Oh, score!
You're in for a real treat here, I think.
I didn't weigh the bananas that went into the 1-gallon,
It was just roughly half of the 40lbs I had sitting out.
No biggie, probably closer to your 10 than I originally assumed.
I don't know that it'll be 'dry'.. That's kind of what caught me off guard about it.
The residual sweetness from the bananas soaked in the brandy, seems to have been enough to balance it right out.
But, thats gonna be a little batch-dependent (fruit quality dependent)
Mine was a 3 gallon batch as well though, and the 1/2 gallon of brandy was a perfect ratio
My grandmother, I showed her just the Banana Brandy..
She locked her lips on that bottle and started cuddling it..
It went down "too smooth" she says, just how it was..
She wants more, just bananas and brandy.
Had a 375ml bottle 'extra', on top of the 1/2-gallon for the batch.
Everyone did double takes, that tried it.
So...
Fair warning
