Hat would be solution for replacing perle battering hops for a Ed worts kolsch receipe? I have plenty to get tetttanger, cascade, hallertau and Saaz. Reciepe calls for perle as bittering. In order to match ibus, for the reciepe I would have to use about 3 times as much ttteanger for the bittering. However on all the hop substitute charts none of my other hops are equivalent to perle. I would like to brew today and this is my only hold back. Thanks for any help.
