Someone was looking for a table of potential starting gravities for fruits for me and it occurred to me that some of you may have something like this. I would appreciate if any of you could point me in the direction of a table that has this info. Thanks,  |

This is awesome. I just want something I can guesstimate with. So how do I convert this info to specific gravity? |

http://en.wikipedia.org/wiki/Original_Gravity#Original_Gravity_.28OG.29.3B_Original_Extract_.28OE.29The OG is the specific gravity measured before the commencement of fermentation. From it the analyst can compute the OE which is the number of grams of sugar in 100 grams of wort (°P) by use of the formulas or table discussed in the Plato article. The symbol p will denote OE in the formulas which follow.

My brain just isn't wrapping around this. Also, I want to know what the specific gravity of, say a pound, of strawberries will be. It won't be an extract or juice. I will be adding it to my must. |

OK, I will have to figure this math equation out for you. Give me a couple days and I will try and post something with PPG (points per pound per gallon) or specific gravity per pound. Should be pretty simple, but give me some time. Remind me if I forget to post after about 2-3 days.

OK, found a few minutes of free time and came up with this. Hope it attaches.

Maybe I'll find some time to experiment and see if these actually come out close. Only need one or tow apples.

This just gives me a starting point. I am sure one batch of fruit to another batch of the same fruit will give me different yields. I am happy that I have an idea of what I am messing with. |

commercial juices are cool for calculating.
the labels list grams of sugar per serving of a certain ml. For instance, I am fermenting some cranberry juice that is 36g sugar per 240ml serving. 36 divided by 240=.15 That means 15 brix or approx. 1.060.

Good to know. I am making some fruit meads though and don't plan to use juices. This is useful for my multi-flavored ciders, though! |
