I've done brewery tours in the US, Ireland, and England and the Fullers tour is really good. The guide we had (Lisa) was knowledgeable, had been with the company a long time, and had a great personality for the tour. She was alternately friendly, funny, and informative.
The tour was organised around the four main ingredients of beer (barley, water, hops, and yeast) and it showed the old way and new way of brewing at each stage. Often you see an old copper and brick version and then you see the new, computerised and stainless steel version.
Lots of the photo opportunities are in pretty poor light. If you bring a camera, be sure to be ready for dim indoor lighting.
On the up side, you see a real working brewery doing its thing. You really do sometimes step out of the way so someone can walk by and keep doing his job. On the down side, this means they generally only do tours during business hours. Skive off work one afternoon, though. It's worth it.
Parking near the brewery is limited, so be sure to allow yourself some time to find a spot. There's ample pay-and-display parking, but it's a lot of twisty turny streets in there. I'm not sure how easy it is to get to this on public transport. We drove. That's a shame, because somebody's not getting the full experience. The tastings at the end were generous and we got to sample lots of different beers. I had only really had the London Pride and Honeydew before the tour. I'll be watching for the Jack Frost Christmas ale and Chiswick Ale now. read more
