Raspberry peanut butter mead, this happened after racking into tertiary. Primary and secondary had raspberries freefloating in the container, so it miiiight just be floating bits of raspberry. When I shake it up, they briefly sink and float back up.
I’ve done both but I keep coming back to distilling for this very reason. The hardest bit can be drinking it though. For a sugar wash you’re looking at like £6 per batch and you end up with around eight bottles of 40%. I don’t want to tell too many people what I do and even those that know often don’t want to drink it because they think they’ll go blind (which we know is obviously false).
