Add the pineapple wedges and lime wedges to a bowl and cover with tequila. Try and make sure the wedges are mostly submerged. I found using a shallow 8x8 inch baking dish worked best. Soak the pineapple for 1 hour or overnight. You can then use the pineapple to mix with the drink (remove the rind before blending) or to serve on the side of the drink. I used mine only on the side of my drinks and sprinkled them with a little salt + chili powder.

Add the cubed pineapple and limeade to a blender and blend until smooth. Pour over a glass of crushed ice. Add the beer and tequila (if using) and stir to combine. Garnish with a slice of pineapple and mint leaf if desired.
