Brewing a 2nd brew on the left overs of the first

[BrotherMalice]

I am going to be doing a 2nd brew on the day that I bottle my 1st brew and have heard/read that people leave the gunk (trub?) in the bottom of the FV and add their next brew directly onto it, is this a good idea? - not sure of the reason people do it but like the idea as it wil make the 2nd brew day a bit quicker :)

Very good idea but I would tip it into a clean sterilized container first and clean and sanitize the fV first before putting the yeast and wort back in. I should go like a rocket watch out for overflowing FV :thumb:

Cheers for the advice, was hoping to avoid cleaning the FV (lazy) will have to empty it into somewhere sterile while I clean the FV as I am hoping to get another ribena wine on again sometime this week so wont have a spare FV (FV2 now has holes in it...)

Its going to be the same beer so quite looking forward to seeing the results of the 2nd batch :)

As has been mentioned above, it's ok to do this but MUCH better if you harvest the yeast from the FV and use a clean/new fermenter. I do this all the time for numerous reasons. Here's some pics to help :

looks interesting (only scanned through as I am in work) would you still use the yeast that comes with the kit as well as this?

Nope, The trub from the previous brew will be rammer jammer with live yeast. You can save the new packet of yeast for a rainy day.

Right, I am now an FV down due to making it into a boiler

Which only leaves me with 2 options:

1/ remove the trub to a sterile pan or similar clean/sterilise the FV & but the trub back in FV1 & put the new brew in and off it go's

or

2/ leave it all in the FV1 and just put the new brew in as is

just a bit worried about contamination with all the changing around....

Number 1 assuming you're confident with your cleanliness. However, if you're not confident with your cleanliness, you should try another hobby!

For the future, get some conical flasks of eBay. Easy to sterilise and use and makes this job a lot easier.

Put it in any clean sterile container and cover it over with tin foil, clean out your fv put the yeast back in and drop your new beer on top. That is what I do. :thumb: :thumb:

If you put a new brew straight in you will have a few weeks worth of dried crud on the edges which have been exposed to the air waiting to fall into your nice new brew, also that crud will attract the peskie little fruit flies which are beginning to appear. Not worth the risk for five minutes of cleaning especially if you have slaved over the beer for hours.

One quick query I have regarding this...

Say I was to use the trub from one in another brew... How would I go about transferring it? If I were to transfer straight to new FV, would it be best to mix up new brew first, then pour it in to it straight from old FV, or best to scoop it out, so that it doesn't touch the mess on FV from sides?!

Might give this a go with my next brew, using the yeast from the wherry...
