Finer Crush For Biab

[jayse]

I don't think this thread is any longer a retail thread so maybe move it to all grain yeah? No objections?
It won't be filtered through paper or anything just shifted :lol:

I would've thought measuring the gravity to check efficiency would be done before adding any additional fermentables?

Good point, I'll take a sample before the sugaz. I normally only measure the OG as a guide to how many brain cells I am likely to lose and also to see if I am within guidelines if I am trying to copy a commercial style.
However for the current exercise I take your point.

Edit: yes move it, the 'commercial' aspect was fulfilled when Ross et al sent me the fine crush

Over simplified: if you have a testing tube full of trub/cold break and drop the hydrometer into that vessel will your hyro sit on the trub? I think so.Therefore a false reading.

Fair enough I suppose. Not quite needing a filter paper to get an accurate reading, but I see the logic in recommending that samples be filtered in the ASBC guidelines. Takes the whole issue completely out of the equation.

The last sample I took to measure SG was taken after dumping cube contents into the fermenter just before pitching yeast. At first there was a decent amount of debris seemingly suspended in the wort, but I left it on the bench for 10 minutes then returned, and the bulk of it had settled out to the bottom of the tube, and my hydrometer sat above it happily without disturbing it, so I am happy with the results of the reading in that aspect.

However, I tested my hydrometer in demineralised water and found it was floating at 0.096 instead of 1.000 at 20 degrees. To test the accuracy of my hydrometer, I thought of using a sugar solution at 20 degrees to test at typical Starting and finishing gravities.

Beersmith tells me that 1 litre of water at 20 degrees with 130 grams of dissolved white table sugar should give a reading of 1.050, while 1 litre of water with 30 grams of sugar should give a reading of 1.015. Anyone think that these figures are wrong on their calculations?
