled off 1/3 of the wort to do a Kolsch fermentation and the other 2/3 to Wyeast 5335 lactobacillus. My intention was to combine them for secondary. After 5 days, the Kolsch is just about done, but when I check the lacto batch... nothing. Nada. I haven't taken an official pH read, but it just tastes like plain old wort, no tartness at all.

Now the confessions to the things I've done wrong:
1. I didn't run a starter. I did direct pitch, as instructed on the package.
2. I thought I'd be able to hold the wort at around 70 degrees, but we've had a bit of a cold snap, and it's running closer to like 64. The package says it should produce anywhere above 60, but 64... probably not optimal.

So here are my options:
1. Stay the course. Maybe the cold temps and no starter, it's just taking its time getting going. RAHAHB.
2. Go ahead and combine the two batches, and assume I'll just have a bland hefe.
3. Try to kickstart the lacto by putting the whole fermenter in a warm bath and bringing it slowly up to 90 degrees.
4. Dump it. I can't think of why I'd do this, since bad beer is better than no beer.

Any words of wisdom?

lacto isnt capable of fermenting beer on its own. It can only attenuate it a bit. Y are going to need to blend them and let the kolsch yeast work

Wait, so it won't produce lactic acid unless yeast fermentation is active at the same time?
 
Every sour I've made is a blend (which I'd definitely recommend over a single bacteria strain for insurance and comolexitity) but it should still be souring it slowly. Thins is, it takes a while unless you do like a sour worting at 115 or so. At room temps lacto is much slower. It still won't really properly ferment the beer though
 
That's fine. I'd always been planning to blend for secondary. I just wanted to let the lacto have its way with the wort before I introduce the yeast. I was worried the yeast would overpower the lacto if I pitched combined from the start.
 
Warm the lacto to 90-100F to get it sour then combine. If you cant heat it then blend together to let the yeast ferment it then wait 3 months. It might get sour.
