For the past 6 months, I added just BrewTan-B to my recipes (both BIAB & DME); I'm definitely seeing clearer beer, and perhaps some flavor improvements (I have not done side-by-side comparisons). I brew small (2.5 gal or less) batches, so I bottle condition with fresh yeast (currently CBC-1) and ascorbic acid - and bottles are held around 75F for the first week.
For a "new years day" BIAB brown ale, I used OxBlox in place of BrewTan-B. I also added ...
1) YOS (2 g yeast/sugar per gal at 90F for 30 min),
2) mash capping,
3) and no sparge.
With all the changes, I feel that I got a better beer.
I have another BIAB brown ale (different recipe) in the pipeline with OxBlox, YOS, mash capping, but a dunk sparge with boiled water. Hydrometer samples suggest this this beer will be similar to the "no sparge" beer.
As noted earlier, I have a DME recipe early in the pipeline where I included YOS, mash capping, and a "low stir" approach for adding the DME. If it turns out well, I may post a full recipe & process steps here.
My guess is that I'll end up with the following changes to my brew day
1) YOS
1) OxBlox for BAIB (or BrewTan-B for DME)
3) "mash" capping
4) BIAB: dunk sparge with boiled water (I have a tea kettle that heats quickly)
eta: while my approach to YOS extends the brew day about 30 minutes, it's also 30 minutes for casually milling grains, measuring hops and minerals, etc.
