Clearing Agents
Welcome back to Danger's Lab! I'm your host, DangerDave---
My next project is going to be a side-by-side comparison of the use(s) of bentonite and sparkolloid. I have used sparkolloid exclusively for my signiture wine---Dragon Blood. The lees left by this additive are very light and fluffy, even on the second or third racking. I have to be very, very careful when racking to make sure I do not pick up any of this white fuzzy-looking stuff with my pump. I usually do well, but occasionally, I'll bump my racking cane or something, and have to let the carboy sit and settle out for a few more day (or weeks).
I once heard someone say here that they used bentonite in the primary and treated later with something else (it may have been sparkolloid). So, I currently have a batch of Dragon Blood in the primary, almost dry, wherein I added bentonite per the package directions. After it's dry and degassed, I will add sparkolloid and see if the bentonite helps to "capture" the fluffy sparolloid and create a more solid layer of lees during clearing. I will provide pictures here as it clears, so we can compare to the use of sparkolloid alone.
As soon as this batch hits the carboy, I will begin two more batches of Dragon Blood, and use the sparkolloid alone (or in just one of them).
We will see who clears the quickest, and examine the resulting lees. Stay tuned!
