The idea to start their own brewery first came two years earlier, when they realised that there was only one other brewery operating in London.
Wanting to "bring brewing back to the heart of the capital", they enthusiastically set out on their mission to do just that.
During 2007, the lads' idea developed. They were joined by an experienced Hampshire brewer by the name of David Welsh, and before long they found themselves happily sipping their very first beer, Wandle Ale (3.8% alc.).
Since then, Junction Ale (4.5% alc. ), described as having "a deep amber colour and spicy hop character", has been added to their list of offerings.
Junction Ale has even picked up a few awards, including the 'Beer of the Festival' at the 2010 Battersea Beer Festival.
There's also their Powerhouse Porter, packing a potent punch at 4.9%. This one has "a rich, dark chocolate flavour and an aroma of toasted malt and winter fruits". Sounds pretty good to me.
Now, what better way to support your local brewery (if you're living inside the M25, it's local) than by paying the brewery a visit, meeting the brewers, watching how it's all done, and trying the beers for yourself.
Sambrook's Brewery offers tours, to groups of ten or more, six days a week (£10 Mon-Fri; £12 Sat).
If you can't get a group together, they also run an open evening on the third Wednesday of every month.
For more information on the tours and open evenings, call 0207 228 0598.
A tour of the brewery takes about 90 minutes and includes tastings.
You'll be delighted to know they don't scrimp on these samples. You'll be treated to a whopping two pints of their beer during your look around the brewery, so maybe line your stomach with a sandwich before you embark on the tour or you might be seeing two breweries and twice as many in your tour group by the end of it.
Should you enjoy the fruits of their labour (you most probably will), there's an on-site shop where you can purchase bottles, kegs, gift packs and more.
