I would cut the pears up, then put them in 1-gallon ziplocks and freeze them. After they're frozen thoroughly, I would take them out, and let them thaw in the primary fermenter with some k-meta. As they thaw, they'll turn into the pear equivalent of apple sauce.
12 hours after K-meta, add a pectinase.
12 hours after that, check the acidity & sugar levels; adjust. Get your yeast starter going; pitch it. Pitch yeast nutrient after the lag phase, when fermentation is rolling.
I haven't had the pleasure of aging a pear wine made this way, myself - I started to once, but then combined it with an apple wine.. And the 2nd time I had pears, I combined it with apple from the beginning... But the time I started it, I had the pears frozen, wine fermented and degassed it with my vacuum pump post-fermentation - it cleared in 2 days. Aroma, color, clarity, it was gorgeous.
