Are there any methods that don't require a lab setup?

Hello everyone We're having slight problems over here with a new project.... How the hell do you figure out the proof of naturally infused spirits? The pineapples have a ton of sugar and water in them, the sugar making the liquid denser therefore the hydrometer is completely inaccurate. Our antonpaar is also out of the question because of the damage the sugar would do to the equipment. We're at a loss over here and can't find anyone who has seemed to have similar problems. Please help, thank you!!! -SC
