We like to add a certain amount of highly aromatic dessert pears to our otherwise tannic perry, and to pear based distilled spirits. Potomac is a good one because it is highly fireblight resistant. A droup pear with lovely, delicate aroma when fully ripe.
Brandy (precocious bittersweet pear)
The earliest to come into bearing of our English Perry pear trials. Smaller, manageable tree. High gravity tannic fruit. Fireblight susceptible.
