I brewed a beer with Wyeast 1318 (LAIII) over the weekend, and ran out of time to make a starter and save yeast from that like I had planned. I dry hopped today with 3 oz of hops. I've never tried washing or reusing yeast in any way before - am I able to save anything from this batch to use again, or should I just buy another pack next time I brew and make time for a starter?
