Please help me settle an argument Polish beer Zywiec

Hello,
I hope the Polish members here can help me settle an argument I have with my father. I regularly buy a Polish beer Zywiec from a Polish shop in my town in Gloucestershire and then have bought the same bottle from my local Tesco and the taste is totally different. Zywiec has a slightly tangy taste and when I bought the bottle from my local Polish shop the taste was different from the Tesco version. Please anyone who drinks this excellent Polish beer can they tell me if it is possible the tesco version is different to the Polish supplier I am convinced the taste is different. I have read on the back of the bottle and both seem to have the same information on them yet the Zywiec I buy from my Polish friend is much better and Tesco's is not very good
Thanks Richard

Sorry man , by law and regulations the beers shoud both taste the same ....Unless something is fishy hehehee

The taste of beer can be affected by light, length of storage, heat.

away guy I thought this also about the regulations maybe it is me and my taste buds, the way I solve this is I will buy it from my Polish friend's shop and forget Tesco
Thanks

Yes like i say "fishy" maybe tesco batch of beers were exported under some influence of unatural circumstances ?

Yes I agree with you what I need is some other members here to do the taste test this would really help as I am sure they would notice a difference

It's possible that in Tesco they simply kept It in ****** conditions - too warm and so on.

It is a fact that in some value supermarkets like the Winn Dixie the same brand products, like coffee, beverage...

are much different quality, i mean much lower...

Tesco isnt a pov market ! and Tyskie isnt a pov brand!

Yup. It sounds like it was chilled, warmed then chilled again. This really screws with beer.

sup Shell?

Zywiec will knock you on your *ss not matter what it tastes like. Good stuff maynard!

Yeah its good so is Okocim

The answer is easy- Tesco charge disgusting amounts for favorite tipple, once you have parted with half your days wage for one bottle it tends to taste like ****.
