Default Filtering post boil?

Hi All,

I have recently started to use the BIAB method for all grain brewing.

This weekend I made a 5 gallon batch of doppelbock.

It is extremely cloudy.

I used 1 tablet of whirlflock with about 4 minutes left in the boil. I used a hop bag.

Chilled from boiling to ~80* in less than 10 minutes.

I whirl-pooled the chilled wort with my mash paddle/spoon and let stand for 20 minutes.

The cloudy wort only settled a couple of inches.

I dumped everything into the fermenter and brought it down to 40*.

Now there is 4-5 inches of cloudy material on the bottom of the fermenter.

I'm not sure if it will adversely affect the beer or not.


Can I filter the wort on the way out of the boil kettle and into the fermenter?

Will this cause any issues? Not recommended for any reason?

I was planning on purchasing a filter to filter after fermentation and on the way into the keg.

Chris

I filtered my last batch going from the BK to a carboy. I originally purchased a funnel with a screen but the mesh in the funnel was so fine it was constantly clogged so I purchased a stainless steel strainer with a handle from my LHBS. That worked really well. I still kept the screen in the funnel since the mesh is smaller than the strainer but it did not clog nearly as bad after adding the strainer. Just remember to keep a bucket of clean water and a bucket of sanitizer easily accessible to rise and re-sterilize to clear a clog.

When using a strainer, my wife usually holds the strainer (sanitized) and uses a sanitized kitchen spoon to scrape the hops/trub around and let the liquid pass through. When the strainer is full, she scrapes all the solids into a bowl. That works fairly well, but a lot of fine sediment still passes through.

The last batch I used a siphon to move the wort from the boil kettle to the fermenter and it worked really well.

Filtering out trub is very difficult. A hop back does a good job.

Your probably better off letting it all settle out and then racking it to another fermeneter.

OR

just leave it in there and RDWHAHB. I don't think it makes a huge difference in the finished beer.

I pour my cooled wort into my bottling bucket that is lined with a 5 gal paint strainer bag. Open the spigot to drain into the carboy, remove the bag. Easy.

I use a hop back loaded with rice hulls. Keeps anything but clear wort from reaching my plate chiller which empties directly into the fermenter.

That's a cool idea. How do you santize the rice hulls? Do you boil them first or just recirculate some of the boiling wort thru the hop back?

I recirculate until I see the batch temp dropping down near the 140*F mark then I shoot straight through.
