@Miraculix Sorry, forgot to take up your yeast recommendation. I like Pub Ale a lot and it is a favourite among homebrewers for good reason, but since I do not have a dedicated fridge for fermentation and Pub is the British strain most sensitive to temperature overshoots, I dare not use it. The German judges are really good at detecting fusels. I will see how WLP007 works, which is basically a Nottingham with more character. My current alternative would be WY1469 which also flocculates well and is my favourite flavour-wise. I just don't have it at hand atm.
I'm very open to dry-hopping my beer. There are a number of hops that work well when added together with the yeast, like Golding, Target and also my home-grown Tango. I think any mild hop would be fine, British or German. I'll probably test a few. It also makes sense to hop the beer a bit more than would be conventional, because even the Munich Helles that win competitions nowadays are hopped more heavily than would be according to style.
But I wanted to ask, can you give me any definitive examples of dry-hopped Best Bitters? As I said I only know of the one.
