A recent post discussed the strength of various joints in a cabinet. Biscuits were much maligned there. So I dug out the magazine Wood November 2008 where extensive tests were made on various joint methods. True, Mortise and Tenon joints are still king, but biscuits weren't to shabby either. A red oak butt joint made with biscuits had a pull apart strength of 1000 pounds and a shear strength of 250 pounds. So how many bottles do you want to put into your cabinet? Plus the ease of using biscuits, give those critters a break.
