Wyeast 1335 British Ale II

The first 2 packs didn't expand, they were delivered to our door a small box with a small icepack that was melted when we got home ( i had a mishap that took us to the emergency room) we ordered 2 more that my wife picked up Friday morning. She smacked them on the counter before laving to come (home in Verona). They were stored properly (I've been brewing for almost 40 years). They puffed up about half way. we pitched them anyway. the result was it got us about a half of full attenuation. After dealing with this I ordered a smack pack of Wyeast 1056 and that brought me to the attenuation I was looking for.
