Title: Canned blackberries / gravity?
Post by: liquidbrewing on August 07, 2012, 07:00:39 PM
I just brewed a wheat that I want to add some Oregon blackberries to.  How do I find out the specific gravity of the 15 oz can I'm going to add?

On their website, it's listed as 12 brix.  I assume that's per can.

Can you provide me the link?  I scoured their site (evidently not) and couldn't find any info.   Also 12 brix, how much will that increase my OG?

not much. (15 * 12 + ((128 * 5) * x) / (15 + (128 * 5)

where x is the og of the batch. This assumes a 5 gallon starting volume.

That's for the aseptic purees.  I just bought the whole blackberries from the grocery store and blended them up myself.

you should be able to calculate sugar content from the nutrition info on the label as well. are they packed in water or syrup?

**EDIT**

Looks like about 90 grams of sugar per 15 oz of blackberries in heavy syrup. so less than that for light syrup.

Beersmith lists blackberries as contributing 1.005 per lb, so that would add just 1 point in 5 gallons.  You can safely ignore it at that level, or add it in if you like.

Ooops!  Sorry.
