Should I dump a batch with rubber smell?

I have in bottles a batch smelling like chemicals or rubber. I'm thinking keep it a while, and check if the smell fade out. Is this possible? Or I'm just wasting my time with this batch? As side note, this batch is, from a parti-gyle, a second run. The first run, a porter, is OK.

Splitting Batches / Dilution

My current setup is an 8-gallon aluminum kettle with a weldless valve and Blichmann Brewmometer (which, even when 'shielded' from flame, does not work, not happy with that investment). This serves as MLT and brew kettle. I live in a tiny rowhouse with no yard so I brew in my kitchen, but have a decent range and can get a 6.5 gallon volume up to boil in about 20-30 minutes with 3 burners going. What I have been enjoying quite …

How do I calculate mash efficiency with BeerSmith2 when doing a partigyle?

I designed a barleywine in BeerSmith2, made it, plus I made another beer afterwords from the same grain. My mash efficiency on the first runnings turned out to be 75% (I put the grain bill and pre-boil 1.092 and 5.85 gallons into BeerSmith2 for that). I purposefully didn't mash-out so I could do the partigyle. I got 3.6 gallons of 1.034 wort out of the mash tun on the second runnings. What I wanted to do was make a new …

Will Adding an Active Mash to a Non-Active Mash Get Enzyme Activity Started Again?

Background: A friend of mine does ten gallon batches of big beers, so has a lot of grain. After mashing, his technique is to fly sparge with 170 degree water. I understand this shuts-down enzymatic conversion. He'll run out of sparge water, drain maybe 2/3 of the liquid from mash tun, and then lets me do whatever I want with the mash tun in order to make a second-run (partigyle) beer. What I do during his sparging is to create …

When adding grain to mash tun for second runnings, how long should I let the new grain mash?

This probably illustrates my lack of knowledge about mashing in general, but I'm going to brew a barleywine with first runnings, and a stout with the second runnings. I'm going to be adding 1 pound each of Crystal, black, and chocolate malts, and possibly a couple pounds of wheat malt after I have drawn off the wort for the barleywine. I'm planning on adding the additional water, add the grain, stir, but then I'm lost. On Denny's page describing batch …
