Can I save a low OG brew?

[Justinian]

Recently I tried my first all-grain brew with the BIAB technique. My efficiency was not good though (I think my bag was too small) and I ended up with an OG of 1.030. I went ahead and dumped in the yeast anyway.

Obviously I'm going to end up with a pretty watery brew, but I'm really invested in it because I used homegrown hops for the first time. I had the idea to make a second, strong batch, pitching yeast from the first batch, and mixing the two batches before bottling.

My question is: does a low OG affect the viability of the yeast? Will I have a healthy trub at the bottom of the first batch from which to harvest?

Your thoughts are much appreciated!

The yeast will be ready to go so re pitch and brew the bigger OG beer.

Your yeast will be good. Your idea of mixing the beers is a good idea. Having said that, the first batch may be good on its own. Sometimes it's good to have a lower abv beer. It may be out of balance though. Taste it and see what it lacks, and then you'll have more of a direction for your next beer if you decide to mix them.

Thanks for the responses guys!

I didn't think to taste the first batch - I just assumed it was kind of a dud.
