In a medium saucepan over low heat, melt the butter and whisk in the flour. Cook, whisking constantly for 2 to 3 minutes, being careful not to brown the flour. Whisk in mustard, Worcestershire sauce, salt, and pepper until smooth. Add beer and whisk to combine. Pour in cream and cheese, whisk until well combined and smooth; this will take 4 to 5 minutes. Add hot sauce.
