Has anyone out there used any hop extracts recently. I bought an ounce from the hbrew store in town for 20$!!! The guy in there didn't know what strain they were or the alpha acid but you can taste two drops in a pint of bmc type beers. How should i calculate using them instead of just spiking yellow fizzy bmc beers?

I don't know much about hop extract other than the rumors/truths that the biggies use it even though they deny it. I do wonder if you get hop extract twang from it though like you do with malt extract.

er...it's kinda important to know the stats on the extract to calc the dosage.

If you have no way of finding out, I would do a small test batch with the extract as the only addition (and @ 60m) and eval the results against a known recipe to get a round about guage of what kinda IBUs you threw in. Adjust accordingly then scale to your full size batch.

Is this an aroma oil or a bittering extract? Bittering extracts should have some indication of the concentration, aroma oils won't.

It sounds like you have the hop oil not the extract. It's very hard for homebrewers to get the extract. The oil is nice for adding hop flavor and aroma to beers but does not add bitterness. Try using a few drops at bottling and go from there. If you keg you could just pop the top and add more if needed.

The hop oil is usually a mix of flavor and aroma hops. Freshops.com has an oil and it tells which hops are used.

If you do have the extract tell me where to get some. The extract should have the AA% on the bottle.

Hoptech has alpha-acid extract, but does not report the AA% on the bottle.

You would think it would come with directions for use.

The directions say 1/8 tsp per 5 gal is 1 IBU. The 2 oz bottle will add 16 IBU to 30 gallons.

Extracts don't contain alpha acids, they contain iso-alpha acids (or maybe tetra-). Which is to say they are pre-converted, dissolved & ready to add. The whole AA%/utilization concept does not apply.
