First Biab seemed to go too well!

Post #1 made 12 years ago

Did my first Biab yesterday a simple draught Bass recipe. It seemed to go really well I had no problems, unlike the cricket, so I am assuming that the finished beer is going to taste crap to punish me :nup:

Used the BIABacus and it was really helpful and pretty accurate I was aiming for 23L and OG of 1.044 and got 1.042 and 25L so I can live with that. And the inaccuracies their are just as likely that a put more water in than I thought than any other reason.

I took one extra measurement according to uncalibrated bathroom scales I used 1.1kg of propane for the day heating the water from an initial 8C

Also I used a no chill cube should any adjustment be made in terms of hop additions or finnings to take into account the slower cooling rate?

Congratulations boff on your first BIAB which I noticed you did without asking for any help ;).

I see you also worked out how to use the BIABacus for yourself and that all went smoothly. Nice work :salute:. And there is no need to fear that this beer will turn to crap. Why should it? Your next one might though, read this post :lol:

Here's a quick check on your numbers (although we can't really learn much from one brew)...

Estimated 'Metric Sugar Points': 23.0 (volume units*) x 44 (gravity points) = 1012 'Metric Sugar Points'
Actual 'Metric Sugar Points': 25.0 x 42 = 1050

[Other measurement system users can just use their own volume units for this quick 'sugar point' check. Gravity points are the specific gravity without the 1.0 bit. In other words, a hydrometer reading of 1.042 means 42 gravity points.]

So, you were a little more efficient than the BIABacus predicted which is where we would like you to be, on average. (Individual brews and base grains can vary wildly as can your measurement sample and instruments so never be surprised on a brew to see your numbers being out. If an inconsistency repeats itself regularly, then worry.)

As for your no-chill hop question, this post here and subsequent posts will lead you to some answers.

Good on you :thumbs:,

Congrats boff, I've been doing BiaB for 2 years and almost never hit the exact numbers. But, I think I have only had 2 bad brews out of 48 . Relax and enjoy the ride , this could actually be your best beer !!

TBH I was amazed how close I got to the numbers. I knew it was a first try and I my aims were limited to making sure that the system worked and I get a drinkable beer.

I will fine tune as I go along but as far as I am concerned life's too short to aim for accuracy to the nth decimal point. As far as am concerned close enough is good enough. But Biabacus seems a great tool both to give a starting point and in future to improve consistency.

The Beer itself is fermenting well I couldn't resist a crafty sip after 48hrs and it tastes promising no hint of infection, it looks a bit light in colour but if that turns out to be the biggest criticism of the beer I will be happy. It suprised me that after only 48hrs @ 20C it tasted like most of the sugar had been munched by the yeast. I will leave it in peace and start taking hydrometer readings in a couple of days.
